Answer:
Step-by-step explanation:
<u>Given</u>
- x : y = 2 : 5, y is 80% of z
<u>Rearranging the ratios:</u>
- x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5x
- y is 80% of z ⇒ y = 0.8z
<u>Comparing the values of y:</u>
- 2.5x = 0.8z
- x/z = 0.8/2.5
- x/z = 0.32
- x/z = 32/100
- x/z = 8/25
- x : z = 8 : 25
Answer:
1/5
Step-by-step explanation:
Perpendicular means the negative reciprocal the reciprocal of - 5 is -1/5 add the negative to get 1/5
Answer:
I think 3 have more, but I am not 100 percent
Answer:
C(5, 4)
Step-by-step explanation:
The rule for a reflection over the y -axis is (x,y)→(−x,y) .
Answer:
A:-4
Step-by-step explanation:
If you simplify 9(2x+1)<9x-18 you will get 9x<-27. That will mean x<-3 and the only answer for something less than -3 is -4.
If the answer was right, please put 5 stars.
