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
Answer:
x is the price of the meal
(1+0.0825 + 0.18) is the total percentage on top of the price he pays with sales tax and tip.
Step-by-step explanation:
The factor x is the price of the meal. The factor (1 + 0.0825 + 0.18) is the 100% of the price, the sales tax on that price and the tip on the total. 1 + 0.0825 + 0.18 = 1.2625 is the total percentage he pays on the price. He pays 26.25% in addition of the price of the meal to cover tax and tip.
Answer:
D
Step-by-step explanation:
Log[6] * 4x2 + -1log[6] * x = 2
Reorder the terms for easier multiplication:
6 * 4glo * x2 + -1log[6] * x = 2
Multiply 6 * 4
24glo * x2 + -1log[6] * x = 2
Multiply glo * x2
24glox2 + -1log[6] * x = 2
Reorder the terms for easier multiplication:
24glox2 + -1 * 6glo * x = 2
Multiply -1 * 6
24glox2 + -6glo * x = 2
Multiply glo * x
24glox2 + -6glox = 2
Reorder the terms:
-6glox + 24glox2 = 2
Solving
-6glox + 24glox2 = 2
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Reorder the terms:
-2 + -6glox + 24glox2 = 2 + -2
Combine like terms: 2 + -2 = 0
-2 + -6glox + 24glox2 = 0
Factor out the Greatest Common Factor (GCF), '2'.
2(-1 + -3glox + 12glox2) = 0
Ignore the factor 2.
Subproblem 1
Set the factor '(-1 + -3glox + 12glox2)' equal to zero and attempt to solve:
Simplifying
-1 + -3glox + 12glox2 = 0
Solving
-1 + -3glox + 12glox2 = 0
Move all terms containing g to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + -3glox + 1 + 12glox2 = 0 + 1
Reorder the terms:
-1 + 1 + -3glox + 12glox2 = 0 + 1
Combine like terms: -1 + 1 = 0
0 + -3glox + 12glox2 = 0 + 1
-3glox + 12glox2 = 0 + 1
Combine like terms: 0 + 1 = 1
-3glox + 12glox2 = 1
weekly = 15 week = 10
