Answer:
26 boys
Step-by-step explanation:
26 boys
3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)
(1) - (2) => 2f = 4 => f = 4/2 = 2
From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12
Therefore, f = 2 and g = 12
Distance = speed * time
d = 65.2 * 1.8
d = 117.36 miles <==
Answer:
A: [2(200-x)]/3 B: 31.33333...
Step-by-step explanation:
A: Algebraic expression:
Let's say average = x
So the expression is [2(200-x)]/3
You have to take average away from 200, which is 200-x, you have to multiply that whole expression by 2, and then divide everything by 3.
B: Plug in 153 for x:
2(200-153)/3 and then just solve algebraically
=2(47)/3
=94/3
=31.33333...
