ursula earns $9 per hour. to write an expression that tells how much money ursula earns for h hours, josh wrote 9\h. sarah wrote 9h. whose expression is correct and why

Answers

The important information's already given in the question can be used to find the correct answer.
In 1 hour Ursula earns = 9 dollars
So
In h hours Ursula earns = (9/1) * h dollars
= 9 * h hours
= 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h.I hope you are satisfi3ed with the answer and theexplanation that I have provided. You can use this procedure for solvingsimilar problems.

Sarah is correct because if Ursula is earning $9 per hour then every hour you can add 9. Lets say h=2 then you would multiply 9*2 to get how much she spent. Josh is incorrect because dividing would subtract the amount of money every our.

What is the solution of −81=b6 ?A. b = −486
B. b = −75
C. b = 13.5
D. b = 486

Answers

We have to isolate b to be alone.
Soooo first we divide both sides by 6

-81 = b6
÷6 = ÷6 The right side cancels out and gets the b alone. While we solve the right side of the equal sign.
-81 ÷ 6 = -13.5
So this means we isolated b alone!
b = -13.5

Our final answer is..
b = -13.5

Math. :)Question: 1.1W + 2.1 = 5.4
Answer: W = 2.2

Is the answer correct? How do you check the answer?

Thank you in advance!!

Answers

$\sf~W+2.1=5.4$

Subtract 2.1 to both sides:

$\sf~W=3.3$

This is one-step equation.
$W+2.1=5.4 \n W+2.1-2.1=5.4-2.1 \n W=3.3 \n CHECK- \n 3.3+2.1=5.4$
