X = ?, y = ?;
2 x - 70° = x + 30°
2 x - x = 30° + 70°
x = 100°
x + 30° + 5 y = 180°
130° + 5 y = 180°
5 y = 180° - 130°
5 y = 50°
y = 50° : 5
y = 10°
Answer: C ) x = 100, y = 10
Answer:20 is 50% of 1000
Step-by-step explanation:When 1000 is divided by 20,it gives 50.
It isn’t because when there is no addition in the equation the y intercept is 0
Answer:
<h2>z = 18</h2>
Step-by-step explanation:

<u>Answer:</u>
16 men
20 women
<u>Step-by-step explanation:</u>
We are given that the ratio of the number of men to the number of women on a bus was 2:3 at a bus stop.
So assuming x to be the number of persons (male or female), we can write it as:

When 4 women got off the bus, the ratio changed to 4:5.

Solving it to find x:




So, number of men on the bus =
= 16
and number of women on the bus at the end =
= 20
