Answer:
<h2>220</h2>
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:
Obi's age is 18 and Oba's age is 9
Step-by-step explanation:
Let Obi's age be x and Oba's age be y
<u><em>Condition 1:</em></u>
x = 2y -----------(1)
<u><em>Condition 2:</em></u>
(x-4) = 3(y-4)
=> x -4 = 3y-12
=> x - 3y = -9 -----(2)
<u><em>Putting eq (1) in (2)</em></u>
2y - 3y = -9
=> -y = -9
=> y = 9
Now,
x = 2y
=> x = 2(9)
=> x= 18
Answer:
48
Step-by-step explanation:
Let x be the total number of M&Ms in the bag.
0.75x = 36 because 75% of the M&Ms are red and there are 36 red M&Ms.
We can divide both sides by 0.75, getting x = 48.
Therefore, there are 48 M&Ms in the bag.
The answer would be C, because 5(2)=10 and 5+5=10. Hope this helped! :)
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
