Answer: The number is -20
Step-by-step explanation:
Take each part of the sentence and write what it is telling us:
3 less than the <u>quotient of a number and 5</u> is -7
The <u>quotient of a number and 5</u> is (X/5), where X is the "number."
<u>3 less than</u> is (X/5) - 3
<u>is -7 </u> is = -7
Therefore:
3 less than the quotient of a number and 5 is -7 is: (X/5) - 3 = -7
---
(X/5) - 3 = -7
(X/5) = -4
X = -20
===
See if this works:
3 less than the quotient of <u><em>-20</em></u> and 5 is -7
(-20/5) = -4
Three kless than -4 is -7: It works
Answer:
1.) is 78 2.) is 4
Step-by-step explanation:
Standard form: ax+by=c
With standard form there are a few rules One being ax and by cannot be fractions. Two being ax has to be positive.
Now ill explain the problem.
y=-1/2x-5 ↔ You will need to multiply the whole problem by 2 which will leave you will this 2y=-2x-10
Next you will need to move x over to the y side which will look like this 2x+2y=-10 (your answer)
Now you might be asking where the - went that was in front of the x term. Another rule is when you move across the equal sign you change the sign.
