Answer:
y = -7 and x = -36
Step-by-step explanation:
x - 4y = -8
5y - 1 = x
→ Substitute 5y - 1 into x - 4y = -8
5y - 1 - 4y = -8
→ Simplify
y - 1 = -8
→ Add 1 to both sides
y = -7
→ Substitute y = -7 into 5y - 1
( 5 × -7 ) - 1 = -36
10.71% is 9% of 84.
So 10.71% is the answer.
Answer:
Step-by-step explanation:
The most important part of this question is the estimation. That means you round either up or down to get whole numbers.
You can make - 37.44 either - 40 or - 35
You can make 4.8 into 5
So the answer should lie between -40/5 = - 8
or
The answer should be between - 35/5 = - 7
Use your calculator to check it.
-37.44 ÷ 4.8 = - 7.8
This skill is very handy when shopping or writing a test. It you get an outrageous answer like - 21.44 you know you have done something wrong.
