The system of equations has no solution:
True or False?
y = (2/3)x - 5
4x - 6y = 30
You are renting a car that charges a $30 fee plus 40 cents a mile. The rate of change is $30.
True or False?
Hi there!
»»————- ★ ————-««
I believe your answer is:
False.
0.40 is the rate of change.
»»————- ★ ————-««
Here’s why:
As mentioned in the scenario, the car company charges a $30 fee which is flat. The '30' is the base for the total cost. The car company also charges 40 cents for every mile driven. This means that the company would charge a 40 cents for a mile driven. 40 cents would be the rate of change, not $30.⸻⸻⸻⸻
Side Note:
An equation that represents the situation could be:
[tex]C = 0.40m + 30[/tex]
'C' is the total cost for renting the car.
'm' is the number of miles the car is driven.
⸻⸻⸻⸻

Jimmy's truck consumed 2 gallons of gasoline while travelling a distance of 76 km. He has 1.5 gallons left in the tank. How much farther can his truck go?
_______ km
I GIVE BRAINLIEST TO THE FIRST CORRECT ANSWER!!
Answer:
[tex]57\:\mathrm{km}[/tex]
Step-by-step explanation:
Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.
Let [tex]x[/tex] represent how much farther his truck can go, in kilometers:
[tex]\frac{2}{76}=\frac{1.5}{x}[/tex]
Cross-multiplying, we get:
[tex]2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}[/tex]
Answer:
Step-by-step explanation:
2 ÷ 76 = 1.5 ÷ d
2d = 76 × 1.5
d = 57 km

Answer:
1. 523 cm^3
2. 1.6 ft
Step-by-step explanation:
1. Formula for volume of a sphere is (4/3)(pi)(r^3)
r = 5
(4/3)(3.14)(5^3) ≈ 523
2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)
(1/3)(3.14)(1^2)(2) ≈ 2.0933
Plug this into the formula for volume of a sphere and find r.
2.093 = (4/3)(3.14)(r^3)
r ≈ 0.7937
Multiply by 2 to get the diameter, which is the height of the spherical barrier.
r * 2 ≈ 1.6

13/16 ÷ N = 2 1/6
What is n?
A:4/9
B: 3/8
C. 4/7
D.5/8
EXPLAIN
Answer:
N = 3/8 (Answer B)
Step-by-step explanation:
Here we need to isolate the variable N. Rewriting 2 1/6 as the equivalent 13/6, we get:
13/16 ÷ N = 2 1/6 = 13/6.
Then 13/16 ÷ N = 13/6, or
(13/16) 13
---------- = ------
N 6
Dividing both sides by 13, we get:
(1/16) 1
---------- = ------
N 6
Cross-multipying results in 6/16 = N.
Reducing this, we obtain the solution, N = 3/8 (Answer B)
Find the dfference between (8a + 2b - 4) and (3b - 5)
Answer:
8a-b+1
Step-by-step explanation:
Difference means subtract
(8a + 2b - 4) - (3b - 5)
Distribute the minus sign
(8a + 2b - 4) - 3b + 5
Combine like terms
8a + 2b-3b - 4 + 5
8a-b+1

Wes mixed different juices to make fruit punch. He filled one-half of the punch bowl with orange juice. Then he filled half of the remaining space with grape juice. Finally, he filled the rest of the punch bowl with 300 mL of cherry juice.
how many liters of fruit punch did Wes make?
_____liters
Answer:
Orange = 500
Grape = 250
Remaining = 300
1050 is the result.
Step-by-step explanation:
It says half of the space that remains, it is supposed to be 500, half of 500 is 250, which is the amount of grape juice, added together they give 750 and then it says the remainder with 300 of cherry, 750 + 300 = 1050.
