Jamal's score is 80
<u>Explanation:</u>
Given:
Number of questions = 100
Let w be the number of wrong answers
Let r be the number of right answers
According to question,
r = 4w
r + w = 100
Solving both the equations we get:
4w + w = 100
5w = 100
w = 20
If w = 20 then r = 4 X 20 = 80
Therefore, Jamal's score is 80
Answer:
B
Step-by-step explanation:
We know that it costs 37 cents to mail a letter that weighs 1 oz or less. This would mean that for x ≤ 1, P(x) should equal 37. Already, we can eliminate A and D.
We also know that it costs an additional 26 cents for at most another ounce added to the original 1 ounce. This means that for 1 < x ≤ 2, P(x) = 26 + 37 = 63. This is shown by B.
Thus, the answer is B.

Answer:
Rudy is 13 years old. Her father is 45 years old.
Step-by-step explanation:
It's very simple actually!
<u>All you need to do is subtract 32:</u>
58 - 32 = 26
<u>Then divide:</u>
<u />
26 ÷ 2 = 13
13 is Rudy's age. Let's find her father's age!
<u>We then add 32 back to 13:</u>
32 + 13 = 45
And there you have it!
Hope this helped! :)
