Answer:
-3(4a+3)+4(6x+1)
12a+(-9)+24x+5
12a-4+24x
Step-by-step explanation:
Because you can't add 12a & 24x bc they're different variables ( a & x ) & -9+5 you always minus it and it's going to be a negative because -9 is bigger than 5
solve for the equation 2x+9=3x

Solve the system of linear equations by elimination. 12x - 7y = -2 8x + 11y = 30
The solutions for the the system of equations are given as x = 1 and y = 2 respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
The given system of linear equations are as follows,
12x - 7y = -2 (1)
8x + 11y = 30 (2)
In order to solve by elimination, multiply equation (1) by 2 and (2) by 3 and then subtract to obtain,
2(12x - 7y) - 3(8x + 11y) = 2 × -2 - 3 × 30
=> -14y - 33y = -94
=> -47y = -94
=> y = 2
Substitute y = 2 in equation (1) to get,
12x - 7 × 2 = -2
=> 12x = -2 + 14
=> x = 12/12 = 1
Hence, the given system of linear equations is solved by elimination to give x = 1 and y = 2 respectively.

Answer:
m[tex] \angle[/tex]6 = 68°Step-by-step explanation:
From the question all the angles are on a a straight line which means the sum of their angles is 180 and one of the angles is 90°
So to find m [tex] \angle[/tex] 6 , add
m [tex] \angle[/tex] 5 and 90 and subtract the result from 180°
That's
m[tex] \angle[/tex]5 + m[tex] \angle[/tex]6 + 90 = 180
m[tex] \angle[/tex]6 = 180 - 90 - m[tex] \angle[/tex]5
m[tex] \angle[/tex]6 = 180 - 90 - 22
We have the final answer as
m[tex] \angle[/tex]6 = 68°Hope this helps you
In the question, a lines & angles diagram is provided, and we can see three angles labelled here. The angles are angle 5, angle 6 and a 90°.
GiveN,
Angle 5 = 22°One of them is 90°We have to find the measure of the missing angle 6...
All the three angles are lying on a staright line, so their collective measure or the sum of these 3 angles is equals to 180°.
➝ Angle 5 + Angle 6 + 90° = 180°
➝ 22° + Angle 6 + 90° = 180°
➝ Angle 6 + 112° = 180°
➝ Angle 6 = 68°
So, the measure of Angle 6:
[tex] \huge{ \boxed{ \bf{68 \degree}}}[/tex]

a −3=( a 1 ) 5 what is the value of a?
Answer:
A=[tex]\frac{-3}{4}[/tex]
Step-by-step explanation:
a−3=a1(5)
Step 1: Simplify both sides of the equation.
a−3=a1(5)
a+−3=5a
a−3=5a
Step 2: Subtract 5a from both sides.
a−3−5a=5a−5a
−4a−3=0
Step 3: Add 3 to both sides.
−4a−3+3=0+3
−4a=3
Step 4: Divide both sides by -4.
-4a/-4 = 3/-4
Your final answer is a=-3/4-2(4x + -4) - 3x - 2 =34
Answer:
x = -28/11
Step-by-step explanation:
-2(4x + -4) - 3x - 2 =34
Distribute
-8x+8 -3x-2 =34
Combine like terms
-11x +6 = 34
Subtract 6 from each side
-11x+6-6 = 34-6
-11x = 28
Divide each side by -11
-11x/-11 = 28/-11
x = -28/11
Answer:
x= -28/11
Step-by-step explanation:
Multiply -2 by 4x +4
That equals -8x+8
So the equation is now
-8x+8+3x -2 = 34
Now combine like terms
11x+6=34
Subtract 6 from both sides
11x=28
divide by 11 on both sides
x = -28/11
combining like terms with negative coefficients

Four boys, Kurt, Marcus, Nathaniel, and Steven, all collect baseball cards. They recently met to show each other some of the cards they had collected. Each boy brought a different amount of cards with them. Nathaniel brought twice as many as Steven, Marcus had four less than Nathaniel, but one more than Kurt. All together, they have 47 cars. How many cars did Kurt bring?
Steven's cards = x
Nathaniel's cards = 2x
Marcus' cards = 2x - 4
Kurt's cards = 2x - 5
Since the sum of the cards is equal to 47, let's set all the cards equal to 47
x + 2x + 2x - 4 + 2x - 5 = 47
Combine like terms.
7x - 9 = 47
Add 9 to both sides
7x = 56
Divide both sides by 7
x = 8
Let's plug 8 into x for Kurt's cards.
Kurt's cards = 2x - 5 = 2(8) - 5 = 16 - 5 = 11 cards.

How can u tell that 7.360 and 7.36 are equivalent decimals
Answer:
You can tell 7.360 and 7.36 are equivalent decimals because when you put a zero in the decimal places, it doesn't count as a number and it doesn't have a value. In conclusion, zero is just a placeholder. Therefore, if you have the zero or not it doesn't matter.
