Answer:
x = ³/₅
Step-by-step explanation:
1⅔/x = 2⁷/₉ Convert the right-hand side to improper fraction
1⅔/x = ²⁵/₉ Multiply each side by x
1⅔ = ²⁵/₉x Convert the left-hand side to improper fraction
⁵/₃ = ²⁵/₉x Multiply each side by 9
15 = 25x Divide each side by 25
x = ³/₅
<em>Check: </em>
1⅔/⅗ = 2⁷/₉
⁵/₃ × ⁵/₃ = ²⁵/₉
²⁵/₉ = ²⁵/₉
Answer:
subtract 11 from both sides I think is what you're asking
Step-by-step explanation:
Answer: Barbarino's rentals has a better deal.
She has to drive 887.5 miles to spend the same amount at either company.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em>Mr.kotters rentals (A)
</em>
- <em>$99 PER WEEK
</em>
- <em>$0.11per mile over 100 miles
</em>
<em>Barbarino's rentals (B)
</em>
- <em>$75 per week
</em>
- <em>$0.15 per mile over 150 miles
</em>
For "A"
Cost = 0.11 (432-100) + 99 = $135.52
For "B"
Cost= 0.15 (432-150) +75 = $117.3
Barbarino's rentals has a better deal, since $117.3(B) < $135.52 (A)
To find how many miles would Glenna drive before she would be spending the same amount at either company:
A =B
0.11 (M-100) + 99 =0.15 (M-150) +75 = $117.3
Solving for M (miles)
0.11 M -11+99 = 0.15 M -22.5+75
-11 +99 +22.5 -75 =0.15M -0.11 M
35.5 = 0.04M
35.5/0.04 = M
887.5 =M
She has to drive 887.5 miles to spend the same amount at either company.
