Answer:
In one hour Stephanie earns $1.50 more than Marco
Step-by-step explanation:
w=9h
H is a variable
9×hour= wage
9×15= $135
9×18= $162
157.50-135=$22.50
189-162=$27
27-22.50=4.50
Now cause its per hour we know she earns $4.50 more in 3 hours.
4.50÷3=$1.50
0.2 as a decimal 1/5 as a fraction 20% as a percentage
3/10 as a fraction 0.3 as a decimal and 30% as a percentage
0.75 as a decimal 75% as a percentage 3/4 as a fraction
1.25 as a decimal 125% as a percentage 125/100
Hopes this helps

You do $408.75 - $9.75 = $399
Then you do $399/$33.25 = 12 people.
Answer:
f = 25

Answer:
b = -10.5, a = 3.5
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Find the two numbers their sum is -7 and their difference is 14.
a + b = -7
a - b = 14
<u>Step 2: Solve for a in the first equation</u>
a + b - b = -7 - b
a = -7 - b
<u>Step 3: Find the b in the second equation</u>
a - b = 14
(-7 - b) - b = 14
-7 - 2b + 7 = 14 + 7
-2b / -2 = 21 / -2
<em>b = -10.5</em>
<em />
<u>Step 4: Substitute into a</u>
a = -7 - b
a = -7 - (-10.5)
a = -7 + 10.5
<em>a = 3.5</em>
<em />
Answer: b = -10.5, a = 3.5
