Answer:
240 students are boys
Step-by-step explanation:
20% of 300 = 60
300 - 60 = 240
Answer:
H - Triangle Z, Triangle X, Triangle Y
Step-by-step explanation:
Triangle X area = rad(66.5) cm^3 ≈ 8.155cm^3
Triangle Y area = 8.15cm^3
Triangle Z area = (17.5/2)cm^3 = 8.75cm^3
8.75cm^3 > 8.155cm^3 > 8.15cm^3
Therefore:
Triangle Z area > Triangle X area > Triangle Y area
I’m not a 100 percent but the answer is a because you have to subtract 3/2 - -13/2 which equals -16/2 and divide and u get -8
Alto earned $ 225 and Sheryl earned $ 250.
Given that Alto and Sheryl both worked hard over the summer, and together they earned a total of $ 475, and Sheryl earned $ 25 more than Alto, the following calculation must be performed to determine how much each one earned:
- S = A + 25
- A = A
- A + 25 + A = 475
- 2A = 475 - 25
- A = 450/2
- A = 225
- S = 225 + 25 = 250
Therefore, Alto earned $ 225 and Sheryl earned $ 250.

Answer: -24
Step-by-step explanation:
Let the unknown number be x , therefore ; The difference between the number and 6 implies x - 6
Also , twice their difference implies 2 ( x - 6 )
The sum of the number and 4 implies : x + 4
three times their sum implies : 3 ( x + 4 )
Combining all together , we have
2 ( x - 6 ) = 3 ( x + 4 )
Expanding , we have
2x - 12 = 3x + 12
collecting the like terms , we have
2x - 3x = 12 + 12
-x = 24
multiply through by -, we have
x = -24
Check :
2 ( x - 6 ) will give
2 ( -24 - 6 )
= 2 (-30)
= -60
3 ( x+4) will give
3 ( -24 + 4 )
= 3 ( -20)
= -60
Therefore:
2( x- 6 ) = 3 ( x + 4 )
