The answer is 7/5 th. You can add fractions without first having a common denominator so you would change the 8's by multiplying it by 5 to get 40 and you would multiply the 5 by 8 to get 40 as well. And the rule whatever you do to the bottom you have to do to the top so whatever you multiplied 8 by do the same for the numerator and whatever you multiplied 5 by you do the same for the numerator. So your new equation would be (75/40+16/40)+(-35/40). you would then add the numerator's across to get 56 and the denominator would stay the same so the answer is 56/40. But you have to now simplify 56/40 down to 14/10 and then once more to 7/5 which is the final answer.
<span> If all numbers are greater than zero and no repeated numbers exist these are the 5 possible combinations:
1 + 2 + 8
1 + 3 + 7
1 + 4 + 6
2 + 3 + 6
2 + 4 + 5.

Answer:
500
Step-by-step explanation:
each computer is 500 dollars
$25a + $15s =$305
a + s = 17
a = 17 - s
$25a +$15s =$305
$25(17-s) + $15s=$305
425-25s +15s = $305
425-10s=305
-10s=305-425
-10s= -120
-10s/-10 = -120/-10
s = 12
a+ 12 = 17
a = 5
Check
$25a + $15s =$305
$25(5) + $15(12) =$305
125 + 180 = 305
305 = 305
Answer:
The correct option is a)
: m ≤ 30,
: m > 30
Step-by-step explanation:
Consider the provided information.
A pizza shop advertises that they deliver in 30 minutes or less or it is free.
People who live in homes that are located on the opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza.
: Pizza shop makes and delivers the pizza ≤ 30 minutes.
: Pizza shop makes and delivers the pizza m > 30 minutes.
Hence, the correct option is a)
: m ≤ 30,
: m > 30
