20 high x 18 long = 360 square feet
3 windows x (4 high x 3 long) = 3 windows x 12 square feet = 36 square feet
360 - 36 (because we obviously don't paint windows) = 324
324 square feet to paint on one wall
Answer:
x = 12
Step-by-step explanation:
Step 1: Define
f(x) = 2x - 7
f(x) = 17
Step 2: Substitute
17 = 2x - 7
Step 3: Solve for <em>x</em>
<u>Add 7 on both sides:</u> 24 = 2x
<u>Divide both sides by 2:</u> 12 = x
Step 4: Check
f(12) = 2(12) - 7
f(12) = 24 - 7
f(12) = 17

Step-by-step explanation:
2+5x+53=180
55+5x=180
5x=125
x=25

Answer:
Step-by-step explanation:
Let the number of Noodle Soups = x
Let the chips bring in 0.75 * (123 - x)
Together, the total amount will be 131.25
1.50*x + (123 - x) * 0.75 = 131.25 Remove the brackets on the left
1.50x + 123*0.75 - 0.75*x = 131.25 Combine the left
0.75x + 92.25 = 131.25 Subtract 92.5 from both sides
0.75x = 131.25 - 92.25 Combine the right
0.75x = 39 divide by 0.75
x = 39/0.75
x = 52
Answer
So the school sold 52 Noodle Soups
and 123 - 52 = 71 Hot fries.
