Answer:
x = 70°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an external angle of the triangle, thus
x + 50 = 120 ( subtract 50 from both sides )
x = 70
Answer:
B) $10.00
Step-by-step explanation:

Answer:
-a - 4
Step-by-step explanation:
3(a-2)+4(3-a)-10
3a - 6 + 12 - 4a - 10
-a - 4
Answer:
12/45

<h3>Inequality signs and their meanings</h3>
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
<h3>Equation that represents the question</h3>
Total amount that can be spent ≤ (cost to rent a car per day x number of days) + (cost per mile x total miles driven)
$130 ≤ ($22.15 x dd) + ($0.07 x 275)
<h3>Determination of the number of days that Aubrey can drive</h3>
130 ≤ ($22.15dd) + ($0.07 x 275)
130 ≤ $22.15dd + 19.25
130 - 19.25 ≤ $22.15dd
110.75 ≤ 22.15d
d ≤ 110.75 / 22.15
d ≤ 5
