Answer:
b = 35 minutes
Step-by-step explanation:
A)
How long he plays basketball = x
How long he plays volleyball = y
x + y = 95
x = y + 25
B) We will replace (x = y + 25) as x in the first equation
(y + 25) + y = 95
2y + 25 = 95
2y = 95-25
2y = 70
y = 70/2
y = 35
He plays volleyball for 35 minutes everyday

Let the number of baskets be x
Let the number of points be y
32 +3x = y
19 + 4x = y
Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x
y - 3x = 32
- y - 4x = 19
x = 13
Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71
Number of baskets (x) = 13
Number of points (y) = 71
Answer:
Achmed has 7 pencils.
Step-by-step explanation:
Let Achmed have x pencils, then:
Gloria has 2x pencils and Peng has 3x pencils so we have the equation:
x + 2x + 3x = 42
6x = 42
x = 7.
Achmed has 7 pencils.
Answer:
84
Step-by-step explanation:
It's divisible by 3 and 4. 8 is double 4. I did 3*4 which is 12. Then I multiplied it until I found the right answer 12*5=60, 12*6=72, and 12*7= 84.
