Luke bought 2 used games at the game store if each used game cost $7.85 and he paid with a twenty dollar bill how much change should get back
Answer:
$4.30
Step-by-step explanation:
First, find the cost of both games by multiplying the price by 2:
7.85(2)
= 15.7
Then, to find his change, subtract this from 20:
20 - 15.7
= 4.3
So, Luke should get $4.30 back in change.

At India’s arcade 2/3 of the games are racing games. Among the racing games, 1/2 are motorcycle racing games. What fraction of the games at India’s arcade are motorcycle racing games
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Motorcycle racing games = [tex]\frac{1}{2}[/tex] × [tex]\frac{2}{3}[/tex] (Directly multiply)
= [tex]\frac{2}{6}[/tex] (Simplify)
= [tex]\frac{1}{3}[/tex] (Tada!)
bryan runs 2 miles every 40 minutes. At this rate, how many minutes did Bryan run if he ran 8 miles?
2 ÷ 40 = 20
so
1 mile = 20 minutes
20 minutes × 8 miles = 160 minutes
160 minutes into hours and minutes = 2 hours and 40 minutes
Answer:
160 minutes or 2 hours and 40 minutes

Answer:
4x-4+3
Step-by-step explanation:
Answer:
-4+4x=3
Step-by-step explanation:
So the first step is to derive an equation from the model.
There are 4 positive x and 4 negative 1 which equal 3 positive 1 which should look like:
4x-4=3
which could be rewritten as:
-4+4x=3

Describe how (2 ^ 3)(2 ^ - 4) can be simplified . Multiply the bases and add the exponents. Then find the reciprocal and change the sign of the exponent . The same base and add the exponents . Then multiply by - 1 . The base and multiply the exponents . Then multiply by -1 Add the exponents and keep the same base Then find the reciprocal and change the sign of the exponent .
Answer:
Add the exponents and keep the same base Then find the reciprocal and change the sign of the exponent .
Step-by-step explanation:
Given the expression (2^3)(2^- 4), we will apply the law of indices below to solve the equation;
[tex]a^m \times a^n = a^{m+n}\\a^{-m} =\frac{1}{a^m}[/tex]
Applying this on the given expression;
[tex](2 ^ 3)(2 ^{-4})[/tex]
Step 1: Add the exponents and keep the same base as shown;
[tex]= (2 ^ 3)(2 ^{-4})\\\\= 2^{3+(-4)}\\\\ = 2^{3-4}\\\\= 2^{-1}[/tex]
Step 2: Find the reciprocal and change the sign of the exponent
[tex]= 2^{-1} \\= \frac{1}{2^1}\\= \frac{1}{2}[/tex]

Step-by-step explanation:
Consider the function h(x)=1/2x-3 with a restricted domain of {-2,0,2,10}. What is the range of the function?
Answer: {-4,-3,-2,2} or c on the test nav assessment Question 7.
Step-by-step explanation:
It asks for the range. Range is your output. Which is your y. Plug in your domain (which is your x or input).
Your domain is {-2,0,2,10}
h(-2)=1/2(-2)-3=-4
h(0)=1/2(-0)-3=-3
h(2)=1/2(2)-3=-2
h(10)=1/2(10)-3=2
Actually B. If it’s asking for the restricted domain. Because a restricted domain, is a domain with a denominator. And this doesn’t have a denominator. So it would be all real numbers.
The range of function is {-4, -3, -2, 2} if the function h(x)=1/2x-3 with a restricted domain of {-2,0,2,10}.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We are assuming the function is:
[tex]\rm h(x) =\dfrac{1}{2}x-3[/tex]
The domain of the function: {-2,0,2,10}
Find the value of the function at points -2, 0, 2, and 10:
h(-2) = 1/2(-2)-3 = -4
h(0) = 1/2(-0)-3 = -3
h(2) = 1/2(2)-3 = -2
h(10) = 1/2(10)-3 = 2
So the range of function will be {-4, -3, -2, 2}
Thus, the range of function is {-4, -3, -2, 2} if the function h(x)=1/2x-3 with a restricted domain of {-2,0,2,10}.

find the amount of x. 2x+4=3x-10
Answer:
x=14
Step-by-step explanation:
You want to get x by itself on one side so you start by canceling the smaller x: 2x. You do this by subtracting 2x from both sides. You should have 4=x-10. After this, you want to cancel the -10 to get x by itself. To do this, you have to add 10 on both sides. You should have x=14. Lmk if this helps!
Answer: x=14
Step-by-step explanation:
2x+-3x=-4-10
-1x=14
X=14

Solve for x.
A) 10
C) 11
B) - 7
D) 12
Answer:
i think it is A) 10
Step-by-step explanation:
Answer:
D. 12
Step-by-step explanation:
The middle line is two times shorter so:
x - 2 = 2(2x - 19)
simplify
x - 2 = 4x - 38
subtract 4x from both sides
-3x - 2 = -38
add 2 to both sides
-3x = -36
divide both sides by -3
x = 12
Solve for X and Y PLEASE HURRY
A copy machine can print 480 copies every 4 minutes. How many copies can it print in 10 minutes? :)
Answer: 1200
Step-by-step explanation:
since every 4 minutes it can make 480 copies
Peisonally I would divide to see hou uch it could make in ONE minute
so 480/4 = 120
so it makes 120 copies per minute
now simply multiply by 10
120 x 10 = 1200 copies.
hope this helps! :)

Write the equation of a line whose graph has the same slope as
3x – 9y = 9 and the same y-intercept as 8x – 2y = 6.
Answer:
y= 1/3x -3
Step-by-step explanation:
For the y-int for 8x-2y=6 is (0, -3).
For the slope of 3x-9y=9 is 1/3.

Based on this scatterplot, if Carley runs in a 4-kilometer race and she maintains the same pace, how many minutes will it take her to run 4 kilometers?
The question is incomplete, the complete question is;
Based on the graph, if Carley runs in a 4- kilometer race and she maintains the same pace, how many minutes will it take her to run 4 kilometers?
A 50 minutes
B 45 minutes
C 35 minutes
D 20 minutes
Answer:
C 35 minutes
Step-by-step explanation:
If we look at the scatter plot closely, we can trace the distance of 4 Km on the vertical axis down to its matching point on the horizontal axis.
If this is done correctly, you will discover that the point on the time axis corresponding to the 4 Km distance on the vertical (distance) axis is 35 minutes (the point lies mid-way between 30 minutes and 40 minutes points on the horizontal axis).
Therefore, it will take Carey 35 minutes to run 4 Kilometres according to the scatter plot.

Priya has completed 9 exam questions. This is 60% of the questions on the exam.
Answer:
Your answer is 15, 100% of the exam is 15 questions.
Step-by-step explanation:
60% x ? = 9
We need to do 9 divided by 60%
Which is actually 9 divided by 60/100.
Which is equal to; (100 x 9) divided by 6.
Which is then 900 divided by 60 which equals 15.
