5 pounds- $17.50
1 pound- $17.50 divide by 5 pounds then multiple 1 pound=$3.50
10 pounds- $35
15 pounds- $52.50
20 pounds-$70
25 pounds- $87.50
30 pounds-$105
The answer is D, 30cm.
If you do 6+6+9+9 (to find the perimeter) you get your answer.
The answer is no solution.
Explanation:
Because of pemdas, first, solve the parentheses. It becomes 4.2x + 3, as multiplying by 0.5 caused the same effect as if you were to divide by 2. Now if you look at the problem, it is just 4.2x - 3 = 4.2x + 3. Even though the symbols are different, they are still equal to eachother.
A $80
The installments payments would be 940 in the end so you’d be paying 80 more dollars
