a-7=3(b+2)
1. Simplify/Combine like terms
a-7=3b+6
2. Remove a variable
a-7-a=3b+6-a
7=2b+6
3. Isolate the variable
7-6=2b-6
1=2b
4. Divide
1/2=2b/2
b=1/2
1/2g?
I think I can help you what unit is that? And is that algebra
Answer:
S
usan will have 25% more books than Michael
Step-by-step explanation:
First we have to calculate how many books Susan has
x = Susan's books
50% = 50/100
x = 40 + 40 * 50/100
x = 40 + 20
x = 60
y = Michael's books
y = 40 + 8
y = 48
60 > 48
S
usan will have more books than Michael
To know the percentage of more that susan will have we have to divide the quantity of susan's books by michael's
60/48 = 1.25
To find the percentage we multiply it by 100 and subtract 100
1.25 * 100 - 100 =
125 - 100 = 25%
I might be wrong but Im sure it's -5
