Answer:
y = -2x + 9 y =1/9x + 4/9
Step-by-step explanation:
-9/2 = -x -1/2y
-1/2y = x - 9/2
y = -2x + 9
-4 - x = -9y
-9y = -4 - x
y = 1/9x + 4/9
Objective: Solve 2x + 3 = 5x - 42 for x.
Step 1: Subtract 3 from both sides.
2x + 3 = 5x - 42
2x = 5x - 45
Step 2: Subtract 5x from both sides.
2x = 5x - 45
-3x = -45
Step 4: Divide both sides by -3.
-3x = -45
x = 15
Answer:
x = 15
Answer:
D
Step-by-step explanation:
The question states you need a square. That means whatever you do, must leave a square number like 49 or 64
If you add 6 or 7 to 56 you do not get 64 A and C are both wrong.
If you subtract 7 from 56 you get 49 which is a perfect square and all 4 sides will equal 7.
Answer:
