evaluate each expression for the given value of x.
Answer:
x=10
Step-by-step explanation:
2x-12 = 18
+12 +12
2x=20
20/2 = 10
Answer:
24
Step-by-step explanation:
Original equation:
2x - 12 = ?
We know x = 18
So, just plug the value into the equation
2(18) - 12
Multiply 2 by 18
36
Subtract 12 from 36

15/4-13/3
45/12-52/12
-7/12
Step-by-step explanation:
Answer:
You are not dumb
Step-by-step explanation:
15/4 - 4 1/3 make the 4 1/3 a improper fraction
15/4 - 13/3 find common denominator of 12
45/12-52/12 since 4 goes into 12 3 times, times the top by 3 to get 45. The second one-3 goes into 12 4 times, so times the top by 4 to get 52.
45/12-52/12= 45-52= -7 put the -7 over the 12
-7/12 that is your answer

You can divide and multiply the ratio by 2 to get an equivalent ratio.
The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
As per the given ratio, 10:12.
Divide numerator and denominator by 2
(10/2):(12/2) = 5:6.
Multiply the numerator and denominator by 2
(10×2);(12×2) = 20:24
Hence "The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24".

Answer:
Choice D
Step-by-step explanation:
When you find the unit price it will be easier to eliminate the other choices and to find the unit price I found the easiest numbers to work with, so if we do $5 divided by 2 lbs it'll give us $2.5 and that's our unit price. Then for the graphs we are left with choices C and D. So all we have to do is see which one has the line passing through point (2,5) which stands for 2 oranges and $5.
A set of equations is given below:
Equation H: y = -x + 2
Equation J: y = 3x - 4
Which of the following steps can be used to find the solution to the settlement of equations? (4 points)
a: -x = 3x - 4
b: -x +2=3x
c: -x + 2 = 3x -4
d: -x + 1= 3x + 2
Answer:
Option C is the correct option.
Step-by-step explanation:
A set of equations is given below:
Equation H: y = -x + 2
Equation J: y = 3x - 4
We need to determine the step to solve the equations.
We can place value of y from Equation H into Equation J
i.e
-x+2=3x-4
So, Option C is the correct option.

Seth's father is thinking of buying his son a summer movie pass for $30 dollars. With the pass, matiness cost $4 each.
Without the pass each movie is normally $8. If Seth plans to go to 30 movies this summer how much money would he
save?
Answer:
Seth saved $90.
Step-by-step explanation:
1.Find out how much would be spent without buying the movie pass.
Multiply the amount of money that one would spend for each movie, by the number of movies one saw.
8 * 30 = 240
2.Find out the amount that was actually spent
Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.
(4 * 30) + 30
= 120 + 30
= 150
3. Find the difference between the two values.
Subtract the amount that one was supposed to spend by the amount one did spend.
240 - 150
= 90
A video game store adds a 25% markup on each of the games that it sells. In addition to the manufacturer's cost, the store also pays a $1.50 shipping charge on each game.
Answer:

What is the greatest number of 19 cent stickers that can be purchased with a $20 bill, assuming there is no sales tax?
Answer:
105
Step-by-step explanation:
First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.

It takes 2 workers 10 minutes to plant 3 trees. If all workers plant trees at the same constant rate, how many minutes will it take 4 workers to plant 24 trees?
40
if it takes two workers 10 minutes to plant 3 trees,then it will take 4 workers 5 minutes to plant 3 trees.3÷24=8,then 5×8=40
If it takes 2 workers 10 minutes to plant 3 trees then it will take 4 workers 40 minutes to plant 24 trees.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The rate at which each worker plants trees.
If two workers can plant 3 trees in 10 minutes, then one worker can plant 3/2 trees in 10 minutes
One worker can plant 1.5 trees in 10 minutes, or 0.15 trees per minute.
Now, we can use this rate to find how long it will take 4 workers to plant 24 trees.
Since each worker plants at a rate of 0.15 trees per minute
Four workers will plant at a combined rate of 0.15 x 4 = 0.6 trees per minute.
To plant 24 trees at a rate of 0.6 trees per minute, we can use the formula:
time = (amount of work) / (rate of work)
Plugging in the values, we get:
time = 24 / 0.6 = 40
Therefore, it will take 4 workers 40 minutes to plant 24 trees.

Answer:
8x^2+38x+45 so B
Step-by-step explanation:
i got it right on the test
The required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.
Given that,
Dan is tiling his rectangular, concrete porch with square, porcelain tiles. The length of the porch is represented by the function l(x)=4x+9, where x is the side length, in feet, of each tile. The width of the porch is represented by the function w(x)=2x+5.
The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.
Here,
Length of the porch = 4x + 9
Width of the porch = 2x + 5
area of the porch A(x) = (4x + 9) (2x + 5 )
= 8x² + 20x + 18x + 45
= 8x ² + 38x + 45
Thus, the required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.
