You need to use the distributive property. So you take the -9 from outside the parentheses and multiply itself by the numbers inside.

Answer: <span>C) (3, 3.9)(65, 84.5)(24, 31.2)
</span>
Explanation:

Ou choice is C) and we just need to prove that 17:22.1 = 3:3.9. First, we will change the ratios into fractions so that

$\boxed{ \frac{17}{22.1} = \frac{3}{3.9}}$

To prove the above equation we use cross multiplication so that

17(3.9) = 3(22.1)
66.3 = 66.3

Which is a true equation. Therefore, 17:22.1 = 3:3.9.

A car travels for 4(t+3) hours at a constant speed of 10(t+3) km/h. If the total distance travelled by the car is 810 km, find t

IRISSAK [1]

Speed of the car is 45 km/h

Step-by-step explanation:

Step 1: Find the distance traveled by the car in the first case.

Given that the speed of the car = 10 (t + 3) km/h

Time taken = 4 (t + 3) hours

Distance = Speed × Time

= 10 (t + 3) × 4 (t + 3) = 40(t + 3)² km

Step 2: Equate the distance of 810 km with the distance that has been calculated above, since both are the same.

⇒ 810 = 40 (t + 3)²

⇒ (t + 3)² = 81/4

⇒ t + 3 = √81/4 = 9/2

⇒ t = 9/2 - 3 = 3/2 = 1.5

Step 3: Find the speed of the car.

Speed = 10 (1.5 + 3) = 10 × 4.5 = 45 km/h

The projected number of employed writers and authors in 2016 is 153,000. 12.4% of those will have some college experience but no

goblinko [34]

12.4% of 153,000 : some college, no degree
0.124(153,000) = 18,972

84.1% of 153,000 : bachelor's degree or higher
0.841(153,000) = 128,673

128,673 - 18,972 = 109,701 <==
