Answer:

8) x = 4°

9) $7176.53

10) 22

Step-by-step explanation:

8) The sum of all three interior angles of any triangle = 180°

11x + 25x + 9x = 180°

45x = 180°

divide both sides of the equation by 45:

x = 4°

9) ($6500 x 1.02) = 6630 x 1.02 = 6762.60 x1.02 = 6897.85 x 1.02 = 7035.81 x 1.02 = 7176.53

10) (2/5)(55) =110/5 = 22

Simplify each of the following ratios.<br>e) 2/3 : 3/2 : 5/8​
Snezhnost [94]

Answer:

32/45

Step-by-step explanation:

2/3 : 3/2 : 5/8

Remember, a ratio and a fraction are both division. Therefore you can rewrite the problem like so:

2/3 ÷ 3/2 ÷ 5/8

Dividing fractions is the same as multiplying them by the reciprocal.

2/3 * 2/3 * 8/5

Now simplify:

32/45

32 and 45 have no common factor, hence the final answer is 32/45
