Answer: First of all, add up the expressions with the same variables and the numbers.
7a-8-12a+4
=7a-12a-8+4
=-5a-4
or
=-(5a+4)
Both of them can be counted ans equivalent expression since all three of them works the same. Only the expression(way of writing) seems different.
Answer:
_ 5a - 4
Step-by-step explanation:
Combine Like Terms:
=7a + − 8 + −12a + 4
=( 7a + −12a ) + (− 8 + 4 )
=− 5a - 4 Answer!

Valentino needs 4 1/2 pounds of chicken for a recipe. He already has
2 3/4 pounds of chicken. How many more pounds of chicken does Valentino need?
Answer:
Valentino needs 1 [tex]\frac{3}{4}[/tex] more pounds of chicken for the recipe.
Step-by-step explanation:
You just need to know how to subtract fractions.
Valentino needs 4 and 1/2 pounds of chicken for a recipe, and he already has 2 and 3/4. We want to know how many more pounds of chicken we need, so you subtract.
4 1/2 - 2 3/4 = 4 2/4 - 2 3/4
= 1 3/4
Valentino needs 1 and 3/4 pounds of chicken still.

Which two expressions are equivalent? *
Answer:
6x+9x and 3(2x + 3x)
Step-by-step explanation:
Answer:
The Bottom Right option would be correct, 6x + 9x and 3 (2x + 3x)
Step-by-step explanation:
If put 3 (2x + 3x) in standard form, it would result in;
3 * 2x = 6x
3 * 3x = 9x
Therefore
3 (2x + 3x) = 6x + 9x

Answer:
n=10
Step-by-step explanation:
[tex] - 4(2 + 8) = ( - 4 \times n) \\ \frac{ - 4(10)}{ - 4} = \frac{ - 4n}{ - 4} \\ 10 = n[/tex]
Answer:
−4(2+8)=−4n
Step 1: Simplify both sides of the equation.
−40=−4n
Step 2: Flip the equation.
−4n=−40
Step 3: Divide both sides by -4.
[tex]\frac{-4n}{4} = \frac{-40}{-4}[/tex]

Collin needs to fix his broken air conditioner unit. He decides to call some mechanics to see what it might cost to get the unit repaired. Let’s x represent the number of hours and let y represent the total cost.
Company A: y = 25x + 20
company B: y = 20 + 45
it will take ____________ hours for the cost to be the same for both companies
5 hours if there was supposed to be an x after 20 on the second equation
It will take 5 hours for the cost to be the same for both companies.
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
Collin needs to repair his malfunctioning air conditioner.
He makes the decision to phone a few technicians to find out how much it would cost to fix the device.
Let x stand for the number of hours and y for the overall expense.
Company A: y = 25x + 20
company B: y = 20x + 45
To find the number of hours it will take for the cost to be the same for both companies, we need to solve the equation:
25x + 20 = 20x + 45
Simplifying the equation, we get:
5x = 25
x = 5
Therefore, x = 5

The perimeter of a square is 100 feet. What is the length of one of its sides? Explain your work.
Answer:
25
Step-by-step explanation:
to find the perimeter you add up all the sides and since it's a square and squares have all four equal sides
you just divide 100/4=25
4 sides of a square. Each side of a square is equal. You said the perimeter is 100. So if we put it in an equation, lets say S = Side. 4s=100. Now we just divide. s=25
Each side is 25

The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = [tex] \tt{ \frac{1}{2} h(a + b)}[/tex] where a and b are the opposite parallel sides and h be the height of a trapezium.[tex] \large{ \tt{❃ \: SOLUTION}} : [/tex]
In the first picture , we're provided - Length ( l ) = [tex] \frac{7}{4} [/tex] cm , breadth ( b ) = [tex] \frac{3}{2} [/tex] cm and height ( h ) = [tex] \frac{1}{2} [/tex] cm. Now, plug these known values and them find out the volume of given rectangular prism.[tex] \large{ \tt{❁ \: VOLUME \: OF \: RECTANGULAR \: PRISM \: ( \: V \: ) = l \times b \times h}}[/tex]
[tex] \large{ {⟶ \: \frac{7}{4} \times \frac{3}{2} \times \frac{1}{2} }}[/tex]
To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term if possible.[tex] \large{ ⟶ \frac{7 \times 3 \times 1}{4 \times 2 \times 2} }[/tex]
[tex] \large{⟶ \frac{21}{16} \tt{ {cm}^{3} }}[/tex]
Hence , the volume is [tex] \boxed{ \frac{21}{16} }[/tex] cubic centimetres.--------------------------------
In the second attachment , we're provided - 6ft and 7 ft are the opposite parallel sides and 3 ft is the height of the given trapezium.[tex] \large{ \tt{✺ \: AREA \: OF \: A \: TRAPEZIUM = \frac{1}{2} h(a + b)}}[/tex]

Answer:
1)
V = l * w * h
7/4 * 3/2 * 1/2 = 21/16 cm^3
2)
A = a+b ÷ 2 * h
6 + 4 = 10 ÷ 2 = 5
5 * 3 = 15 ft^2
