The answer is G. I know because, 1.75 * 3 (slices of pizza) = 5.25.
13.75 - 5.25 = 8.5
8.5 / 4 (hot dogs) = 2.1 (price per hot dog)
We can apply this to Sarah by saying
2 * 1.75 = 3.5
3 * 2.1 = 6.3
Added equals 9.8 or 9.75 (Sarah's total)
Correct me if I am wrong hope this helps:)
4 × ( x + 4 ) = 3 × ( 3 + 5 )
4 × ( x + 4 ) = 3 × 8
Divide both sides by 4
x + 4 = 3 × 2
x + 4 = 6
Subtract both sides 4
x = 2
Answer:
z = 15
Step-by-step explanation:
The sum S of the interior angles of a regular polygon is given by the formula
S = (n-2) x 180 where n is the number sides
Here n = 9
So S = (9-2) x 180 = 7 x 180 = 1,260
There are 9 interior angles and each angle is (5z + 65)
So the sum of all 9 interior angles = 9 (5z + 65)
= 45z + 585
Set these equal to each other and solve for z
45z + 585 = 1260
45z = 675
z = 675/45 = 15
$900+ $288( interest after 8 years)= $1, 188( total balance)
