8x+4=28 question i want some one to solve this for me
Answer:
x = 3
Step-by-step explanation:
8x + 4 = 28
subtract 4 from both sides
8x + 4 - 4 = 28 - 4
8x = 24
divided both sides by 8
8x / 8 = 24 / 8
x = 3

PLEASE HELP!! Madison is monitoring the temperature over several hours. Her data is shown in the table. She draws a best-fit line with the equation y= -6.2+64 where x represents the number of hours that have passed and y represents the temperature.
Describe the meaning of the slope and the y-intercept in this context. Answer in complete sentences.
Using linear function concepts, we have that the interpretations are given as follows:
The slope of -6.2 means that the temperature falls 6.2 ºF every hour.The y-intercept of 64 means that the initial temperature was of 64 ºF.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we have that the function is given by:
y = -6.2x + 64.
Hence:
The slope of -6.2 means that the temperature falls 6.2 ºF every hour.The y-intercept of 64 means that the initial temperature was of 64 ºF.More can be learned about linear function concepts at https://brainly.com/question/24808124

She purchased a new lemon squeezer for $9.00.
The cost of the ingredients for each serving of lemonade is $1.50.
She will be selling each serving of lemonade for $2.25.
Write an inequality that represents the minimum number of servings of lemonade, x, Malika must sell for the money from her sales to exceed the total cost of making the lemonade.
Answer:
1.50x>2.25x+9.00
Step-by-step explanation:
Because the 1.50 has to go their because 2.25 is greater than 1.50, the 9.00 is at the end because their is not a variable. How to know were theh variables go is the each.

1. Emily wants to make 1, 000 paper cranes. She can make
eight cranes a day. If she has already made 304 cranes, how
many days are left till she makes the rest of the 1,000 paper
cranes?
CA
3-4
Answer:
87 days
Step-by-step explanation:
First if she already made 304 cranes and she makes 8 a day. Simply divide 304 by 8. You would then get 38. Next divide 1,000 by 8. You would get 125. You would subtract the total from how many days you need; 125, to how many days you already spent; 38. 125 - 38 = 87. 87 days are needed to make paper cranes.

I need help to find the measures and equation pls.
Answer:
Equation: 7x + 8x = 180
x = 12
∠CBA = 84
∠CFH = 96
Step-by-step explanation:
We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.
We know that the sums of two angles on a straight line are going to be equal to 180.
∠CBA = 7x
∠CFH = 8x
To find the value of x, we must do the following:
7x + 8x = 180
15x = 180
15x/15 = 180/15
x = 12
Now we just substitute to find the angle measures:
∠CBA = 7 · 12 = 84
∠ CFH = 8 · 12 = 96
Sarah said, "There is only one possible third side for a right triangle with two sides measuring 9 units and 15 units.'
Sarah's claim is not true. Give the two possible answers for the third side of the right triangle. Leave your answer
as a square root unless it can be simplified
The two possible answers for the third side of the right triangle are 6 and 24.
What is the triangle inequality theorem?
The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
So, a difference of two sides <x< sum of two sides, will give you the possible length of a triangle.
Sarah said, "There is only one possible third side for a right triangle with two sides measuring 9 units and 15 units.'
The two possible answers for the third side of the right triangle are;
[tex]\rm 15-9 < x < 15+9\\\\6 < x < 24[/tex]
The possible length of the third side of a triangle.
For checking the possible length:
15 + 9 > 7 (a+b>c)
9 + 7 > 15 (b+c>a)
7+ 15 >9(a+c>b)
Which satisfy the triangle inequality theorem.
Hence, the two possible answers for the third side of the right triangle are 6 and 24.

Find the mistake in the following set of steps in a student’s attempt to solve 5x+2≥x+2/5, for x. What is the correct solution set?
5x+2≥x+2/5
5(x+2/5)≥x+2/5 (factoring out 5 on the left side)
5≥1 (dividing by (x+2/5))
So, the solution set is the empty set.
Answer: x ≥ [tex]\frac{-2}{5}[/tex]
Step-by-step explanation:
I cannot see what the student did wrong in your question, so I solved for x in the equation...
[tex]5x + 2[/tex] ≥ [tex]x + \frac{2}{5}[/tex]
1. subtract x from both sides
4x + 2 ≥ [tex]\frac{2}{5}[/tex]
2. subtract 2 from both sides to isolate 4x
4x ≥ [tex]\frac{-8}{5}[/tex]
3. divide both sides by 4
x ≥ [tex]\frac{-2}{5}[/tex]

Answer:
Option A
Step-by-step explanation:
Rewriting the equation in terms of equalling L
P = 2L + 3WSubtract 3W on both sides.
P - 3W = 2L + 3W - 3W2L = P - 3WDivide 2 on both sides
2L/2 = (P - 3W)/2L = (P - 3W)/2⇒ Option A
