Please help‼️‼️‼️‼️‼️ Melanie plans to repaint some classroom bookcases.She has 1 7/8
gallons of paint. All of the bookcases are the same size and each requires 3/16 gallon of paint. How many bookcases will she be able to paint
Answer:
The custodian will be able to repaint 7 bookcases with the amount of paint.
Step-by-step explanation:
The custodian has 5 1/4 gallons of paint, to find the number of bookcases the custodian will be able to repaint with this amount of paint if each bookcase requires 3/4 gallons, then we will simply divide 5 1/4 by 3/4 to give us the number.
But first we need to change 5 1/4 to improper fraction,
thus; 5 1/4 =
5 1/4 ÷3/4 = ÷
(We will want to change the division sign to multiplication, to do that, we will have to take the inverse of 3/4 which is 4/3 hence;
= ×
4 will cancel out 4 hence;
=
= 7
Therefore the custodian will be able to repaint 7 bookcases with the amount of paint.
What operation should be done first to solve 5x + 3 = 28?
Multiply by 5
Add 3
Subtract 3
Divide by 5
Answer:
Subtract 3
Step-by-step explanation:
The first operation that should be done first in the expression 5x + 3 = 28 is subtracting 3 from both sides.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, 5x + 3 = 28.
The first operation that should be done first is subtracting 3 to both the side of the equation to separate the variable x and the constant term.
∴ 5x + 3 - 3 = 28 - 3.
5x = 25.
x = 5.

Step-by-step explanation:
36 is 0.9% of what number
(not urgent
Answer: 4000
Step-by-step explanation:
If for example 5 is 1% of what number, you would multiply that by 100/1 and multiply that by 5.
For 36 is 0.9% of what number, you would multiply the 36 by 100/0.9 and multiply that by 36.
100/0.9 is 111.11 and 111.11 x 36 is 4000, so 4000 would be your answer.

The sum of two numbers is 65 and the difference of those two numbers is -18
Answer:
41.5
23.5
Step-by-step explanation:
Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:
x + y = 65
The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:
x - y = -18
Now solve equation B for x to get the revised equation B:
x = -18 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 65
-18+y+y=65
-18 + 2y = 65
2y = 83
y = 41.5
Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:
x + y = 65
x + 41.5= 65
X = 23.5
DIfference : 23.5 - 41.5 = 18
Sum: 41.5 +23.5 = 65
Hence, The two number are 23.5 and 41.5

What value for a would make the equation true? Type in only the numerical answer or value.
Answer:
a = 3
Step-by-step explanation:
Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.
In either case, you get the following equation:
8(2a-1) = 4(a+7)
Open the parenthesis
16a - 8 = 4a + 28
Subtract 4a from both sides
12a - 8 = 28
Add 8 to both sides
12a = 36
Divide both sides by 12
a = 3

The Alvarezes are trying to decide which of two catering companies to hire for their anniversary party. Marvelous Meals charges $700 plus $35 per person. Posh Parties charges $425 plus $50 per person. Both companies are known for their good food and excellent service, so the Alvarezes want to choose the caterer that will cost less. Write the equation to represent Marvelous Meals. *
Given :
Marvelous Meals charges $700 plus $35 per person. Posh Parties charges $425 plus $50 per person.
To Find :
Which company will cost less.
Solution :
Let, after x people Marvelous Meals charge less than Posh Parties :
So, 700 + 35x < 425 + 50x
275 < 15x
x > 18.33 i.e x > 18
Therefore, after 18 people Marvelous Meals charge less than Posh Parties.
Hence, this is the required solution.

Answer with step-by-step explanation:
m = 0.8
Firstly, we have to see how many M's we are dividing. On the image, it shows 2m + 2m + m + m = 6m. Then, we divide 6 by 4.8, since is would give us the correct value of m. 4.8 ÷ 6 = 0.8.

If using the method of completing the square to solve the quadratic equation
x2 -9x + 2 = 0, which number would have to be added to "complete the square"?
Answer:
Add the square of half of the coefficient of [tex]x[/tex] to both sides
[tex]\left(-\dfrac92\right)^2=\dfrac{81}{4}[/tex]
Completing the square:
Rewrite [tex]x^2-9x+2=0[/tex] in the form [tex]y=(x-b)^2 +c[/tex]
Add the square of half of the coefficient of [tex]x[/tex] to both sides:
[tex]\implies x^2-9x+2+\left(-\dfrac92\right)^2=\left(-\dfrac92\right)^2[/tex]
[tex]\implies x^2-9x+2+\dfrac{81}{4}=\dfrac{81}{4}[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 +2=\dfrac{81}{4}[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 +2-\dfrac{81}{4}=0[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 -\dfrac{73}{4}=0[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 -\dfrac{73}{4}=0[/tex]
