Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15
The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows.
Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges.
Company B:8x5=40+15=$55 for 8 windows and service charges.
Company B would charge less for 8 windows.
Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service charges
My work for Company B: 6x5=30+15=$45 for 6 windows + service charges
$48-$45=$3
Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.
Answer:
(x + 5) /2
Step-by-step explanation:
"a number" (this will represent as "x")
"increased" another way to say add or "+"
then divided by 2
If you wrote it out like this "x+5/2"it would be wrong because of PEMDAS making you want to divide first instead of after.
Answer:
65.94 cm²
Step-by-step explanation:
12.5/2 = 6.25 = radius of large circle
8.5/2 = 4.25 = radius of small circle
A= πr²
A of large circle = 3.14(6.25²) = 122.66
A of small circle = 3.14 (4.25²) = 56.72
122.66 - 56.72 = 65.94 cm²
