Answer:
see below
Step-by-step explanation:
Let y = the total cleaning cost
Let x = the number of roots cleaned.
Therefore, if the cost is $22 per room, y = 22x
200 = 22x
Divide both sides by 22: 9 
= x
Therefore, 9 rooms can be cleaned for $200
New equation: y = 22x + 40
200 = 22x + 40
Subtract 40 from each side: 160 = 22x
Divide both sides by 22: 7 
= x
Therefore, 7 rooms can be cleaned for $200 if the carpet cleaners receive a $40 tip
Follow the order of operations!!
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
that is in order. follow these and you should figure it out yourself :)
The surface area will be 4 times the original size. Here is why: You are doubling each dimension, and area is a 2 dimensional measurement. Because of this whatever you are doing to the length of the side will happen 2 times. In this case it would be x2 x2 which equals 4. You can provide evident by using a cube. The surface area of a cube with side lengths of 1 would be 1 x 6=6 square inches. If you double the side length, it would be 4 x 6= 24 square inches.
4)
A=1/2 bh
A = 1/2(6)(3)
A = 9 in^2
5)
A=1/2 bh
A=1/2(7)(10)
A = 35 m^2
6)
A=1/2 bh
A=1/2(5)(8)
A=20 ft^2
7)
A=1/2 (b1+b2)h
A=1/2 (5+10)8
A=60 in^2
8)
A=1/2 (b1+b2)h
A=1/2 (13+19) 10
A=160 mm^2
9)
A=1/2 (b1+b2)h
A=1/2 (3+6) 2
A = 9 ft^2
