Hi can someone plss help me turn this equation into standard form (I don't really know how)
Answer:
2x - 4y = 8
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
4y = 2x - 8 ( subtract 2x from both sides )
- 2x + 4y = - 8 ( multiply through by - 1 )
2x - 4y = 8 ← in standard form
Erin needs to make at least a 75 on her semester exam to maintain a B in the class. Which number line correctly represents this situation?
A.
B.
C.
D.
Answer:
C
Step-by-step explanation:
"At least 75" means Erin needs a score that is 75 or more. Her score should be equal to or greater than 75.
The number line that shows this is C because the point at 75 is filled in (showing that 75 is included), and the ray (arrow) extends to the right indicating numbers larger than 75.
Simplify the expression and combine like terms.
Answer:
5x + 16
Step-by-step explanation:
the first thing you do in this equation is to distribute the 2 into x + 6
you get
2x + 12 + 3x + 4 = ?
then you must put the 2x and the 3x together
5x + 12 + 4
and you can then add the 12 and 4
5x + 16
Kadeem has a case for art supplies shaped like a rectangular prism. The volume of the case is 100 cubic inches, and it’s height is 5 inches
Witch table has values that could be the length and width of the case?
The product of the length and width must be equals to 20. Therefore, it could be 4 and 5(or reverse) or 10 and 2(or reverse).
Volume of a rectangular prism:v = lwhwhere
l =length
w = width
h = height
Therefore,
v = 100 inches³
h = 5 inches
Therefore, the length and the width can be as follows;
100 = 5lwdivide both sides by 5
lw = 100 / 5
lw = 20
Therefore, the product of the length and width must be equals to 20. Therefore, it could be 4 and 5(reverse) or 10 and 2(reverse).

Ten less than 5 times the value of a number is equal to 10 times the quantity of
12 more than one-fourth of the number. Ifa is the number, what is the value of a?
Write and solve an equation to find a. Show your work.
10 less than 5 times the value of a number -> 5a - 10
10 times the quantity of 12 more than one-fourth of a number -> 10(12+1/4a)
We have :
5a - 10 = 10(12 + 1/4a)
5a - 10 - [10(12 + 1/4a)] = 0
5a - 10 - (120 + 5/2a) = 0
5a -10 - 120 - 5/2a = 0
Group : (5a-5/2a) - (10 + 120) = 0
5/2a - 130 = 0
5/2a = 130 -> a = 130 : 5/2 = 52
Recheck : 5 x 52 - 10 = 250
10 x (12 + 1/4 x 52) = 10 x (12 + 13) = 10 x 25 = 250

Heidi wants to make some biscuits using this recipe.
Makes 12 biscuits
125 g butter
200g flour
50 g sugar
Heidi thinks that she has,
500 g butter
700 g flour
Assuming that the these weight are correct work out the greatest number of biscuits Heidi can make
250 g sugar
Assuming that these weights are correct,
(a) work out the greatest number of biscuits Heidi can make.
You must show all your working.
The most cookies Heidy can make is 36 cookies.
How to calculate how many cookies can Heidy make?To know how many cookies Heidy can make, you have to take into account the following information:
12 cookies need the following ingredients:
125g butter200g flour50g sugarIn the case in which Heidy has more ingredients, we must carry out the following operations:
Divide the quantities, in the reference quantity we have:
500g of butter ÷ 125g of butter = 4700g flour ÷ 200g flour = 3.5250g of sugar ÷ 50g of sugar = 5According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.
So the number of cookies Heidy can make are:
12 × 3.5 = 42

Heidi can make a maximum of 36 biscuits with the available ingredients.
Given that the Available ingredients are:
Butter: 500 g
Flour: 700 g
Sugar: 250 g
Required ingredients per batch:
Butter: 125 g
Flour: 200 g
Sugar: 50 g
Let's calculate the maximum number of batches Heidi can make for each ingredient:
Batches based on Butter:
500 g butter / 125 g butter = 4 batches
Batches based on Flour:
700 g flour / 200 g flour = 3.5 batches
=3 batches
Batches based on Sugar:
250 g sugar / 50 g sugar = 5 batches
Therefore, the greatest number of biscuits Heidi can make is the number of batches multiplied by the number of biscuits per batch:
Number of biscuits per batch = 12 biscuits
Number of batches = 3 batches
Greatest number of biscuits Heidi can make = Number of biscuits per batch × Number of batches
Greatest number of biscuits Heidi can make = 12 biscuits/batch × 3 batches = 36 biscuits
So, Heidi can make a maximum of 36 biscuits with the available ingredients.

What is the approximate volume of a baseball with a radius of 1.5 inches?
Answer:
V ≈ 14.14 cubic inches.
Step-by-step explanation:
To find the volume of a baseball with a radius of 1.5 inches, you can use the sphere volume formula ( [tex]\frac{4}{3}\pi r^{3}[/tex] ) to solve:
[tex]\frac{4}{3}\((3.14159) (1.5)^{3}[/tex] = 14.137155
14.137155 rounds to 14.14
Therefore, 14.14 cubic inches is approximately the answer.

Charlie and Rashan collect miniature cars. They have the same number of cars in their collections. Charlie sold 5/8 of his collection. Rashan sold 4/10 of his collection. Who sold more of their collection? Use the drop-down menus to solve and answer the problem. Compare each fraction to the benchmark fraction 1/2.
Answer:
5/8 is more than 1/2 4/10 is less than 1/2 so 5/8 is more than 4/10
So that means that Charlie sold more of his collection than Rashan

Find the percent increase from 275 to 561.
Answer:
104%
Step-by-step explanation:
(275 × p) / 100 = 286
((275 × p) / 100) × 100 = 286 × 100
275p = 28600
275p / 275 = 28600 / 275
p = 104
Percent Increase = 104
Answer:
==> 104%
Step-by-step explanation:
Working Out
The problem we are solving is:
Work out the percentage increase between 275 and 561.
Difference is 561 - 275 = 286.
Divide the difference between the original number:
286 / 275 = 1.04.
Multiply by 100 to change to a percentage:
1.04 x 100 = 104%.
This number is positive so we have a percentage increase of 104%.

Jayden needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 3.75 hours and charged him $60 for parts. The total was $528.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answer:
$125 and hour - (528.75 - 60) / 3.75
Step-by-step explanation:
Since the total includes the $60 for the parts, we have to subtract 60 from 528.75. Once we've found the difference (468.75), we can divide by the amount of hours (3.75). That leaves us with the answer, $125.
