The answer is true. Read the statement correctly
Answer:the company bought 12 computers and 4 printers.
Step-by-step explanation:
Let x represent the number of computers that the company bought.
Let y represent the number of printers that the company bought.
The company buys a total of 16 machines. It means that
x + y = 16
Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that
550x + 390y = 8160 - - - - - - - - - - 1
Substituting x = 16 - y into equation 1, it becomes
550(16 - y) + 390y = 8160
8800 - 550y + 390y = 8160
- 550y + 390y = 8160 - 8800
- 160y = - 640
y = - 640/ - 160
y = 4
Substituting y = 4 into x = 16 - y, it becomes
x = 16 - 4
x = 12
Answer:
They are similar....... Trust me
Answer:
Simply divide both sides by 10:
2915/10 = 10x/10 → 291.5 = x
<u>X = 291.5</u>
Answer:
If the time is less than 5 hours cost less to hire Hank’s Movers
Step-by-step explanation:
Let
y -----> charge to move household goods across town.
x ----> number of hours
we know that
<em>Acme Movers</em>
y=40x+175 ------> equation A
<em>Hank’s Movers</em>
y=75x ------> equation B
Equate equation A and equation B
75x=40x+175
solve for x
75x-40x=175
35x=175
x=5 hours
For x=5 hours the charge is the same in both company
therefore
For x < 5 hours cost less to hire Hank’s Movers
