Find x+y ....................

Mathematics
1 answer:
ANEK [815]3 years ago
4 0

Answer:

x + y = 170

Step-by-step explanation:

360 = 110 + x + y + 80

x + y = 360 - 110 - 80

x + y = 170

To understand this, take scissors and look at the angles how they change when you change the angle... there are always just TWO different angles and each of the angle has its exact counterpart on the opposite side. Now look again at this illustration and you will get it!

Another information, sum of all the angles inside of any rectangle is always 360 degrees!

A scooter travels 30 feet in 2 seconds at a constant speed.
Sever21 [200]

Answer:

The scooter travels 15 feet in 1 second

The scooter travels 45 feet in 3 seconds

The scooter travels 60 feet in 4 seconds

The scooter travels 75 feet in 5 seconds

Step-by-step explanation:

First, let's find the number of feet the scooter travels in 1 second

(30 : 2) ÷ 2 = 15 : 1

Now that we have the unit rate, we can easily find the answers to the other questions.

(15 : 1) x 3 = 45 : 3

(15 : 1) x 4 = 60 : 4

(15 : 1) x 5 = 75 : 5

I Hope That This Helps! :)

What’s the answer for a, and b, and how would you solve it?
xxTIMURxx [149]

Answer:

a) negative

b) -7/6

Step-by-step explanation:

The x value increased, but the y value decreased so the line goes down and has a negative slope

(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line

(4-(-3))/(-1-5)=7/-6
