12/20=.6
Thus, move the decimal point two places to the right, and the answer is 60%
Oh this question is kinda tricky. At first glance it’s 1 : 1.5 but notice the units. The model car is 10 inches long and the actual car is 15 feet long.
I think you know where to go from there, but 15 feet * 12 inches = 180 inches.
10 : 180 simplifies to 1 : 18 inches
Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
y = 6x - 11 → (1)
- 2x - 3y = - 7 → (2)
Substitute y = 6x - 11 into (2)
- 2x - 3(6x - 11) = - 7 ← distribute and simplify left side
- 2x - 18x + 33 = - 7
- 20x + 33 = - 7 ( subtract 33 from both sides )
- 20x = - 40 ( divide both sides by - 20 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 6(2) - 11 = 12 - 11 = 1
Solution is (2, 1 )
I will assume it is 2.5% interest rate over 2 years and not per year. If this isn’t the case then let me know.

Well $1250 divided by 100 = $12.50
This is 1%-

-
To make 2.5% we do-> $12.50 x 2.5= $31.25
This makes our interest rate $31.25

To get our total amount.....
$1250 + $31.25 = $1281.25
