Using proportions, it is found that the family will drive 482.8 km on the new route.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:
D = 1.25 x 240 = 300 miles.
Since there are are approximately <u>48.28 kilometers in 30 miles</u>, and 300/30 = 10, the distance in kilometers is given by:
D = 48.28 x 10 = 482.8 km.

Answer:
the answer is 9
Step-by-step explanation:
why it 9 Add '2.7' to each side of the equation.
-2.7 + 2.7 + 0.3x = 9 + 2.7
Combine like terms: -2.7 + 2.7 = 0.0
0.0 + 0.3x = 9 + 2.7
0.3x = 9 + 2.7
Combine like terms: 9 + 2.7 = 11.7
0.3x = 11.7
Divide each side by '0.3'.
x = 39
Simplifying
x = 39
Answer:
see below
Step-by-step explanation:
m+6/3 = -8
Simplify the fraction
m+2 = -8
Subtract 2
m+2-2 = -8-2
m = -10
or
(m+6)/3 = -8
Multiply each side by 3
m+6 = -8*3
m+6 = -24
Subtract 6
m+6-6 = -24-6
m = -30
.8 percent of 200 is 1600 becaus 2000* .8=1600
