Answer:
Step-by-step explanation:
I will assume that you meant: (-3/7)(y-28) - (1/21)y
Using the distributive property of multiplication, we get:
(-3/7)y + (3/7)(28) - (1/21)y
Let's first reudce the middle term. We get: 12
Then we have:
(-3/7)y + 12 - (1/21)y
Here there are two different denominators. We must combine the y terms. The LCD here is 21. Multiplying (-3/7)y by 21/21, we get the equivalent:
-9y
------ + 12 - (1/21)y
21
or:
-9y 21
------ + 12----- - (1/21)y
21 21
Combining the y terms, we get (-10/21)y:
-10y 252
------- + -------- = (1/21)(-10y + 252)
21 21
Answer:
25
Step-by-step explanation:
because if you do 1000 divided buy 25 its 69420 so if you do 69420 divided by 69420 its 1 and 1x1000 its 1000 divided by 54 its 25 so its 25
Answer:
The answer is B) 4
Explanation:
A negative times a negative equals a positive so options A and C are wrong.
-12 divided by 1/4 equals -48
