25 × x = 45
or 25÷100 × x= 45
multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25
therefore, x = 180
( if you use a calculator simply enter 45×100÷ 25)
Answer:
<u>C and D</u>
Step-by-step explanation:
<u>D.</u> A negative times a positive gives you a negative, so the first 2 fractions will still be negatives after they get out of the parenthesis
<u>C.</u> The 4/7 and -4/7 cancel out
Answer:
Step-by-step explanation:
C. -11<x<-4
|-2x-15|<7 split into possible cases
- 2x - 15 < 7, - 2 x - 15 > 0
-(- 2x - 15 ) <7, -2x - 15 < 0 solve the inequalities
x>-11, x < -15/2
x< -4, x> -15/2 Find the intersections
[ -11, -15/2 ]
-15/2, -4] Find the union
[-11, -4 ] Simplify
-11<x<-4
2 6/7 ÷ 2/3
= 20/7 ÷ 2/3
20/7 × 3/2
= 60/14
reduce to it's lowest term
30/7 = 4 2/7
