Answer:
C) 21 girls : 9 boys
Step-by-step explanation:
You just have to compare the ratio you're given to the answers and see if the ratios from the answers match up to the ratio you were given. The reason C is the answer is because if you divide by 3 in the ration, it is the same as the ratio you were given, 7:3

What is the equation of the line in slope -intercept form? *
A. y= x +8
B. y= x - 8
C. y = 8x +8
D. y = 8x - 8
Answer:
d
Step-by-step explanation:
The equation of the line in slope -intercept form is y=x-8, Option b is correct.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
From the graph let us take two points of line joining which are (8, 0) and (0, -8).
m=-8-0/0-8=1
So slope of line is 1.
Now let us find find the y intercept
0=1(8)+b
0-8=b
b=-8
Slope intercept form of line is y=x-8
Hence, the equation of the line in slope -intercept form is y=x-8, Option b is correct.

X + (-4) = -2
What does X repesents??? Please help
Answer:
x=2
Step-by-step explanation:
x+(-4) is the same as x-4
First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.
x-4=-2
+4 +4
x= -2+4 or you can see this as 4-2 which is 2
x=2
erica earn money by tutoring and babysitting. She always tutors for 5 hours each week and the amount she babysits changes from week to week. let x be the hours that arica babysitters. Write an expression to show the total numbers of hours erica works each week.
Numbers That you have to use to solve this problem: +,-, . , =, ( , ), x, 5, 8, 13.
The expression to show the total number of hours erica works each week is 5 + x.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.
Given that Arica earns money by tutoring and she did by 5 hours each week and she also babysits for x hours each week.
Hence, 5 + x will be the correct expression to show the total number of hours erica works each week.
So erica earns money of a total of that 5 + x of the week the value of x is anything it could be 1 ,2 anything.

The value of y when solving the equation 2(y−6)+3=4y−7 is:
Answer:
-1
Step-by-step explanation:
2(y−6)+3=4y−7
2y−12+3=4y−7
2y-12+12+3=4y-7+12
2y+3=4y+5
2y+3-3=4y+5-3
2y-4y=4y-4y+2
-2y=2
-2y/-2=2/-2
y=-1
The value of y in the given algebraic expression when simplified is; y = -1
How to Solve Algebraic Problems?We are given the algebraic expression;
2(y − 6) + 3 = 4y − 7
Expand the bracket to get;
2y − 12 + 3 = 4y − 7
Use addition property of equality to add 12 to both sides to get;
2y - 12 + 12 + 3 = 4y - 7 + 12
2y + 3 = 4y + 5
Subtract 3 from both sides to get;
2y + 3 - 3 = 4y + 5 - 3
2y = 4y + 2
4y - 2y = -2
2y = -2
y = -2/2
y = -1

cups of water with
1/3
cup of orange juice concentrate.
—————————
How much water would she use for one cup of concentrate? (use a decimal)
—————————
How much water would she use for 10 cups of concentrate? (use a decimal)
Answer:
1. 1 cup of concentrate would use 7.5 cups of water.
2. 10 cups of concentrate would use 75 cups of water.
Step-by-step explanation:
Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
[tex]8 \times 2 = 3 \times x.[/tex]
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.
