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

o 0 If a triangle has angle measurements of 60 and 70°, what is the measure of the third angle? What kind of triangle is this? Acute, Right, or Obtuse? Explain how you solve this problem.
Answer:
→ 50°
→ Acute triangle
Step-by-step explanation:
the measure of the third angle = 180 - (60 + 70) = 180 - 130 = 50°
definitions=======================================
Acute angle : it’s an angle that measures less than 90°.
Acute triangle: it’s a triangle with three acute angles.
………………………………………………………………………………………………
The measures of the angles in our triangle are respectively 60° , 70° , 50°
Thus ,it’s an acute triangle .
Consider this system of equations.
p=2np=2np=2n
p−5=1.5np−5=1.5np−5=1.5n
What value of nnn makes the system of equations true?
The values of n and p which makes the system of equations true are 10 and 20 respectively.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have system of equation:
p=2n and
p−5=1.5n
Put p = 2n in the other equation.
2n - 5 = 1.5n
2n = 1.5n +5 (add 5 on both sides)
0.5n = 5 (subtract 1.5n on both sides)
n = 10 (divide by 0.5 on both sides)
Put n = 10 in the equation p = 2n
p = 2(10) = 20
Thus, the values of n and p which makes the system of equations true are 10 and 20 respectively.

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

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

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
Malika is making lemonade to sell at a school fundraiser:
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.
She purchased a new lemon squeezer for $9.00.
The cost of the ingredients for each serving of lemonade is $1.50.
