Answer:
The answer is £157.5.
Step-by-step explanation:
Another way of <u>decreasing by a percentage is to increase by that percentages compliment.</u>
Since 100-12.5 = 87.5%. We can <u>increase 180 by 87.5% to get the same result.</u>
0.875*180 = 157.5
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
