Step-by-step explanation:

for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls
so amount of boys=84-48=36
there are 36 boys
Answer:
6:00 or 6 o'clock
Step-by-step explanation:
1) Add 2 to the hours. So, 3+2=5
2) Add 15 minutes to 45 minutes. So, 15+45=60
3) 60 minutes is an hour, so therefore add one more hour. 5+1=6
4) There are 6 hours and 0 minutes.
So, the time that Renita finished her homework was 6:00.

Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
What value of b will cause the system to have an infinite number of solutions?
y = 6x – b
–3x + 1/2y = –3
we have
----->equation A
-----> equation B
we know that
If the system has infinite number of solutions then, the equation A must be equal to the equation B
so
isolate variable y in the equation B

Multiply by
both sides

-------> new equation B
To find out the value of b, equate equation A and equation B
