Write an equation representing the pound of clay, c, that jamal from the example needs to make b bowls.
explain how to find the amount of clay jamal needs to make 8 bowls.
Answer:
8=2/3c
Step-by-step explanation:
Each bowl requires 2/3 pounds of clay
To make 8 bowls, Jamal needs 5 1/3 pounds of clay
1. The equation to represent amount is, x= b*c
2. Amount of clay Jamal needs to make 8 bowls is 8c.
What is equation?A mathematical statement that is made up of two expressions connected by an equal sign.
let the amount of clay be x.
The number of bowls be b and c is pounds of clay.
So, Total cost
x= b * c
Now, if number of bowls are 8 then
x= 8*c
x=8c
So, the amount of clay Jamal needs to make 8 bowls is 8c.

Complete the ordered pair so that it is a solution of 2/3x + y - 1 = 0. (-6, ___) 3 4 5
Answer:
(- 6, 5 )
Step-by-step explanation:
Substitute x = - 6 into the equation and solve for y
[tex]\frac{2}{3}[/tex] (- 6) + y - 1 = 0 , that is
- 4 + y - 1 = 0
y - 5 = 0 ( add 5 to both sides )
y = 5
Then solution is (- 6, 5 )
- 4x + 14 = -2(2x + 7)

Find the slope of the line that passes through (19, -9) and (70, 68).
Simplify your answer and write it as a proper fraction, improper fraction, or integer. Quick please
Answer:
The slope of the line would be 77/51 or 1.5098 if you convert it.
Step-by-step explanation:
Slope is rise over run so you find the difference between the Ys which is 77 and that's your rise so it's the top. You then find the difference btween the Xs and its 51 and that's your run so it's the bottom.
Im not sure how to do this
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then then corresponding sides are in proportion , that is
[tex]\frac{NP}{ST}[/tex] = [tex]\frac{NM}{SR}[/tex] , substitute values
[tex]\frac{x}{25}[/tex] = [tex]\frac{18}{30}[/tex] ( cross- multiply )
30x = 450 ( divide both sides by 30 )
x = 15
Similarly
[tex]\frac{UT}{QP}[/tex] = [tex]\frac{NM}{SR}[/tex] , that is
[tex]\frac{y}{15}[/tex] = [tex]\frac{18}{30}[/tex] ( cross- multiply )
30y = 270 ( divide both sides by 30 )
y = 9
The similarity ratio is the ratio of corresponding sides , that is
[tex]\frac{NM}{SR}[/tex] = [tex]\frac{18}{30}[/tex] = [tex]\frac{3}{5}[/tex]
SRUT is [tex]\frac{3}{5}[/tex] of NMQP

find tge equation of the line
Answer:
y = -2x + 9 or y = 9 - 2x
Step-by-step explanation:
First find the gradient
Pick two points on the graph, (4, 1) and (1,7)Find the change in y (7 - 1 = 6)Find the change in x (1 - 4 = -3)Divide the change in y by the change in x = 6 ÷ -3 = -2The gradient is -2: y = -2x + cNext, look at where the line intercepts (goes through) the y-axis: 9
The equation of the line is y = -2x + 9
Tip: The gradient is negative because the line is going downwards from left to right; if the line was going upwards, the gradient would be positive.

For the pair of similar triangles, find the value of x.
2x8
x+8
24
The value of x is a
(Simplify your answer. Use a comma to separate answers as needed.)
Answer: x = 22
Step-by-step explanation:
Compare the 2 triangles
[tex]\frac{2x-8}{24} = \frac{45}{x+8}[/tex]
Cross multiply
(2x-8) (x+8) = 45 x 24
2x^2 + 16x - 8x - 64 = 1080
2x^2 + 8x - 64 - 1080 = 0
2x^2 + 8x - 1144 = 0 ---> divide by 2
x^2 + 4x - 572 = 0
(sum and product)
x^2 - 22x + 26x - 572 = 0
x(x - 22) + 26(x - 22) = 0
(x + 26) (x - 22) = 0
x + 26 = 0
x = -26
x - 22 = 0
x = 22
