What is the solution to the equation 9(w-4)-7w=5(3w-2)

Answers

Answer 1

Answer: 9(w-4)-7w=5(3w-2)
(9w-36)-7w=15w-10
2w-36=15w-10
add 36
2w=15w+26
subtract 15w
-13w=26
divide by 13
-w=2 so w=-2

Simplify expressions
2=3/4x-7

Answers

Answer: x = 12

Step-by-step explanation:

$2=(3)/(4)x-7$

Add 7 on both sides to get rid of the 7 and isolate x.

$+7+2=(3)/(4)x-7+7$

$9=(3)/(4)x$

Now multiply both sides by $(4)/(3)$ to eliminate it and isolate x.

$((4)/(3))(9)=((3)/(4)x) ((4)/(3))$

$12=x$

Proof;

$2=(3)/(4)x-7\n2=(3)/(4)(12)-7\n2=9-7\n2=2$

Answer:

x = 12

Step-by-step explanation:

2 = 3/4x - 7

2 + 7 = 3/4x

9 = 3/4x

9 × 4x = 3

36x = 3

x = 36/3

x = 12

Translate the sentence into an equation using n as the unknown number. Then solve the equation for n.Two times a number increased by 5 is 15.

a.
2n(5) = 15
n = 1.5
c.
2n + 5 = 15
n = 20
b.
2n + 5=15
n = 5
d.
n + 5 = 15
n = 10

A function is represented by the graph.Complete the statement by selecting from the drop-down menu.

The y-intercept of the function y=−2x+8y is the y-intercept of the function represented in the graph.
A graph with a line running through point (1,6) and point (5, -2)

Answers

Y = -2x + 8 The y intercept of the function is 8

The equation that passes the point ( 1, 6 ) and ( 5, -2)
First solve the slope
M = ( 6 – (-2)) / ( 1 – 5 )
M = -2
At point ( 1,6) solve the y intercept b
Y = mx + b
6 = (-2)(1) + b
b = 8
so the equation is y = -2x + 8
