ZEFG and ZGFH are a linear pair, mZEFG = 3n+ 21, and mZGFH = 2n + 34. What are mZEFG and mZGFH?
marysya [2.9K]

Answer:

The answer is below

Step-by-step explanation:

∠EFG and ∠GFH are a linear pair, m∠EFG = 3n+ 21, and m∠GFH = 2n + 34. What are m∠EFG and m∠GFH?

Solution:

Two angles are said to form a linear pair if they share a base. Linear pair angles are adjacent angles formed along a line as a result of the intersection of two lines. Linear pairs are always supplementary (that is they add up to 180°).

m∠EFG = 3n + 21, m∠GFH = 2n + 34. Both angles form linear pairs, hence:

m∠EFG + m∠GFH = 180°

3n + 21 + (2n + 34) = 180

3n + 2n + 21 + 34 = 180

5n + 55 = 180

5n = 125

n = 25

Therefore, m∠EFG = 3(25) + 21 = 96°, m∠GFH = 2(25) + 34 = 84°

1) stacey is selling tickets to the school play the tickets are $8 for adults and $5 for children . she sell twice as many ticke
Lapatulllka [165]
2) 25/48 All you do is multiply both.
1) she sold 5 children and 10 adult. 5 *5 equals 25. You double 5 to get twice as many tickets for adults and get 10. 8 *10 equals 80. 80 + 25= $105

You are converting the numbers to a word problem.

1. 5+x = the number five plus x

2.  5-x= the number 5 minus x

3. 5x= five times x

4. 5/x= five divided by x

5. three-fourths of x plus 2

6. two minus three-fourths of x

7. 3 times x plus 10

8. ten times x plus three

Please help! Will mark brainliest!
Anastaziya [24]

Answer:

5

Step-by-step explanation:

I am not quite sure if this is correct.

first I figured out how many minutes per 1 mile: 24

then I figured out how exactly much time 1.5 hours is: 1 hour and 12 minutes. then I subtracted that from 2 hours, knowing that 1.5 hours is 3 miles, I found that there was only 48 minutes remaining in that hour, which would be 24×2, aka 2 miles. so the final answer would be 5 miles, sorry for the run-on sentence. Yet again, I am not quite sure if this is right-
