Mathematics
1 answer:
chubhunter [2.5K]3 years ago
5 0

Answer:

130

Step-by-step explanation:

The two angles add up to 180 since they form a straight line

4y-50 + 3y+55 = 180

Combine like terms

7y +5 = 180

Subtract 5 from each side

7y-5+5 = 180-5

7y = 175

Divide each side by 7

7y/7 =175/7

y =25

The obtuse angle  is greater than 90 degrees

3y+55

3(25) +55

75+ 55

130

Tickets to the movies cost $24 for 1 adult. The price of 1 child was 2/3 of that price. How much did a family with 2 adults and
Neko [114]
Tickets are 24$ for 1 adult.

Two thirds of 24 will be the price of 1 child. Divide 24 by 3 and you get 8. Since 8 is 1/3 of 24, 16 would be 2/3 of 24.

So the price for 1 child is 16$.

2 adults and 2 children is 24+24+16+16

The family had to pay a total of $80

How to do gcf vs lcm
tangare [24]
GCF stands for greatest common factor so if u have a problem like let's say, "What is the gcf of 36 and 90?" all u do is go down your multiples table and write them all down till 36 you will get 9 and if u take 10×9 it equals 90. For LCM all you do is go down your multiples table and find the least number that is the same with each other.
