Which set of values could be the side length of a 30-60-90 Triangle!
-4.8 (6.3x-4.18)=-58.56 what is x?
Answer:
x = 2.825
Step-by-step explanation:
-4.3(6.3x + -4.18) = -58.56
-4.3(-4.18 + 6.3x) = -58.56
(-4.18 * -4.3 + 6.3x * -4.3) = -58.56
(17.974 + -27.09x) = -58.56
17.974 + -27.09x = -58.56
17.974 + -17.974 + -27.09x = -58.56 + -17.974
0.000 + -27.09x = -58.56 + -17.974
-27.09x = -58.56 + -17.974
-27.09x = -76.534
x = 2.825175341

Answer/Step-by-step explanation:
a. 3x + 13 = 12x - 2x
Add like terms
3x + 13 = 10x
3x = 10x - 13 (subtraction property of equality)
3x - 10x = - 13 (substraction property of equality)
-7x = -13
-7x = -13/-7 (division property of equality)
x = 13/7
b. 6j - 12 + 4j - 8 = 10
Add like terms
6j + 4j - 12 - 8 = 10
10j - 20 = 10
10j = 10 + 20 (addition property of equality)
10j = 30
10j/10 = 30/10 (division property of equality)
j = 3
c. 10y - 4y = 14 + 2y - 3y
Add like terms
6y = 14 - y
6y + y = 14 (addition property of equality)
7y = 14
7y/7 = 14/7
y = 2
d. 4p + 8 - 3p = 33
Add like terms
4p - 3p + 8 = 33
p + 8 = 33
p = 33 - 8 (subtraction property of equality)
p = 25

what is 0.34 round to the nearest tenth
Answer:
0.3
Step-by-step explanation:
We use the following rules to round 0.34 to the nearest tenth:
A) If the last digit in the fractional part of 0.34 is less than 5, then simply remove the last the digit of fractional part.
B) If the last digit in the fractional part of 0.34 is 5 or more and the first digit in the fractional part is less than 9, then add 1 to the first digit of the fractional part and remove the second digit.
C) If the last digit in the fractional part of 0.34 is 5 or more and the first digit in the fractional part is 9 then add 1 to the Integer part and make the fractional part 0.
With 0.34, rule A applies and the answer is: 0.3

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-5x + 2y = 9
y = 7x
Step 2: Solve for x
Substitution
Substitute in y: -5x + 2(7x) = 9Multiply: -5x + 14x = 9Combine like terms: 9x = 9Isolate x: x = 1Step 3: Solve for y
Define original equation: y = 7xSubstitute in x: y = 7(1)Multiply: y = 7Answer: x = 1 and y = 7
Step-by-step explanation:
first you substitude y for 7x
-5x + 2(7x) = 9
then you distribute
-5x + 14x = 9
then you combine like terms
9x = 9
then you divide both sides by 9
x = 1
then you subsitute the x value in the other equations
y = 7(1)
meaning y = 7

Which statement is true about the graphs of the two lines y=-x+2 and y=-x- ?
O The lines are perpendicular to each other because - and - are opposite reciprocals of each other.
The lines are perpendicular to each other because 2 and - 1 are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 3 are not opposite reciprocals of
each other.
Answer:
The correct option is Option C
Step-by-step explanation:
We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]
The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]
In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)
In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)
The opposite reciprocal of -4/5 is 5/4
So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.
If the lines are parallel there slope must be same. Hence lines are not parallel as well.
So, The correct option is Option C
Answer:
c

The total cost of bag and an umbrella is Rs 2000.If the cost of the bag is Rs 1000 less five times the cost of the umbrella ,find the cost of each of these two items.
Answer:
The bag costs 1500, while the umbrella cost 500
Step-by-step explanation:
Let the cost of the bag be b and the cost of the umbrella be u
Total cost is;
b + u = 2,000 •••••(i)
From the second part of the question;
b = 5u-1000 ••••••(ii)
Substitute ii into i
5u-1000 + u = 2000
6u = 2000 + 1000
6u = 3000
u = 3000/6
u = 500
To get b, substitute the value of u into equation ii
b = 5(500)-1000
b = 2500-1000
b = 1500

In the equation y=mx, how do you find m on a graph?
Answer:
m is the slope of the equation y=mx+b. TO find the slope you look at the y intercept of the graph, b, and from that point find how much up/down and to the right/left you need to go. For example from point 0, 4, the y intercept, to another point on the graph (any point on the line would work) 2, 8 , I need to go up 4 units and to the right 2 units. The slope is 4/2 or just 2.'
If this is too confusing just find two points on the line in a graph and folow this equation: y2-y1 / x2-x1
where y2 is the y value of the second point, y1 is the y value of the first point, x1 is the x value of the first point and x2 is the value of x in the second point
Step-by-step explanation:
Answer:
In the equation y=mx+b, m is the slope. The formula for slope is [tex]\frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex], so to solve find any two points on the graph and plug them into the formula. You could also count the difference, remember that slope is the change in y over the change in x. For example, if y increases by 3 units and x increases by 2 units then the slope is 3/2.

Savelot offers two types of baseballs bats the wood bat sell for 24$ and the metal bats sell for 30 in one day save lots sold 23 base ball bats these recipts for those bats totaled $606 how many of each type of bat was sold
Answer:
Step-by-step explanation:
Let us represent
Let the wood bat = w
Let the base ball bats = b
Savelot offers two types of baseballs bats the wood bat sell for 24$ and the metal bats sell for 30 in one day save lots sold 23 base ball bats these recipts for those bats totaled $606 how many of each type of bat was sold
System of Equations
w + b = 23.... Equation 1
b = 23 - w
24w + 30b = 606..... Equation 2
We substitute:30 - w for b
Hence:
24w + 30(23 - w) = 606
24w + 690 - 30w = 606
24w - 30w = 606 - 609
-6w = -84
w = -844/-6
w = 14 wood bats
b = 30 - 14
b = 16 base ball bts
what is the area of the figure below
A: 88in2
B: 48 in2
C: 68 in2
B:43in2
Answer:
The correct answer is C, 68in².
Answer:
68
Step-by-step explanation:
The are of the square is 3*3 = 9
Since we have two squares we need to mulitply by 2
9*2 = 18 is the total area of the squares
if you draw a line from the one square to the other you make a rectangle in the middle
the are of the rectangle is 10*3 which is 30
Two triangle has appared as we draw the line from one square to the other square.
The height of the traingle is (7 - 3)/2 which is 2
(2*10) / 2 = which is 10
Since we have 2 triangle we get result as 2*10 = 20
20+30+18 = 68
