25. You need to divide 3240 by 6, and 1100 by 2. Are those equal? That's what it's asking. It would not be equal, because 3,240 miles would be 540 miles per hour and 1100 would be 550 per hour. Very close, however.
26. If 15 scoops makes 5 gallons, then divide 15/5. That's 3 scoops per gallon. It's asking how many gallons can be made with 6 scoops. That would be 2 gallons.
27. All it's asking is 38 times 5, which would be 190.
28. Since 5 gallons goes into 15 gallons three times, you would divide $22.20 by 3. That would be $7.40 each 5 gallons.

Cynthia besch wants to buy a rug for a room that is 18ft wide and 35ft long she wants to leave a uniform strip of floor around r

Eduardwww [97]

Answer:

rug long = 34 ft

rug wide = 17 ft

Step-by-step explanation:

given data

wide = 18 ft

long = 35 ft

area of carpet = 528 ft

solution

we get here area of floor that is

and we consider length of carpet = 35 - 2x

and width = 18 - 2x

(35 - 2x) × (18 - 2x) = 528 ...................1

solve it we get

x = 25.5 and x = 1

we choose 1 ft. as the width of the strip

so rug long = 35 - 1 = 34 ft

and rug wide = 18 - 1 = 17 ft
