Mathematics
1 answer:
shtirl [24]3 years ago
6 0

Answer:

x = 18 and y = 11

Step-by-step explanation:

The angles 6x - 16 and 92 are vertical angles and congruent, thus

6x - 16 = 92 ( add 16 to both sides )

6x = 108 ( divide both sides by 6 )

x = 18

Angles 8y and 92 form a straight angle and are supplementary, thus

8y + 92 = 180 ( subtract 92 from both sides )

8y = 88 ( divide both sides by 8 )

y = 11

At Billy's school, 80 students come to school by bicycle or by car. Together, the vehicles they arrive to school in have 270 whe
Anna35 [415]

Answer:

x = number of bicycles = 35

y = number of cars = 55

Step-by-step explanation:

Let

x = number of bicycles

y = number of cars

x + y = 80 (1)

2x + 4y = 270 (2)

From (1)

x = 80 - y

Substitute x = 80 - y into (2)

2x + 4y = 270 (2)

2(80 - y) + 4y = 270

160 - 2y + 4y = 270

- 2y + 4y = 270 - 160

2y = 110

y = 110/2

y = 55

Substitute y = 55 into (1)

x + y = 80 (1)

x + 55 = 80

x = 80 - 55

x = 35

x = number of bicycles = 35

y = number of cars = 55
