Step-by-step explanation:
bowling balls without holes = 77 and 35%
find: how many bowling balls in the store?
let x be the total
its a ratio and proportion:
<u> 77 </u> = <u> x </u>
35 100
cross multiply:
35 (x) = 77 (100)
x = 7700 / 35
x = 220 ------>> total number of balls in the store
Answer: 40 degrees
Step-by-step explanation:
180-140=40
You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
