Basically you need to multiply the percent by the number.
(6, 2 )
substitute x = 5 into the equation and solve for y
6y + 8 = 20 ( subtract 8 from both sides )
6y = 12 ( divide both sides by 6 )
y = 
= 2
the ordered pair is (5, 2 )
Answer:
The inverse operation of squaring a number is finding the square root of a number. The square root cancels out the square. For example, 3² = 9. To cancel out the square, we have to take the square root. So, √9 = 3. Hope this helped.Step-by-step explanation:
Answer: True
Step-by-step explanation:
We can simplify each of the expressions on either side to see if they are equal.
Left side: -5+7=7-5= 2
Right side: 7+-5=7-5= 2
Yes, they are equal.
Answer:
Total cost of the trip = 243 + 72x
Step-by-step explanation:
Cost of airfare = $243
Amount spent per day = $72
Which expression can he use to help him find the cost of the trip?
Let
x = number of days spent in Alaska
Total cost of the trip = Cost of airfare + (Amount spent per day * number of days spent in Alaska)
= 243 + (72 * x)
= 243 + 72x
Total cost of the trip = 243 + 72x
If he spent 4 days on the trip
Total cost of the trip = 243 + 72x
= 243 + 72(4)
= 243 + 288
= $531
