Answer: 6
Step-by-step explanation:
From the question, we are informed that a factory uses 1/8 of a barrel of raisins in each batch of granola bars and that the factory used 3/4 of a barrel of raisins yesterday.
To calculate the number of batches of granola bars that the factory made yesterday, we divide 3/4 by 1/8. This will be:
= 3/4 ÷ 1/8
= 3/4 × 8/1
= 24/4
= 6
The company made 6 batches of granola bars
(74 + 78 + 70 + x) / 4 = 80
Divide each number by 4.
18.5 + 19.5 + 17.5 + x = 80
Add the numbers you know so far.
18.5 + 19.5 + 17.5 = 55.5
You need 24.5.
Now, since we divided all the others by 4, we have to multiply 24.5 by 4 to see what the exam score would be.
24.5 * 4 = 98.
To get an average of 80%, the student would need to get a 98 on their fourth exam.
Answer:
here you go
Step-by-step explanation:
no of times he failed = -3
points he losed = -3 x 4 = -12
no of times he need to hit the target to get 48 points = 6x
<u>equation</u>
<u>-12 + 6x = 48</u>
<u>6x = 60 </u>
<u>x = 10</u>
no of points he will gain = 10 x 6 = 60
