Answer:
1. 4 nights
2. $154
Step-by-step explanation:
1. The airfare is a fixed cost, and the cost of staying at the hotel for n nights is 98 * n. So, we add this up: 478 + 93n. This cost can be <em>no more than</em> 850 because that's Jenna's budget limit. So, we have:
478 + 93n ≤ 850
Subtract 478 from both sides:
93n ≤ 372
Divide by 93:
n ≤ 4
The maximum number of nights is 4 nights.
2. Abigail currently has $45 and she needs m more dollars in order to achieve her goal of <em>at least</em> $199. Seeing "at least", we know that we need to use the ≥ sign:
45 + m ≥ 199
Subtract 45 from both sides:
m ≥ 154
Abigail still needs at least $154.
Hope this helps!
Isolate x in 2nd equation...
-x - 2y = -10 ....add 2y to both sides
-x = 2y - 10 ...multiply by -1 to make x positive
x = -2y + 10 <== u would sub in -2y + 10 in for x in the 1st equation

Answer:
The answer is 16x + 7
Step-by-step explanation:
First you want to add all of the like terms.
(8x + 10 + 12x + 7) - (4x+10)
20x + 17 - (4x + 10)
Now you want to subtract all of the like terms
16x + 7
