Answer:
I am not sure about the actual answer but hopefuly you figure this out
Step-by-step explanation:
To get the number of boys and girls you do 3+5 to get 8. 120 divided by 8 is 15. so every digit in the ratio is 15 students. 15x3 is 45 and 15x5 is 75. there are 45 girls and 75 boys. 16/25 of the boys go climbing. There are 75 boys so you do 16x3 because 25x3 is 75 so 16x3 is 48. 48 boys go climbing. 120-48 is 72. and 27 boys go sailing.
1. x-2(2x-3.5)=-14
x-4x+7=-14
-3x=-21
x=7
2. y=2(7)-3.5
y=14-3.5
y=10.5
hope this helps!
Answer: hello! I'm here to help.
Let's work the problem using just the thousands and leave the zeros off. We'll add them back at the end.
Let M be the salary of the Master's degree, and B be the salary of the Bachelor's degree.
M + B = 120
M + 39 = 2B
M = 2B - 39
2B - 39 + B = 120
3B - 39 = 120
3B = 159
B = 53
M = 120 - B = 120 - 53 = 67

Step-by-step explanation:
3r + (9 + 2r + 1)
this can be simplified :
3r + (9 + 2r + 1) = 3r + 2r + 9 + 1 = 5r + 10
