Ronald rents a car from Cheap Rent-a-Car for $25 plus $0.05 per mile. Dixon rents a car
from Great Cars for S40 plus $0.03 per mile. How many miles must they both drive for
their rental fees to be the same?
Answer:
750 miles
Step-by-step explanation:
Ronald
Rental fee = fixed cost + variable cost
= $25 + $0.05x
Where x = number of miles
Dixon
Rental fee = fixed cost + variable cost
= $40 + $0.03x
How many miles must they both drive for their rental fees to be the same?
Equate the two equations
$25 + $0.05x = $40 + $0.03x
Collect like terms
0.05x - 0.03x = 40 - 25
0.02x = 15
Divide both sides by 0.02
x = 15 / 0.02
= 750 miles
A restaurant manager states the number of customers that enter the
restaurant is equal to 3 times the number of people that buy a hotdog from
the hotdog cart plus 15.
The manager also states that the number of customers that enter their
restaurant is equal to 2 times the number of people that buy a hotdog from
the hotdog cart plus 60.
What number of people buying a hotdog from the hotdog cart across the
street makes the equation 3x +15 = 2x +60 true?
Answer:
Yes, that is true, and x=45.
Step-by-step explanation:
Yes, that's how you set up the equation I also listed the sets to solve it below:
3x+15=2x+60
-2x. -2x
--------------------
x+15=60
-15 -15
------------------
x=45
You can also plug it in to check your work.
3(45)+15=2(45)+60
135+15=90+60
150=150

“An elephant charged 13.3 meters in 15 seconds.
At this rate, how far would the elephant move if it
could charge for 1 minute?”
Answer:
53.2 metersStep-by-step explanation:
If an elephant charged 13.3 meters in 15 seconds, to calculate the distance charged by the elephant in one minute, the following steps will be arried out.
15 seconds = 13.3 meters
1minute (60 seconds) = x
cross multiply
15 * x = 13.3 * 60
15x = 798
Divide both sides by 15
15x/15 = 798/15
x = 53.2metres
Hence the elephant will charge 53.2 meters for 1 minute

Answer:
B
Step-by-step explanation:
So we want to find the value of x.
Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:
[tex]JK=JI+IK[/tex]
We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:
[tex]2x-1=(2)+(x+3)[/tex]
On the right, add:
[tex]2x-1=x+5[/tex]
Add 1 to both sides:
[tex]2x=x+6[/tex]
Subtract x from both sides. The right cancels:
[tex]x=6[/tex]
And the value of x is 6.
Our answer is B.

The value of f(10) for function f(x) = 2x² + 9x is 290.
What is an algebraic expression?An algebraic expression is consists of variables, numbers with various mathematical operations,
The given function is,
f(x) = 2x² + 9x (1)
To find the value of f(10),
Substitute x = 10,
f(10) = 2(10)² + 9(10)
f(10) = 2 x 100 + 90
f(10) = 200 + 90
f(10) = 290
