Answer:
Equation: 5x + 10 = 30
Simplified Equation: 5x = 20
Number of problems assigned per person (at the start): 4
Total number of problems assigned per person: 6
Step-by-step explanation:
Hello!
We know that there were 5 students at the after-school tutoring and that the same number of problems were assigned to each person.
Let x = # of problems assigned to each student.
Since there were 5 students, x is multiplied by 5 so we can represent that as 5x
Next, 2 problems were assigned to each of the 5 students, so that can be represented as 5*2 or 10
If we add both values, they should equal to 30:
5x + 10 = 30
Simplified version: 5x = 20
Value of x : 4
The attendance at school one day was 720. This represented 96% of the total enrollment. What was the total enrollment of this school?
7,707 ÷ 24
what does this Equal and what is the remainder?
Answer:
321 R 3
Step-by-step explanation:
the quotient is 321 with a remainder of 3
you can check your work by doing 321 * 24 + 3 = 7,707
Answer:
321 r3
Step-by-step explanation:
(break up the 7707 to 77 and 07)
24x3= 72
72-77= 5 (apply the 07 to get 507)
24x21=504
507-504= 3 (remainder)

write an expression for the amount of sugar Farid needs to make 1/2 of a batch of muffins.
Answer:
[tex]\dfrac{3}{4} \ * \ \dfrac{1}{2}[/tex]
Explanation:
Full batch requires [tex]\sf\frac{3}{4}[/tex] cups of sugar.
she is making half the batch so we shall half it.
[tex]\sf\frac{3}{4}[/tex] ÷ 2 → [tex]\sf\frac{3}{8}[/tex] → 0.375note: we can write x ÷ 2, as [tex]* \ \sf\dfrac{x}{2}[/tex]
She is making half batch only, So she will require the half amount of sugar which means we need to multiply 1/2 and 3/4
[tex] \frac{1}{2} \div \frac{3}{4} [/tex]
[tex] \frac{1×3}{2×4} [/tex]
[tex] \frac{3}{8} [/tex]
She will require 0.375 cup of sugar for making 1/2 batch...~

A set of equations is given below:
Equation R: y = 5x + 10
Equation S: y = 5x + 5
Which of the following options is true about the solution to the given set of equations? (4 points)
Select one:
a.
One solution
b.
Two solutions
c.
Infinite solutions
d.
No solution
Answer:
There is no solution
Step-by-step explanation:
The slopes are the same and the y-intercepts are different.
Think of this as the slope as an amount you get per week and y-intercept as how much you start off with. You have a friend that starts off with 10 dollars and gains 5 dollars every week and you start off with 5 dollars and gains 5 dollars every week. Will you ever catch up to your friend if you and your friend don't spend any money? I don't think so. The solution to a set of equations is when both equations have the same y value with the same x value.

Perimeter formula for rectangle: 2L + 2B
Step-by-step explanation:
Length = 8.5 cm
Breadth = B
Perimeter = 24 cm.
2 (8.5) + 2B = 24
17 + 2B = 24
2B =24-17
2B = 7 cm
B = 7 / 2
B = 3.5 cm
Breadth = 3.5 cm
Length =8.5 cm
Perimeter =24 cm

For a given input value x, the function g outputs a value y to satisfy the following equation. -4x-6=-5y+2. write the formula for g(x) in terms of x. g(x)=
Answer:
Theory: g is the parent, y is the child, and x is the supporting number in the formula's syntax.
Step-by-step explanation:
-4(x a number) - 6 = -5(y a number) + 2.
basically g(x) is g times x equals y, which is the supporting factor in this equation.

What is the image of ( -9, 0) after a reflection over the X-axis?
Answer:
(-9,0) It would stay the same.

Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side KL. Round your answer to the nearest tenth if necessary.
Answer:
KL = 11.9 approximately
Step-by-step explanation:
It is stated that the two quadrilaterals are similar
if they are similar then their side lengths are proportional
So we can use that to find KL
JG/NK = GH/KL
(52.5)/17=37/KL cross multiply expressions
52.5*KL = 629 divide both sides by 52.5
KL = 11.9 approximately
Order 27.657, 27.658, 27.558, and 27.659 in decreasing order.
Thx-Kheri Moore

1. 27.659
2. 27.658
3. 27.657
4. 27.558
Step-by-step explanation:
Decreasing order is greatest number to the least.
I really hope this helps
27.659, 27.658, 27.657, 27.558
First, to compare each decimal you look at each place. You look at the tens and then ones, tenths, hundredth, and thousandth. They all start with 27, so you look at the tenth place.
27.5
27.6
27.6
27.6
5 is less than 6, so that would go last
Continue going on to the hundredth place with the rest of the numbers.
27.65
27.65
27.65
In the hundredth place, they all have the digit five, so you go on to the thousandth place.
27.657
27.658
27.659
7 is less than 8 or 9, so that goes second to last.
8 is less than 9, so that goes after 27.657 .
9 is the biggest, so that goes first

The table shows the relationship between the number of drops of food color added to different number of cups of cake frosting:
Cups of
Frosting Drops of
Food Color
2 6
3 9
4 12
Which point below shows an equivalent ratio in this situation?
I'd say that they are all equivalent because when you divided all of them it equals each other.
2:6 = 1/3
3:9 = 1/3
4:12 = 1/3

4 (x + 7) = 38
x=
Answer:
x = 2.5
Step-by-step explanation:
Hello!
Let's solve the equation together :)
Solve:
4(x + 7) = 38 => Over here, we want to multiply x and 7 by 4, or distribute 4 to both numbers inside the parenthesis.4(x) + 4(7) = 38 =>See how I split the multiplication apart? That's called the Distributive Property4x + 28 = 38 => Simplify. Now subtract 28 from both sides4x = 10 =>Now that we multiply x by 4, we divide both sides to isolate x x = 10/4 => Simplifyx = 2.5Your answer is x = 2.5
Check:
Plug in 2.5 into our equation
4(x + 7) = 384(2.5 +7) = 384(2.5) + 4(7) = 3810 + 28 = 3838 = 38Both sides match so our answer is correct.
