Answer:
x = 200
Step-by-step explanation:
Multiply by 4:
x + 120 + 2x = 720
3x = 600 . . . . . . collect terms, subtract 120
x = 200 . . . . . . . divide by 3
_____
<em>Check</em>
(200/4 +30) +(200/2) = 180
(50 +30) + 100 = 180
80 + 100 = 180 . . . . . true
_____ _____
<em>Alternate solution</em>
If you like, you can simply work with the equation given.
(3/4)x + 30 = 180 . . . . collect terms
(3/4)x = 150 . . . . . . . . . subtract 30
x = 200 . . . . . . . . . . . . multiply by 4/3
Answer:
X = 8.3 (shortened)
<u>Steps for answer!</u>
1. Subtract 2.5x from both sides.
1.5=4x-11-2.5x
2. Simplify 4x-11-2.5 to 1.5x-11
1.5=1.5x-11
3. Add 11 to both sides.
1.5+11=1.5x
4. Simplify 1.5+11 to 12.5.
12.5=1.5x
5. Divide both sides by 1.5.
12.5/1.5=x
6. Simplify 12.5/1.5 to 8.3333338.333333.
8.333333=x
7. Switch sides.
x=8.333333

Hey, I would say b or c! I’m not sure but lmk sorry if I’m wrong!
From the equation that was gotten, the value of the pecan pies and the cheesecake will be $9 each.
Based on the information given, the equations to solve the question will be:
9p + 8s = 153 ..... i
2p + 6s = 72 ..... ii
Multiply equation i by 2
Multiply equation ii by 9.
18p + 16s = 306
18p + 54s = 648
Subtract the equations
38s = 342
s = 9
Since 2p + 6s = 72
2p + 6(9) = 72
2p + 54 = 72
2p = 72 - 54.
2p = 18
p = 18/2 = 9
They're both $9 each
