Answer:
x = 6
y = -1
Step-by-step explanation:
-2x + 5y = -17 ------ equation 1
3x- 10y = 28 ------- equation 2
equation 1× 2
-4x + 10y = -34 ------- equation 3
equation 2 + equation 3
-x = -6
x = 6
x = 6 substitute for equation 1
-12 + 5y = -17
5y = -5
y = -1

There are 7 girls and 13 boys in a class at a Private
School. Of these students, 5 girls and 3 boys are in
the Running club. What percentage of the students
at this Private School are in the Running club?
Answer:
40%
Step-by-step explanation:
Number of girls = 7
Number of boys = 13
Total students = 7 girls + 13 boys
= 20 students
Running club
Number of girls = 5
Number of boys = 3
Total students in the running club = 5 girls + 3 boys
= 8 students
percentage of the students that are in the Running club = Total students in the running club / Total students
× 100
= 8/20 × 100
= 0.4 × 100
= 40%
Percentage of the students
at this Private School are in the Running club is 40%

Which graph represents the equation y = 2x + 1?
Answer:
B, the second one.
Step-by-step explanation:
Take the equation, y=2x+1. 1 is the y-intercept, so that automatically eliminates some potential answer choices. Your slope is 2/1, so you would use rise over run to find the correct answer choice.
Answer:
B the second one
Step-by-step explanation:
I got right trust me frfr
5y= 1/2x -10 find slope and y intercept.
Answer:
Slope = 1/10
Y intercept = -2
Step-by-step explanation:
5y = 1/2x - 10
Divide both sides by 5
5y/5 = 1/2x - 10 /5
You will get y = 1/0x - 2
The x part is the slope and the whole number on the far right is the y intercept.
So the slope is 1/10
The y intercept = -2
Which inequality does the graph represent?
A. y −x − 3
B. y > −x − 3
C. y ≤ −x − 3
D. y ≥ −x − 3
Answer:
y > −x − 3

Answer: 16312.5
Step-by-step explanation:
That took a lot of time. There you go.
Answer:
163125
Step-by-step explanation:
Divide the numbers then divide the exponents. Put them back together once done.
[tex]\frac{5.22}{3.2} = 1.63125[/tex]
[tex]\frac{10^{9}}{10^{4}} =10^{5}[/tex]
To get 163125, I moved the decimal point 5 places to the right since the exponent is 5.
[tex]1.63125*10^{5}=163125[/tex]

The sum of two consecutive even integers is 48 less than 3 times the largest integer. Find both integers algebraically.
Answer:
44 and 46Step-by-step explanation:
Let the integers be:
n and n + 2Then we have:
n + n + 2 = 3(n + 2) - 48Solving for n:
2n + 2 = 3n + 6 - 483n - 2n = 2 + 48 - 6n = 44So the numbers are 44 and 46
1) Find f(g(x)) and
9(f(c)).
Given: f(x) = 5x; g(x) = x - 3
f(g(x))
Step-by-step explanation:
= f(g(x)) = g(f(x))
= f(x - 3) = g(5x)
= 5(x- 3) : 5x - 3
: 5x - 15
Which expression represents the sum of 31 and 104,
divided by 3?
Answer:
The answer is 45Step-by-step explanation:
Well all you really need to do is add 31 and 104 which is 135 then divide it by 3 and well you got the answer 45
The expression (31 + 104) / 3 is equal to 45.
The expression that represents the sum of 31 and 104, divided by 3, can be written as (31 + 104) / 3.
To calculate the value, we start by evaluating the sum of 31 and 104, which gives us 135. So, the expression becomes 135 / 3.
Dividing 135 by 3 yields a result of 45.
Therefore, (31 + 104) / 3 is equal to 45.
The expression simplifies the process of finding the sum of the two numbers (31 and 104) by first adding them together and then dividing the sum by 3. This calculation provides a concise representation of the desired arithmetic operation and its solution.
