Add 0.5 to each side so you have fabric for the seams and your new numbers are 3 ft and 4 ft
find the area by multiplying 3*4 and get 12 ft
1 yard = 3 feet
12/3= 4 yards
You would need 4 square yards of fabric
Answer:
x = 21/8
Step-by-step explanation:
Step 1: Write equation
x - 11 = 3 - 7(x - 1)
Step 2: Solve for <em>x</em>
<u>Distribute -7:</u> x - 11 = 3 - 7x + 7
<u>Combine like terms:</u> x - 11 = 10 - 7x
<u>Add 7x on both sides:</u> 8x - 11 = 10
<u>Add 11 on both sides:</u> 8x = 21
<u>Divide both sides by 8:</u> x = 21/8
Answer:
x= −1/2, x=52/5
Step-by-step explanation:
2(x+7)=13
(2)(x)+(2)(7)=13(Distribute)
2x+14−14=13−14
2x=−1
2x/<u><em>2</em></u>=−1/<u>2</u>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5(x−7)=17
(5)(x)+(5)(−7)=17(Distribute)
5x+−35=17
5x−35=17
5x−35+35=17+35
5x=52
5x/<u><em>5</em></u>=52/<u>5</u>
3/8 = 0.375 hrs per wax
60 x 0.375 = 22.5 hrs for 60 cars
