A) Lets write our equations.
22x + 100 = 25x + 70
Now lets solve step-by-step.
Apply the inverse operation 22x + 100 = 25x + 70
-22x -22x
25x - 22x = 3x
3x + 70 = 100
-70 - 70 We subtract 70 from both sides because (inverse operation)
3x = 30
3x/3 = 30/3
x = 30/3
x= 10
B) We need to find which one is the most cheap.
Lets pick an integer to replace x.
22x + 100 = 25x + 70
Lets choose '2'
22(2) + 100 = 25(2) + 70
44 + 100
50 + 70
144
120
The first one : Country Carpets charges $144 , while at the same rate, City carpets charges 120.
So, obviously, City Carpets is cheaper than that other one, so he would most likely choose that one.
Answer:
D) 5,200
Step-by-step explanation:
The formula to find the area of a r rectangle: l x w, where l is the length and w is width.
Area of the backyard: 50 x 80
= 4,000 ft
Area of the house: 40 x 30
= 1,200 ft
Total = 4,000 + 1,200
= 5,200 ft²
9514 1404 393
Answer:
A, B
Step-by-step explanation:
Divide both sides by 6 to see what those values should be:
x < 4
Of course all negative numbers are less than 4, so choices A and B are correct. The given positive numbers are not less than 4, so the remaining choices are not correct.
