Multiply 1/4 and 8, and the answer is 2, which is option C.
Answer:
16 students got an A
Step-by-step explanation:
Set up an equation to compare the ratio to the scores:
Cross multiply:
80 = 5x
Divide each side by 5:
x = 16
Now, check if
16/8 = 2
40/8 = 5
The ratios are the same! Therefore, 16 students got an A!

So adding on to the comment, we have;
(a) + (a + 1) = -195
Which then becomes:
2a + 1 =-195
Subtracting 1 on both sides
2a = -196
Dividing both sides by 2:
a= -98.
Therefore, the two consecutive integers are -98 and -97.
Just to make sure, test it out!
Answer:
D) 74
Step-by-step explanation:
1c = 6p
1c = 1.5f
1f = 296
6/1.5 = 4
296/4 = 74
55% of 1800 = 0.55(1800) = 990...so there are 990 girls in the school
30% of 990 = 0.30(990) = 297...so there are 297 girls who take the bus
