Below are the steps to solve an equations
Step 1: IX - 4l+ 1 = 8
Step 2: IX - 4l = 8 - 1
Step 3: IX - 4l = 7
Which of the following is a correct next step to solve the equation? (1 point)
X-4 = -7
x+4=-7
x + 4 = 7
-x-4= 7
Answer:
x-4 = 7 , x-4 = -7
Step-by-step explanation:
IX - 4l+ 1 = 8
Subtract 1 from each side
IX - 4l = 8-1
IX - 4l = 7
Then separate into two equations, one positive and one negative
x-4 = 7 x-4 = -7

If 7/9x - 4/9x = 1/4 +5/12
what is the value of x?
Answer:
x=2
Step-by-step explanation:
subtract 7/9x -4/9x
3/9x= 1/4 +5/12
first change 1/4 to 3/12
then add 3/12 + 5/12
3/9x = 8/12
change 3/9x to 1/3x then to 4/12x
4/12x = 8/12
then mulitiply by the reciprical 12/4 on both sides
x = 2

No solutions
Step-by-step explanation:
y=7x+12;y=7x+2
Step: Solvey=7x+12for y:
y=7x+12
Step: Substitute7x+12foryiny=7x+2:
y=7x+2
7x+12=7x+2
7x+12+−7x=7x+2+−7x(Add -7x to both sides)
12=2
12+−12=2+−12(Add -12 to both sides)

Savannah paid $100 to join a music club. She then pays $1.00 per music download. Dominic joined a club for $25 but pays $2.50 per download. Determine the
number of downloads when the cost will be the same
Answer:
It would take 10 downloads
Step-by-step explanation:
Answer:
32 for Dominic and 5 for Savannah
Step-by-step explanation:
You can figure this out by first determining how many downloads Dominic has to make in order to have the total price equal to what Savannah paid just to join the club.
So Savannah paid $100 to join. Dominic only paid $25. So Dominic can spend $75 for downloads before he even gets up to what Savannah paid. Now you can figure out that it will take 30 downloads at $2.50 each to get to that $75.
You could say that Dominic is now equal to Savannah with both spending $100. Dominic would have made 30 downloads and Savannah would have 0. But I believe they want you to go a step further.
So now you just need to look at how many more downloads Dominic would have to make to get to an even full dollar amount. One more download would take him up to $102.50. A second additional download would take him to $105. Savannah would then only have 5 downloads for a total cost of $105 and Dominic would now have a total of 32 downloads for a total of $105.

In triangle ABC, the measure of angle B is 50 degrees. Select all possible values for the measures of A and C if ABC is an acute triangle. m\angle∠A= 58 degrees; m\angle∠C= 72 degrees m\angle∠A= 100 degrees; m\angle∠C= 30 degrees m\angle∠A= 80 degrees; m\angle∠C= 50 degrees m\angle∠A= 60 degrees; m\angle∠C= 70 degrees m\angle∠A= 90 degrees; m\angle∠C= 40 degrees m\angle∠A= 105 degrees; m\angle∠C= 25 degrees
Answer:
Step-by-step explanation:
Sum of angle in a triangle = 180°
<A+<B+<C = 180
Given <B = 50°
Substituting into the formula
<A+50+<C = 180
<A+<C = 180-50
<A+<C = 130°
Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°
The possible values of <A and <C that will be acute and give a sum of 130° are;
∠A= 58° and ∠C= 72°
∠A= 80° and ∠C= 50°
∠A= 60° and ∠C= 70°
You can see that all the Angles are less than 90° and their sum is 130°

HELP!!!
This is a geometry question!
Please give reasoning with your answer!
I can and will mark a "real" answer brainliest!
Step-by-step explanation:
For angle BDG
The common angles are: Angle DBG, Angle DGB
The common sides are: DG, GB, BD
And for angle AEF
The common angles are: Angle EFA, Angle EAF
The common sides are: EF, FA, AE
FOR the BGD triangle, all sides are connected together, so, all of them are common and the angles as well
And the same exact thing with triangle AEF also
Hope it helps!
Find the equation of the line
Y= __x + __
Answer:
Step-by-step explanation:
(0, -9) and (3,3)
(3+9)/(3-0) = 12/3 = 4
y + 9 = 4(x - 0)
y + 9 = 4x - 0
y = 4x - 9
Mrs. Stokes solved the equation shown below. Select the correct justification for each step shown.
-3(8x-2)=9-21x Original equation
8x-2=-3+7x
8x+1=7x
1=-x
-1=x
Answer:
Below in bold
Step-by-step explanation:
-3(8x - 2) = 9 - 21x
~Divide -3 to everything
8x - 2 = -3 + 7x
~Add 3 to both sides
8x + 1 = 7x
~Subtract 8x to both sides
1 = -x
~Divide -1 to both sides
-1 = x
Note that this isn't the most used way to solve equations because you would typically use distribution to simplify the left side.
Best of Luck!

The length of a rectangular window is 4 more feet than its width w. The perimeter of the window is 64 feet. Write an equation that could be used to find the demensions of the window and determine the length and width of the window.
Answer:
The length of the window is 18 ft and its height is 14 ft
Step-by-step explanation:
System of Equations
Let's call:
L: Length of the window in feet
W: Width of the window in feet
According to the first condition of the problem:
[tex]L = W + 4\qquad\qquad [1][/tex]
The perimeter of the rectangle is 64 feet. The perimeter is calculated as:
P = 2L + 2W =64
Dividing by 2:
[tex]L + W = 32\qquad\qquad [2][/tex]
The system of equations [1] and [2] can be used to find the dimension of the window.
Substituting from [1]
W + 4 + W = 32
Simplifying:
2W = 32 - 4 =28
Solving:
W = 28/2 = 14
Using [1]:
L = 14 + 4 = 18
The length of the window is 18 ft and its height is 14 ft
