If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
Answer:
48.06
Step-by-step explanation:
b^2+c^2=A^2
45+16=42.06
add the extra 6
Answer:
$960
Step-by-step explanation:
Let the original amount be = x
Percentage increase is equal to = 12.5%
final amount = original amount + increase
final amount = x + 0.125x
final amount = 1.125x
final amount = 1080 = 1.125x
and then solve for x
so in the end x is equal to $960
Solve the equation: 1080 = 1.25x
You subtract the numerator from the exponent and you then answer it as a regular exponent. Hope this helps and its not to confusing have a great day and tell me if you need me to clarify this a little more :)
