Solve for x: 2x + 4 - X=-3x + 12*
Your answer
Answer:
x = 2
Step-by-step explanation:
2x + 4 - x = -3x + 12
x + 4 = -3x + 12 ^ Combine like-terms
4x + 4 = 12 ^ Addition Property of Equality
4x = 8 ^ Subtraction Property of Equality
x = 2 ^ Division Property of Equality
Answer:
x = 2
Step-by-step explanation:
Solve for x:
2x + 4 - x = -3x + 12
Add 3x to both sides.
5x + 4 - x = 12
Combine like terms.
4x + 4 = 12
Subtract 4 from both sides.
4x = 8
Divide both sides by 4.
x = 2
Your final answer would be x = 2

What is the equation of the line shown?
Step-by-step explanation:
Hey there!
According to the figure, we find two points on graph. I.e (1,3) and (-2,-1) points respectively.
Now, Use double point formula for finding the eqaution.
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Keep all values.
[tex](y - 3) = \frac{( - 1 - 3)}{ (- 2 - 1)}(x - 1) [/tex]
~ Simplify it.
[tex](y - 3) = \frac{4}{3} (x - 1)[/tex]
[tex](y - 3) = \frac{4}{3} x - \frac{4}{3} [/tex]
[tex]y = \frac{4}{3} x - \frac{4}{3} + 3 [/tex]
[tex]y = \frac{4}{3} x + \frac{5}{3} [/tex]
Therefore, the equation of the line is y= 4/3x + 5/3.
Hope it helps...
Answer:
y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (1, 3) ← 2 point on the line
m = [tex]\frac{3+1}{1+2}[/tex] = [tex]\frac{4}{3}[/tex] , then
y = [tex]\frac{4}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 3 ), then
3 = [tex]\frac{4}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{4}{3}[/tex] = [tex]\frac{5}{3}[/tex]
y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← equation of line

Answer: 50
Step-by-step explanation:
Triangle LNK equals 180 degrees, we know that angle N is 58 degrees and angle NLK is 72 degrees, so we can just subtract 72 and 58 from 180 to get angle LKN. Hope that helps
Answer:
50°Step-by-step explanation:
Interior angles in the triangle sum to 180°
m∠NLK + m∠LNK + m∠LKN = 180°m∠LKN = 180° - (72° + 58°) = 180° - 130° = 50°Shivani is making greeting cards, which she will sell by the box at an arts fair. She paid $20 for a booth at the fair, and the materials for each box of cards cost $5. She will sell the cards for $7 per box of cards. At some point, she will sell enough cards so that her sales cover her expenditures. How many cards will that take?
Answer:
10 cards
Step-by-step explanation:
So to do this problem, you can make an equation where x is the number of cards sold, which would be:
7x - 20 - 5x = 0
This is because she makes $7 for every card she sells (so 7x), she paid $20 for the booth (so -20), it costs her $5 to make every card (so -5x), and you want to see how many cards it will take for her to cover everything she spent (so it would equal 0).
Then, solving:
[tex]7x-20-5x=0[/tex]
combine like terms
[tex]2x-20=0[/tex]
add 20 to both sides
[tex]2x = 20[/tex]
divide both sides by 2
[tex]x = 10[/tex]
This means the answer is 10 cards
Jamir is making cupcakes for the potluck. Each cupcake requires 3/4 cups of batter. How many cupcakes can he make?
Answer:
24 cupcakes
Step-by-step explanation:
Jamir is making cupcakes for the potluck. Each cupcake requires 3/4 cups of batter. How many cupcakes can he make?
In the question, we are not given the number of cups batter for a potluck. So we can assume
1 potluck = 18 cups of batter
3/4 cups of batter = 1 cup cakes
18 cups of batter = x cup cakes
Cross Multiply
3/4 × x = 18 × 1
x = 18 ÷ 3/4
x = 18 × 4/3
x = 24 cup cakes

Answer:
A: 43.55
Step-by-step explanation:
Place value can be defined as the numerical value representing a digit owing to its position in a number. Some examples of the various place values used in representing each digit are tenths, hundredths, thousandths, unit, tens, hundreds, thousands etc.
For example, in the number 43.55;
The place value of 4 is tens.The place value of 3 is units.The place value of 5 is tenths.The place value of 5 is hundredths.Rounding up to the nearest tenth simply means to have 1 significant figure after the decimal point.
Therefore, 43.55 to the nearest tenth is 43.6
Answer:
A
Step-by-step explanation:
The answer is A because 43.55 is rounded to 43.6. B is rounded to 43.7. C is rounded to 43.7. D is rounded to 43.5.
Clinton hosted an end-of-year party. He expected 5 guests, but 8 times as many showed up. How many people attended?
Answer:
41 people
Step-by-step explanation:
Clinton hosted an end-of-year party. He expected 5 guests, but 8 times as many showed up. How many people attended?
The amount of guest that showed up can be calculated as:
5 guest × 8 times the number of guests
= 40 guests
The number rod people that attended the end of the year party = 40 guest + Clinton
= 41 people

Liz earns a salary of $2,300 per month, plus a commission of 8% of her sales. She wants to earn at least
$2,800 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your
variable represents. Enter the commission rate as a decimal.
Answer:
Inequality: 0.08x + 2300 ≥ 2800
Liz needs to sell products of $6250 at least.
Step-by-step explanation:
Given that:
Per month salary of Liz = $2300
Commission = 8% = [tex]\frac{8}{100}}[/tex] = 0.08
Amount Liz wants to earn = $2800
Let,
x be the amount of sales.
0.08x + 2300 ≥ 2800
0.08x ≥ 2800 - 2300
0.08x ≥ 500
Dividing both sides by 0.08
[tex]\frac{0.08x}{0.08}\geq \frac{500}{0.08}\\x\geq 6250[/tex]
Hence,
Liz needs to sell products of $6250 at least.

Ms.Candos has 90 invitations to hand out. She hand out 42 of them. The rest will be handed out by 6 students. Each students will hand out an equal number of invitations. How many invitations will each student hand out.
Answer: 8 invitations each
Step-by-step explanation:
Ms. Candos has 90 invitations from which she will hand out 42 by herself. The number of invitations left will be:
= 90 - 42
= 48 invitations
There are 6 students to share out the rest. They will hand out:
= 48 / 6 students
= 8 invitations each
