Answer:
[tex] - 4x - 2y = - 12 \\ 4x + 8y = - 24 \\ \\ 6y = - 36 \\ y = \frac{ - 36}{6} = - 6 \\ \\ - 4x - 2( - 6) = - 12 \\ - 4x + 12 = - 12 \\ - 4x = - 12 - 12 \\ - 4x = - 24 \\ x = \frac{ - 24}{ - 4} = 6 [/tex]

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
3/4 ÷ 6
= (3/4)/6
= 3/(4 x 6)
= 3/24
= 1/8
Thus,
1/8 is the value.

What is the answer ? (Evaluate if x=6, y=8, and z=3)
5x - (y + 2z)
The solution of the expression is 5x - (y + 2z) is 16.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the expression is 5x - (y + 2z). the values are x=6, y=8, and z=3. The expression will be solved as:-
E = 5x - (y + 2z)
E = ( 5 x 6 ) - ( 8 + 2 x 3 )
E = 30 - ( 8 + 6 )
E = 30 - 14
E = 16
Hence, the value of the expression is 16.

Answer:2, 1, (in place of x) and y2
Step-by-step explanation: Divide your base numbers, which are 18 and 9, so you get 2. Then because you're dividing with exponents you are just subtracting them. So x 2-2 (Imagine these as exponents) so you'd get x0. Next you'd do the same with y so you'd end up with y2. Because your exponent is 0 on x it equals one.

Question:
Triangles PQR and RST are similar right triangles. Which proportion can be used to show that the slope of PR is equal to the slope of RT?
Answer:
[tex]\frac{3 - 7}{-4 - (-7)} = \frac{-5 - 3}{2 - (-4)}[/tex]
Step-by-step explanation:
See attachment for complete question
From the attachment, we have that:
[tex]P = (-7,7)[/tex]
[tex]Q = (-7,3)[/tex]
[tex]R = (-4,3)[/tex]
[tex]S = (-4,5)[/tex]
[tex]T = (2,-5)[/tex]
First, we need to calculate the slope (m) of PQR
Here, we consider P and R
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex]P(x_1,y_1) = (-7,7)[/tex]
[tex]R(x_2,y_2) = (-4,3)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{3 - 7}{-4 - (-7)}[/tex] --------- (1)
Next, we calculate the slope (m) of RST
Here, we consider R and T
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex]R(x_1,y_1) = (-4,3)[/tex]
[tex]T (x_2,y_2)= (2,-5)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{-5 - 3}{2 - (-4)}[/tex] ---------- (2)
Next, we equate (1) and (2)
[tex]\frac{3 - 7}{-4 - (-7)} = \frac{-5 - 3}{2 - (-4)}[/tex]
From the list of given options (see attachment), option A answers the question

A. 5
B. 8
C. 12
D. 20
Answer:
[tex]\boxed{x=5}[/tex]
Step-by-step explanation:
[tex]\frac{1}{2} (4x-5)+\frac{5}{2} =10[/tex]
→ Multiply everything by 2
[tex]1(4x-5)+5=20[/tex]
→ Expand out the bracket
[tex]4x-5+5=20[/tex]
→ Simplify
[tex]4x=20[/tex]
→ Divide both sides by 4 to isolate x
[tex]x=5[/tex]

Out of a group of 60 students, 24 are boys. What percent of the students are boys? (5 points for work and 5 points for answer)
Answer:
40%
Step-by-step explanation:
The first step is to write 24 as a fraction of 60, which is simply
24/60
In order to find the simplest form of the fraction 24/60 we cancel out the greatest common divisor of 24 and 60, which is 12 :
24/60=2/5
Now we just need to convert this fraction to a percentage :
2/5 = 40

WHAT THE HELL IS THIS!?!?!
Step-by-step explanation:
Answer:
B (12x=180)
Step-by-step explanation:
When you combine like terms for the numbers with x's, you get 12x and the -10 and 10 cross each other out. This leaves you with 12x=180 (since a triangle always adds up to 180).
what numbers multipy to -20 and add to 6
Answer:Perhaps you made a typo because there is no solution to this problem.
Step-by-step explanation:
We know one of the numbers is negative and one is positive since when multiplied the output is negative. And the negative number will be the smaller of the two since the sun is positive. So the factors of -20 are:
-1•20 -1+20=19
-2•10 -2+10=8
-4•5 -4+5=1
None of those equal 6 so i apologise but it seems this equation has no answer.
Three numbers are in ratio 2:5:7.
The middle number is 75. What are the other two numbers?
Answer:
First number - 30
Second number - 105
Step-by-step explanation:
2/5 of 75 would be 30, so it is the answer.
7/5 of 75 would be 105, so it is the answer.
This is how you would solve this problem.

You own a flower shop. You regularly order roses and carnations and want to check the pricing. You cannot find the pricing information but have these invoices.
10 boxes of carnations 5 boxes of roses
12 boxes of carnations 10 boxes of roses
total 370$ total 225$
Write and solve a system of equations to find the price of each box of roses and carnations. Be sure to define your variables.
Answer: One box of carnations costs $10 and one box of roses cost $25.
Step-by-step explanation: You will have three variables in this; c for carnations, r for roses, and t for total. Your equation will look like this: 10c+25r=t; The ten and twenty-five are the amount it costs for one box of carnations and roses.
