The expression 9p − 8q for p = 4 and q = −8 is equal to 100
<h3><u>Solution:</u></h3>
Given that we have to evaluate expression for the given values of the variables
Expression is:
⇒ 9p − 8q
Given that p = 4 and q = -8
<em><u>Let us substitute the given values of p = 4 and q = -8 in given expression and evaluate it</u></em>
⇒ 9p − 8q = 9(4) - 8(-8)
⇒ 9p - 8q = 9(4) + 8(8)
Upon multiplying the terms we get,
⇒ 9p - 8q = 36 + 64 = 100
Thus the expression is equal to 100
Answer:
Step-by-step explanation:
R=3 S=5 then it's 3x5 which is 15
3x2=6
Next do 15+6=21
Then do 21x3.14=65.94
(2,3) is your answer for the equation
Answer:
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
Step-by-step explanation:
350 = 12(x + 20)
Multiply out brackets: 350 = 12x + 240
Subtract 240 from both sides: 110 = 12x
Divide both sides by 12: 9 1/6 = x
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
