Answer:
a. 80.25
b. 104
Step-by-step explanation:
For (a), you add all the numbers together and divide by 4 because there are 4 test scores.
87 + 92 + 63 + 79 ÷ 5 = 80.25
For (b), we need to set up an equation. It is going to be a similar concept.
87 + 92 + 63 + 79 + x ÷ 5 = 85
x = 104
Hope this helps!
p = 4x + 3y
x = 5
y = -2
Plug in values of x and y.
p = 4(5) + 3(-2)
p = 20 - 6
p = 14
<h3>The value of p is 14.</h3>

Answer: 34
Step-by-step explanation: the ratio is 3:2 we know that there are 51 orange sweets but we don’t know how many are yellow so the current ratio is 51:x we need to find x so if we divide 3 by 51 the answer is 17 so we need to multiply 17 by 2 which is 34 so x is equaled to 34 the final ratio is 51:34
