Answer:
The equation is: [tex]\frac{x}{2} = 7.3[/tex]
Step-by-step explanation:
Caroline was thinking of a number.
We are going to call this number x.
Caroline halves the number and gets 7.3.
To find half of a number, we multiply by 1/2. So
[tex]\frac{1}{2} \times x = 7.3[/tex]
[tex]\frac{x}{2} = 7.3[/tex]

Answer:
(5,-1)
x=5
y= -1
Step-by-step explanation:
To solve this we're going to solve for one variable in either equation
so we have
x+y=4
We can subtract y and 4 from both sides to get
x-4= -y
Then divide by -1 so that y will be a positive number
-x+4=y
We can plug this in for y in the other equation
2x -2(-x+4)=12
Distribute the -2 and get
2x+2x-8=12
Combine like terms and add 8 to get
4x=20
divide and get x=5
Plug in x=5 into the first equation to get
5+y=4
subtract 5 to get y= -1
Our answer is (5,-1) or x=5 y= -1
I checked this on desmos and the math is correct
Answer:
The solution to the system of equations will be:
x = 5, y = -1
Step-by-step explanation:
Given the system of equations
x + y = 4
2x - 2y = 12
Isolate x for x + y = 4: x = 4 - y
substitute x = 4 - y in the equation 2x - 2y = 12
2(4-y) - 2y = 12
8 - 2y - 2y = 12
8 - 4y = 12
4y = 8 - 12
4y = -4
divide both sides by 4
4y/4 = -4/4
y = -1
substitute y = -1 in x + y = 4
x + y = 4
x + (-1) = 4
x - 1 = 4
x = 5
so
(x, y) = (5, -1)
Therefore, the solution to the system of equations will be:
x = 5, y = -1

The ratio of boys to girls in Ms. Reedus's classroom is 2 to 3. There are 18 girls in the classroom. What is the total number of students in Ms. Reedus's class?
Answer: The final answer is 30.
Step-by-step explanation: The question says the ratio is 2 boys : 3 girls. There are 18 girls. Well, how did you get from 3 to 18? You multiply by 6. But whatever you do to the denominator you have to do with the numerator. So, multiply 2 and 6. That gives you 12 boys and 18 girls. Adding 12 and 18 gives you 30. Therefore, there are 30 students in the whole class.

Write an equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
(-8, 6)
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is:
y = -4 + 38
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
We have given that,
An equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1
(-8, 6)
What is the slope-intercept form?
y=mx+b
Where m is the slope
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b

Which graph represents an exponential function?
Answer:
A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.
This diagram represents 3 batches of light yellow paint. Draw a diagram that represents 1 batch of the same shade of light yellow paint. white paint (cups) yellow paint (cups) Show your work here.
Answer: we need 3 cups of white paint and 5 of yellow paint if we want to make 1 batch.
Step-by-step explanation:
I suppose that each one of these squares represents one cup of the given color.
(the white squares represent the cups of white paint and the yellow squares represent the number of cups of yellow paint)
We know that for 3 batches of the paint, we need:
9 cups of white paint.
15 cups of yellow paint.
Now, if we only want to do one batch, then we should use one-third of these numbers of cups. (Because with that we make 3 batches, and one-third of 3 batches is one batch)
Originally, we use 9 cups of white paint, then for one batch we need one-third of 9 cups, this is:
9/3 = 3
Then we should use 3 cups of white paint.
And for the yellow paint, we originally use 15 cups, one-third of 15 is:
15/3 = 5
Then we should use 5 cups of yellow paint.
We can conclude that we need 3 cups of white paint and 5 cups of yellow paint if we want to make 1 batch.
This would be represented with 3 white squares and 5 yellow squares.

Nori had 2 1/12 bags of apples. He used 1 5/12 bags of apples to make pies How many bags of apples does Nori has left
Answer:
3 1/2
Step-by-step explanation:
Answer is 8/12.
Mixed number Fraction:
A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
(Here),
Nori had [tex]2\frac{1}{12}[/tex] bags of apples.
Given, he used [tex]1\frac{5}{12}[/tex] bags of apples.
Nori left = [tex]2\frac{1}{12}[/tex] - [tex]1\frac{5}{12}[/tex]

Write the exponent for the expression.
1/9 x 1/9 x 1/9=?
HELP FAST plz
Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is [tex]\frac{1}{9} ^3[/tex] or 1/9 to the 3rd power.
Down is a formula I made!
Main number: 1/9
Repeating how many times: 3

What is the solution to the equation 1/4x+2=-5/8x-5?
O X=-8
O X=-7
O X=7
O X=8
Answer:
The solution to the equation [tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex] is [tex]\mathbf{x=-8}[/tex]
Option A is correct option.
Step-by-step explanation:
What is the solution to the equation [tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex]
Solving the equation
[tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex]
Subtracting 2 on both sides
[tex]\frac{1}{4}x+2-2=\frac{-5}{8}x-5-2\\\frac{1}{4}x=\frac{-5}{8}x-7[/tex]
Adding 5/8x on both sides
[tex]\frac{1}{4}x+\frac{5}{8}x=\frac{-5}{8}x-7+\frac{5}{8}x\\\frac{2x+5x}{8}=-7 \\\frac{7x}{8}=-7[/tex]
Multiply both sides by 8/7
[tex]\frac{7x}{8}\times \frac{8}{7}=-7 \times \frac{8}{7}\\x=-8[/tex]
So, we get x = -8
The solution to the equation [tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex] is [tex]\mathbf{x=-8}[/tex]
Option A is correct option.
