Hi there!

2(4z - 9 - 7) = 166 - 46
let's make this a little more simpler...

2(4z - 16) = 120

use distributive property.
multiply 2 and 4z , 2 and -16.
8z - 32 = 120

add 32 on both sides to isolate the variable

8z = 152

divide both sides by 8...

z = 19

So your answer is A. 19

Hope this helped!! :)

Answer:

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary

Beth has 5400 in her savings account and withdraws 1/6 of it. The next day she withdraws 2/9 of what remains. How much is left i

faltersainse [42]

1/6 of 5400 is 900 so 5400-900=4500
1/9 of 4500 is 500 so multiply it by 2 and you will get 1000
2/9 of 4500 is 1000,4500-1000=3500

So your answer is 3500

Help it’s easy math but still

I am Lyosha [343]

I think the way that you do is 5/5+3=5/8

5/8*4=2.5 so 2.5 is the answer

Weird question but, whenever you divide by 1/4 or multiply by 4/1, will you always get the same answer.

Answer:

yep

Step-by-step explanation:

when you divide a fraction u can use the KCF method which is basically:

(keep) the first fraction the same

(change) the division sign in the middle to a multiplication sign

(flip) the second fraction

basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways
