Answer:
1. 15 (A)
2. 12 (G)
Step-by-step explanation:
1. We can make an equation out of this...
3x+3=48
x is the age of Geoff which is what we are trying to find out
We have to add 3 to both sides of the equation
3x+3=48
-3 -3
________
we end up with 3x=45
we then have to divide 3 by both sides because its the opposite of
multipling
3x=45
_____
3
we get x=15
2. We can write a problem statement
(2 x 9)-6=?
multiply 2 and 9 <u>FIRST</u>
18-6=?
your answer is 12
Your Welcome! Have a great rest of your day! :)
No i dint think it is 2×8-4=12 and 8 is not equal to 12 :)
Answer:
answer is 9
Step-by-step explanation:
1st method: Proportion
15/100 = n/60
cross-multiply to get:
100n = 900
n = 900/100
n = 9
2nd method: Convert % to Decimal and Multiply
.15 × 60 = 9
This has to do with place value.....the 3, since it is on the left of the decimal, is a whole number. The last number (6) is in the hundredths place..
so it is 3 56/100 which reduces to 3 14/25
