Find the value of x and the measure of each labeled angle. (8x - 20ºX (5x + 37)

11111nata11111 [884]

According to above figure, the angles (8x - 20)° and (5x + 37)° are pairs of vertical opposite angles, so

8x - 20 = 5x + 37

8x - 5x = 37 + 20

3x = 57

x = 57 ÷ 3

x = 19

14 bugs are crawling on the steps. Some of the bugs are black, and 4 are

docker41 [41]

Answer:

b = 14-4

Step-by-step explanation:

Let the number of black bugs be b

Let the number of green bugs be g

If 14 bugs are crawling on the step, then;

b + g = 14 ....1

If there are 4 green bugs, then g = 4

Substitute g = 4 into the equation

b + g = 14

b + 4 = 14

b = 14 - 4

Hence the sentence that can be required to find the number of black bugs is b = 14-4
