Answer:
h = 590
Step-by-step explanation:
To find x, rearrange the equation to where h is on its own side.
<u>Rearranged equation:</u>
Since 169 added to h was to find 769, 169 subtracted from 759 represents h.
<u>Solve:</u>
590 = h.
Answer:
x=6
Step-by-step explanation:
you need to get x alone so you divide by 3 on both sides
hope this helps!!! :)
example:
3x/3= 18/3
x=6
Answer:
25
Step-by-step explanation:
Each of the 16 "ratio units" representing all 80 dancers must stand for ...
(80 dancers)/(16) = 5 dancers
Then 5 "ratio units" representing seventh-grade dancers will stand for ...
5 × 5 dancers = 25 dancers
___
Another way to figure this is to write the proportion ...
(seventh-grade dancers)/(all dancers) = 5/16
seventh-grade dancers = (all dancers)×(5/16) = 80×5/16
seventh-grade dancers = 25
Make a proportion
81/30 = x/600
600/30 = 20
x/81 = 20
x = 1620
Solution: 1620 calories
