C. Multiply both sides by 9/5.
C = 5/9(F – 32)
We want to isolate F, which means we need to get F alone.
The quantity in the parentheses is multiplied by 5/9. We need to do the opposite, or multiply by the reciprocal to isolate the parentheses
9/5 C = 9/5* 5/9(F – 32)
9/5 C = F-32
This is the first step in isolating, or solving, for F
Answer:
x = -1
y = 1
Step-by-step explanation:
x = 6y - 7
4x + y = -3
substitute x for 6y - 7 in the second equation
4x + y = - 3
4(6y - 7) + y = -3
open the parenthesis
24y - 28 + y = -3
combine like terms
25y - 28 = -3
add 28 to both sides of the equation
25y - 28 + 28 = -3 + 28
25y = -3 + 28
25y = 25
y = 1
now that you know y is 1, substitute it back into either equation
x = 6y - 7
x = 6 * 1 - 7
x = 6 - 7
x = -1
Answer:
I believe it takes : 3 jumps of 1/5 to reach 15.
Step-by-step explanation:
Hope my answer has helped you!
Let's look at the way each of these attempts to simplify our expression.
Answer A simply mulltiplies the 4 and the 7 to get 28. <em>This is the correct answer</em>.
The reason you can't just do squaring (to the power of 2) and then go to the power of x later is because you would write that as
, not
.
