What is the value of x? x+15=2x-40

55 =x

Step-by-step explanation:

x+15=2x-40

Subtract x from each side

x-x+15=2x-x-40

15 = x-40

Add 40 to each side

15+40 = x-40+40

55 =x

x = -25

Step-by-step explanation:

x+15=2x-40

take away x from both sides and take away 40 on both sides to get the like terms on each side

-25 = x

a = 11 : 4

b = 38

c = 1 for every 6

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
