The parkers will pay A. $708.75
21 feet by 27 feet is 7 yards by 9 yards (3 feet per yard)
the area of the room is 7 yards * 9 yards = 63 square yards
if the carpet is $11.25 per square yard, multiply that number by the area
11.25 * 63 = 708.75
2(3x+7)+x=70
mutiply the bracket by 2
(2)(3x)(2)(7)+x= 70
6x+14+x= 70
6x+x+14= 70 ( combine like terms)
7x+14= 70
move 14 to the other side
sign changes from +14 to -14
7x+14-14=70-14
7x= 56
divide both sides by 7
7x/7= 56/7
x=8
Answer: x= 8
The train travels 70 miles per hour
Answer:
370,000 centimeters
Step-by-step explanation:
1. There are 1000 meters in a kilometer.
2. 3.7 kilometers x 1000 = 3,700 meters
3. There are 100 centimeters in a meter
4. 3,700 x 100 = 370,000 centimeters
It’s a ratio and for it to equal 2 x will equal 4
