The number of days that Aubrey can drive to stay in her budget is 5 days.
<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

Answer:
5 units
Step-by-step explanation:
We can use the formula for finding the length or magnitude of line joining two points.
Length = √((x2-x1)² + (y2-y1)²)
The points joining the line are C (-1,4) and D (2,0)
Length = √((2+1)² + (0-4)²)
= √((3²) + (-4)²)
= √ (9+16)
= √25
= 5 units
Answer:
Zamir 75%
Caleb 72%
Rosa 76%
Work
<u>Zamir</u>
.75=75%
75*40=3000
3000/ 100= 30
<u>Zamir got 30 out of 40</u> questions right
<u>Caleb</u>
30-12=18
<u>Caleb got 18 out of 25</u> questions right now find percent
18*100=1800
1800/ 25= 72
Caleb got 72%
<u>Rosa</u>
18+1=19
<u>Rosa got 19 out of 25 </u>questions correct now find percent
19*100=1900
1900/ 25=76
Rosa got 76%
X=-2 and y=3.
The first step we take is to substitute the value for y from the second equation into the first equation:
4x+5(3x+9)=7
This is justified by substitution. The next step is:
4x+5*3x+5*9=7
4x+15x+45=7
This is justified by the distributive property. The next step is:
19x+45=7
This is justified by addition of like terms. The next step is:
19x+45-45=7-45
19x=-38
This is justified by the subtraction property of equality. The next step is:
19x/19 = -38/19
x=-2
This is justified by the division property of equality. The next step is:
y=3(-2)+9
y=-6+9
y=3
This is justified by substitution, multiplication and addition, in that order.
