Answer:
36 laps Ronnie swim during practice .
Step-by-step explanation:
Let us assume that the laps that Ronnie swims be x .
Let us assume that the laps that Jackie swims be y .
As given
For every 3 laps that Jackie swims, Ronnie swims 4 laps.
i.e
3 × laps that Ronnie swims = 4 × laps that Jackie swims
3 × x = 4 × y
3x = 4y
Equation becomes
x + y = 63
Thus by using 3x = 4y .

Thus

4x + 3x = 63 × 4
7x = 252
x = 36
Put the value of x in the equation x + y = 63
36 + y = 63
y = 63 - 36
y = 27
Therefore the 36 laps Ronnie swim during practice .

Answer:
144 push-ups
Step-by-step explanation:
hii
assuming they did the same amount of pushups every day:
112 pushups in 14 days
112p : 14d
xp : 18d
14 ÷ 7 =2
2 × 9 = 18
do the same do the pushups ( ÷7 and ×9)
112 ÷ 7 = 16
16 ×9 = 144
should be 144 pushups
hope this helps :)
