IM GONNA GIVE 69420 COOKIES TO THE PERSON WHO GETS TRHIS QUESTION CORRECT
Kisachek [45]

Answer:

z = 104 degrees

y = 34 degrees

Step-by-step explanation:

The angle to the left of z must be 76 Degrees as it’s an alternating angle with the 76 Degree angle on the left. It must combine with z to form 180 degrees so it’s 104 degrees.

The angle below z must also combine with z to give 180 degrees so it’s 76.

5y - 94 = 76

5y = 76 + 94

5y = 170

Y = 170/5

y = 34

Help please! 40 points
sattari [20]

Answer:

11 1/2 quarts

Step-by-step explanation:

We need to add the quarts of paint

2 2/4 + 4 3/4 + 4 1/4

Since they all have the same denominator for the fraction, we add the whole numbers

2+4+4 = 10

And the fractions

2/4 + 3/4+ 1/4 = 6/4

This is bigger than 1

6-4 =2 so we have 1 +2/4

10 + 1 + 2/4

11 2/4

We can simplify 2/4 because the top and bottom can be divided by 2

11 1/2 quarts
