In 3 hours, at 10 mph, Albert travels 30 miles. In 10 minutes (1/6 hr), while his son overtakes him, he travels 10/6 miles more, placing him at 30 + 10/6 = 190/6 = 95/3 mi.
His son covers 95/3 mi in 1/6 hr, so he's moving at (95/3)/(1/6) = 190 mph.

Write the fraction as the sum of two fractions with the same denominator
grandymaker [24]
1/4 + 1/4 = 1/2

I got 1/2 because if you add 1/4 and 1/4 you'd get 2/4, and when you simplify 2/4 you'd get 1/2.

nydimaria [60]

Answer:

7

Step-by-step explanation:

(15x + 5) and (-2 + 16x) represents the measures of corresponding angles.

Measures of corresponding angles are equal.

Therefore,

- 2 + 16x = 15x + 5

16x - 15x = 5 + 2

x = 7

the answer is 4.5 ft

Step-by-step explanation:

Step-by-step explanation:

Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,

18/x = 8/2

Let's solve for x as required.

We have,

18/x = 8/2

=>Cross multiply:

18 × 2 = 8 × x

36 = 8x

=>Divide both sides by 8

36/8 = x

4.5 = x

x = 4.5 ft
