if you distribute and simplify:
4x-12 = 12+4x-8
4x-12 = 4x+4
-12 ≠ 4
Answer:
[tex]x = - \frac{1}{3} [/tex]
Step-by-step explanation:
1) Simplify 2 - 6 to -4.
[tex]2x \times - 4 = 4(3 + 1 \times x - 2)[/tex]
2) Simplify 1 × x to x.
[tex]2x \times - 4 = 4(3 + x - 2)[/tex]
3) Simplify 3 + x - 2 to x + 1.
[tex]2x \times - 4 = 4(x + 1)[/tex]
4) Simplify 2x × -4 to -8x.
[tex] - 8x = 4(x + 1)[/tex]
5) Divide both sides by 4.
[tex] - 2x = x + 1[/tex]
6) Subtract x from both sides.
[tex] - 2x - x = 1[/tex]
7) Simplify -2x - x to -3x.
[tex] - 3x = 1[/tex]
8) Divide both sides by -3.
[tex]x = - \frac{1}{3} [/tex]
Therefor, the answer is x = -1/3.
if 1/4x +2y= 11/4
and - 6y - x = 7, what is
half of y?
Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ -x - 6y = 7
2y = 18
y = 9
half of 9 = 4 1/2

HELP WILL MARK YOU BRAINLIEST
Answer:
30
Step-by-step explanation:
The first term of an arithmetic sequence is
42. The rule an = Q71-2 + 8 can be used to find
the next term of the sequence.
Answer:
i dont know i so sorry i thout ii know but i dont so sorry
Step-by-step explanation:
Answer:
The rule shows that each term is 8 more than the previous term, so the common difference is 8.The explicit formula of an arithmetic sequence is the initial term plus (n – 1)d.The explicit rule for this function can be found by substituting 42 for a1 and 8 for d.The explicit rule for the sequence is 42 + (n – 1)8.
Solve the system of equations by using substitution.

David is twice as old as Rachel. Peter is 5 years older than David and Kim is 3 years
younger than Rachel. Which represents the order of the children by age, from youngest
to oldest?
The increasing order from youngest to oldest is Kim, Rachel, David, Peter
What is increasing order?Increasing order is a method of arranging numbers from the smallest value to the largest value. The order goes from left to right.
Given that, David is twice as old as Rachel. Peter is 5 years older than David and Kim is 3 years younger than Rachel.
Since, David is older than Rachel, and the next sentence says Peter is older than David. It says Kim is younger than Rachel, so we can say Peter is oldest than comes David and then Rachel and the youngest member is Kim.
Hence, the increasing order from youngest to oldest is Kim, Rachel, David, Peter

- Drake and troy are building models. For every 10 pieces
Drake puts together, Troy puts together 6 pieces. If Troy
puts together 18 pieces, how many pieces does Drake
put together?
Answer:
30
Step-by-step explanation:
Looking at the question we will notice that every 6 that Troy puts together Drake makes 10 so its simple, Troy makes 18 so we divide that by 6 meaning we get 3. We then get 3 and multiply it by 10, Thus 30 shall be our answer.

What is the answer for this eqation? 20-3x=9-7x
Answer:
x = - 11/4
Step-by-step explanation:
20- 3x = 9 - 7x
Add 7x to both sides
20 - 3x + 7x = 9 - 7x + 7x
20 + 4x = 9
Now,Subtract 20 from both sides
20 -20 + 4x = 9 - 20
4x = -11 {Divide both sides b 4}
x = -11/4
Answer:
= -11/4
Step-by-step explanation:
Rearrange terms
−3+20=9−7
− 3 + 20 = − 7 + 9
Subtract 20 from both sides of the equation
− 3 + 20 = − 7 + 9
− 3 + 20 − 20 = − 7 + 9 − 20
Simplify / Subtract the numbers
− 3 = − 7 − 1 1
Add 7 7x 7x to both sides of the equation
− 3 = − 7 − 1 1
− 3 + 7 = − 7 − 1 1 + 7
Simplify / Combine like terms
4 = − 1 1
Divide both sides of the equation by the same term
4 = −11
4/4 = -11/4
Simplify / Cancel terms that are in both the numerator and denominator
= -11/4

What is an equation of the line that passes through the points
(6,1) and (7,2)? Put your answer in fully reduced form.
Answer (assuming it can be in slope-intercept form):
y = x - 5
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the x and y values of the given points into it. Then, solve:
[tex]m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1[/tex]
2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or [tex]y-y_1 = m (x-x_1)[/tex]. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.
[tex]y-1 = 1(x-6)\\y -1 = x-6\\y = x -5[/tex]
millicent earned $435 last year in interest. If $3000 was invested at a certain rate of return and $4500 was invested in a fund with a rate that was %2 lower, find the 2 rates of interest
Answer:
7% and 5%
Step-by-step explanation:
The computation of the two rates of interest is shown below;
The interest rate for $3,000 be x%
And, for $4,500 the interest rate is (x -2%)
The total interest earned is
= x% of $4,500 + (x - 2)% of $4,500
So, the two rates of interest is
x% of $4,500 + (x - 2)% of $4,500 = $435
30x + 45(x - 2) = $435
30x + 45x - 90 = $43
75x = $25
x = 7%
x - 2 = 7 - 2
= 5%

Write the equation of the line parallel to y= 5/4x + 5/4 That passes through the point (-2,3)
Answer:
[tex]y=\frac{5}{4}x+\frac{11}{2}[/tex]
Step-by-step explanation:
y = (5/4)x + (5/4)
Slope = 5/4
Parllel lines have same slope
Slope of the line parallel to this line = 5/4
(-2 , 3)
y -y1 = m(x -x1)
y - 3 = (5/4)(x - [-2])
[tex]y -3 =\frac{5}{4}(x +2)\\\\y - 3 =\frac{5}{4}x + 2*\frac{5}{4}\\\\y -3 =\frac{5}{4}x + \frac{5}{2}\\\\y =\frac{5}{4}x + \frac{5}{2}+3\\y =\frac{5}{4}x+\frac{5}{2}+\frac{3*2}{1*2}\\\\y=\frac{5}{4}x+\frac{5}{2}+\frac{6}{2}\\\\y=\frac{5}{4}x+\frac{11}{2}[/tex]
