Answer:
a= c+16
a-c= 16
Step-by-step explanation:
a = b + 12
b = c + 4
adding both eq.s, we get:
a+b = b+c+12+4
a+b = b+c+16
a = c+16
a-c = 16

Answer:the answer is 9998.
Step-by-step explanation:
The largest 4 digit number divisible by 2 . The number should be divisible by 2 or multiple of it. So the largest 4 digit number is 9999 it is not divisible by 2 so the earlier number 9998 can be considered so as it is divisible by 2. It is the answer is 9998.

Answers
Answer:
19.334
Step-by-step explanation:
First I multiplied.
15.24 x 1.64 = 24.9936
Then I convert my answer to British pounds.
24.9936 = 19.334 British Pound Sterling
Answer:
1.36
Step-by-step explanation:
15.24 = 8.44 + 5x
subtract 8.44 from both sides
6.80 = 5x
divide both by 5
x = 1.36

A food store makes a 10-pound mixture of peanuts, cashews, and raisins. The mixture has twice as many peanuts as cashews. Peanuts cost $1 per pound, cashews cost $2 per pound, and raisins cost $2 per pound. The total cost of the mixture is $16. How much of each ingredient did the store use to make the mixture?
I know the equations are likely
X = Peanuts
Y = Cashews
Z = Raisins
X + 2Y + 2Z = 16
2Y = X
X + Y + Z = 10
Answers
Answer:
The number of pounds peanuts = x = 4 pounds
The number of pounds cashews = y = 2 pounds
The number of pounds raisins be equal to z = 4 pounds
Step-by-step explanation:
The number pounds of the mixture = 10
Let the number of pounds peanuts = x
Let the number of pounds cashews = y
Let the number of pounds raisins be equal to z
Hence,
x + y + z = 10
The mixture has twice as many peanuts as cashews.
2y= x
= 2y + y + z = 10
= 3y + z = 10
z = 10 - 3y
Peanuts cost $1 per pound, cashews cost $2 per pound, and raisins cost $2 per pound. The total cost of the mixture is $16.
x × $1 + y × $2 × z × $2 = $16
x + 2y + 2z = 16......Equation 2
We Substitute.(2y = x), (z = 10 - 3y)
2y + 2y + 2(10 - 3y) = 16
4y + 20 - 6y = 16
20 - 16 = 6y - 4y
4 = 2y
y = 4/2
y = 2 pounds
z = 10 - 3y
z = 10 - 3(2)
z = 10 - 6
z = 4 pounds
2y= x
2(2) = x
x = 4 pounds
How much of each ingredient did the store use to make the mixture?
The number of pounds peanuts = x = 4 pounds
The number of pounds cashews = y = 2 pounds
The number of pounds raisins be equal to z = 4 pounds

What is the equation for this line?
Answers
Answer:
The equation of the line is y = 2x - 3
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the line, [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept (value y at x = 0)Let us take two points on the line to find its equation
∵ Points (3, 3) and (0, -3) lie on the line
∴ x1 = 3 and y1 = 3
∴ x2 = 0 and y2 = -3
→ Use the rule of the slope above to find m
∵ [tex]m=\frac{-3-3}{0-3}=\frac{-6}{-3}=2[/tex]
∴ m = 2
→ Substitute its value in the form of the equation above
∴ y = 2x + b
∵ b is the value of y at x = 0
∵ y = -3 at x = 0
∴ b = -3
→ Substitute it in the equation above
∴ y = 2x + -3
→ Remember (+)(-) = (-)
∴ y = 2x - 3
∴ The equation of the line is y = 2x - 3

Answers
Answer:
120°
Step-by-step explanation:
A line must add up to 180°.
The sum of angles in a triangle also adds up to 180°.
Step 1: Find measures interior angles.
3x = 180
x = 60°
Step 2: Find measures of exterior angels.
x + 60 = 180
x = 120°
Answer:
120°
Step-by-step explanation:
The sum of all interior angles is found using (n - 2)180
n is the amount of angles inside the polygon (in this case, 3). Plug in 3 for n:
(3 - 2)180 = (1)(180) = 180
There are 3 sides in a triangle. Divide the total (180) with 3:
180/3 = 60
Next, Subtract 60 from 180:
180 - 60 = 120
120 is your exterior angle.
120° is your answer.

Jaden places potatoes with a mass of 0.55 kilograms on a grocer's scale. The spring is displaced by 1.2 centimeters. He then places some onions on the scale that displace the spring by 0.67 cm. What is the mass of the onions (1 kg=9.8 N)? 5.39 kg 3.01 kg 0.67 kg 0.31 kg
Answers
Answer:
.31 kg
Step-by-step explanation:
F=kx
F = the force of the spring
k = the spring constant
x = the spring displacement (stretch or compression)
we also know that 1 kg = 9.8 N which also means that 9.8(kg)=F
let's first find the force of the first problem, which is .55 kg. Using the formula 9.8(kg)=F we can do 9.8(.55)=F which would mean the force is 5.39 N
so 5.39=k(1.2 centimeters)
Now we need to convert centimeters to meters. This would make 1.2 into .012m. Now our problem is 5.39=k(.012)
divide 5.39 by .012 to get 449.17
our k is 449.17
Now for our problem, we are going to find the mass.
Do this by putting what we already know into the problem.
F=449.17(.67 centimeters)
Now we already know we need to convert centimeters to meters which will make our formula F=449.17(.0067m)
This will result in F=3.01 but the problem is asking for mass, not force.
Use the formula 9.8(kg)=F
9.8(kg)=3.01
kg=.31
solution: .31 kg

what is 25 2/3 - 15 1/3 =
Answers
Answer:
10 1/3
Step-by-step explanation:
Convert mixed numbers into improper fractions (whole number × denominator + numerator)
25 2/3 and 15 1/3
25 × 3 + 2 = 75 + 2 = 77
Put the number over the same denominator
77/3
15 × 3 + 1 = 45 + 1 = 46
Put the number over the same denominator
46/3
77/3 - 46/3
They have common denominators so we can simply subtract the numerator values
77 - 46/3
31/3

Convert the numbers to standard from 7.23x10^-10
Answers
Step-by-step explanation:
ok this is search from Google this is right or wrong
Question:
Convert the numbers to standard from 7.23 × 10^(-10)
Answer:
7.23 billionths or 0.000000000723
Explanation:
First, convert the standard form of 10^(-10) to 1 ÷ 10^(10). Thus, the standard operation would be:
7.23 ÷ 10^10 or 7.23 ÷ 10,000,000,000
Hence, you could write it in a reciprocal of a billion, which is a billionth. You could write it in the form of 7.23 billionths or just write it 0.000000000723.

What is the slope of the line graphed below? (5,3) (-5,5)
Answers
Answer:
3
Step-by-step explanation:
but im not sure
Answer:
m = 4/5 (slope)
_____________________________
y = 4/5x - 1 (slope intercept)(y = mx + b)
- 4x + 5y = - 5 (standard form)(Ax + By = C)
y + 5 = 4/5(x + 5) (point slope)(y - y1 = m(x - x1))
Step-by-step explanation:
All you need to do is remember the equation for slope: m = y2-y1/x2-x1
Where your first point is (x1,y1), and your second point is (x2,y2), and m is slope(rate of change : change in y over change in x).
Your first point starts with the smallest x: (-5,-5), then your second point is the greater x: (5,3)
Then just substitute, and solve:
y2-y1/x2-x1 →
3-(-5)/5-(-5) = 3+5/5+5 = 8/10 = 4/5
Extra information:
point slope:
y-y1 = m(x-x1).
Where (x1,y1) is the first point, (x,y) is the second point, and m is the slope. (note: the second point does not have 2 as a subscript so it can be set to slope intercept(y = mx + b) as an equation. This is because you could be given one point, and a slope, and be told to find the other)
Then just plug the coordinates into the equation, and solve for the equation of this line.
Since we already know what the slope is, we can just solve for the general equation given one point:
y-y1 = m(x-x1)
y+5 = 4/5(x+5). (point slope)
y + 5 = 4/5x + 4
-5 -5
____________
y = 4/5x - 1
(slope intercept)
Given slope, another way to find the y intercept is to multiply the current x coordinate by the slope, and add it to the current y value.
given a point (5,3), and a slope of 4/5. The line will be y = slope × x + (y2 - (m × x2)),
y = 4/5 × x + (3 - (4/5 × 5))
y = 4/5x + (3 - 4)
y = 4/5x - 1
