In one month, Jason earns $32.50 less than twice the amount Kevin earns. Jason earns $212.50. Write and solve an algebraic equation to show how to find the amount that Kevin earns.
Answer:
Step-by-step explanation:
2K - 32.50 = 212.50
2K = 245
Therefore, Kevin earns 245/2 = $122.50
We can double check this by reversing the solution:
122.50 x 2 = 245
245 - 32.50 = 212.50
Therefore, we can be certain that our answer is correct!
What is the sum of all the integers between √18 and √75?
answer 2639
Step-by-step explanation:
We are asked to find the sum of all the integers between 19 and 77.
We will use sum of arithmetic sequence formula to solve our given problem.
, where,
= Sum of n terms,
n = Number of terms in the sequence,
a = 1st term,
d = Common difference.
Since we are asked to take the sum of all the integers between 19 and 77, so common difference is 1.
Therefore, the sum of all integers between 19 and 77 is 2639.

Given that 1+5b+9c=1 , 4a+2b+3c=2, 7a+8b+6c=9
what is 741a + 825b + 639c?
Answer:
741a + 825b + 639c = 1375/9.
Step-by-step explanation:
To solve this problem, we need to first find the values of a, b, and c that satisfy the given system of equations. We can use any method of solving systems of linear equations, such as substitution or elimination. Here, we will use the elimination method:
Multiplying the first equation by -4 and adding it to the second equation, we get:
-20b - 36c = -2
Multiplying the first equation by -7 and adding it to the third equation, we get:
29b + 45c = 8
Multiplying the second equation by -29/20 and adding it to the third equation, we get:
-21b - 39c = 67/10
Now we have three equations in two variables. We can solve for b and c using any method, such as elimination or substitution. Here, we will use substitution:
From the second equation, we can solve for a in terms of b and c:
a = (2 - 2b - 3c)/4
Substituting this expression for a into the third equation, we get:
741/4 - 825/2 b + 639/6 c = 9
Simplifying and solving for b, we get:
b = (3/5) - (3/5) c
If this helps, please mark my answer as brainliest
Substituting this expression for b into the second equation, we get:
(27/5) c = (2/5)
Solving for c, we get:
c = -(2/27)
Substituting this value of c into the expression for b, we get:
b = (3/5) - (3/5) (-2/27) = (11/27)
Substituting the values of a, b, and c into the expression 741a + 825b + 639c, we get:
741a + 825b + 639c = 741[(2 - 2b - 3c)/4] + 825b + 639c
= 741[(2 - 2(11/27) - 3(-2/27))/4] + 825(11/27) + 639(-2/27)
= 741(5/27) + 275/3 - 426/9
= 1375/9
Therefore, 741a + 825b + 639c = 1375/9.

Answer:
Step-by-step explanation:
The angles GCJ and ACB are congruent.
So GCJ=ACB=63°.
And in Triangle ABC the sum of all angles is 180°.
Such an angle of BAC is calculated by:
The sum of all angles = ABC + BCA + CAB
180 = 90 + 63 + CAB
CAB = 27°
Then again angle KAI and CAB are congruent then
KAI = 27°

Answer:
The solution is ([4], [19]).
Step-by-step explanation:
To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:
y = 4x + 3 (Equation 1)
y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:
y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:
4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)
4x - 3x = 7 - 3
x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:
y = 4(4) + 3 (Substituting x = 4)
y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).
Solve for x

Owen has 50% more cash than Sandra, and Sandra has 20% more cash than Amada. How much more cash than Amada does Owen have, if Amada has $4.35?
Answer: $3.48
Step-by-step explanation:
Amada has $4.35. Since Sandra has 20% more cash than her, Sandra has $5.22. Owen has 50% more cash than Sandra, so he has $7.83. The difference between $7.83 and $4.35 is $3.48.

Answer:
w≥77
Step-by-step explanation:
Multiply 11 by 7.
Answer:
[tex]w\geq 77[/tex]
Step-by-step explanation:
How would you get w by itself so that it makes it simplify?
Either you Multiply/Divide and Subtract/Add.
In your case you have [tex]\frac{w}{7} \geq 11[/tex]
To get w by itself you multiply 7 to both side leaving w.
[tex]7*\frac{w}{7}\geq 11*7[/tex]
Seven cancel out on the left side leaving w.
11 * 7 = 77.
[tex]w\geq 77[/tex]

A fence post that is 5 feet tall casts a 2-foot shadow at the same time that a tree that is 27 feet tall casts a shadow in the same direction. Determine the length of the tree's shadow.
8.5 feet
10.8 feet
12 feet
21.4 feet
Answer:
Let s be the height of the tree's shadow.
We set up and solve this proportion:
5/2 = 27/s
5s = 54
s = 10.8 feet
The length of the tree's shadow is 10.8 feet.
Which of the following combinations of side lengths will form a triangle with vertices X, Y, and Z?
(A.) XY = 18 mm , YZ = 20 mm , XZ = 39 mm
(B. ) XY = 17 mm , YZ = 20 mm , XZ = 36 mm
(C.) XY = 16 mm , YZ = 20 mm , XZ = 37 mm
(D.) XY = 17 mm , YZ = 19 mm , XZ = 37 mm
Answer:
(A.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 18 mm, YZ = 20 mm, and XZ = 39 mm. This is because the sum of the lengths of any two sides of a triangle must be greater than the length of the third side according to the triangle inequality theorem. In this case, XY + YZ = 18 mm + 20 mm = 38 mm, which is greater than XZ = 39 mm, satisfying the triangle inequality theorem.
(B.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 20 mm, and XZ = 36 mm. This is because XY + YZ = 17 mm + 20 mm = 37 mm, which is greater than XZ = 36 mm, satisfying the triangle inequality theorem.
(C.) A triangle will not be formed with vertices X, Y, and Z with side lengths XY = 16 mm, YZ = 20 mm, and XZ = 37 mm. This is because XY + YZ = 16 mm + 20 mm = 36 mm, which is not greater than XZ = 37 mm, violating the triangle inequality theorem.
(D.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 19 mm, and XZ = 37 mm. This is because XY + YZ = 17 mm + 19 mm = 36 mm, which is greater than XZ = 37 mm, satisfying the triangle inequality theorem.

Which equation is true when n = 4?
Answer:
The answer is D
Step-by-step explanation:
2(n+6)=20
2 times n equals 2n
2 times 6 equals 12
so, 12 plus 2n equals 20
make 2n the subject of formula so, 2n= 20-12 (the sign will change when coming past the (=) sign
2n= 8
n=2/8
n=4

Convert to military time:
9:15 A.M.
Answer:
To convert 9:15 A.M. to military time, we can follow these steps:
1. Determine if the given time is in the morning or afternoon. In this case, "A.M." indicates that it is in the morning.
2. Identify if the given hour is between 1 and 11. In this case, the hour is 9, which falls within this range.
3. For morning hours, we keep the hour as it is. So, the hour remains 9.
4. Write the minutes as they are. In this case, the minutes are 15.
Putting it all together, 9:15 A.M. in military time is simply 0915 hours.

The tires on Jasmine's bicycle have a circumference of about 70.4 inches. Find the approximate diameter of each tire. Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
The approximate diameter of each tire on Jasmine's bicycle can be calculated by dividing the circumference by π (pi). Using the given circumference of 70.4 inches and rounding π to 3.14, the calculation would be as follows:Diameter = Circumference / π
Diameter = 70.4 / 3.14
Diameter ≈ 22.45 inches (rounded to the nearest hundredth)So, the approximate diameter of each tire on Jasmine's bicycle is 22.45 inches.
The approximate diameter of each tire is 22.42 inches.
What is the diameter of the tires on Jasmine's bicycle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle is expressed mathematically as;
C = 2πr
or
C = πd
Where r is radius, d is diameter, and π is constant pi ( π = 3.14 )
Rearrange this formula to solve for the diameter:
C = πd
d = C/π
Substituting the given value of the circumference, we have:
d = 70.4/3.14
d = 22.42 in
Therefore, the diameter is 22.42 in.
