Answer:
C. Distribute 4 to (6 - x).
Step-by-step explanation:
Person above is right.
Juan’s first step should be C. Distribute 4 to (6 – x).
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a b + a c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
We are given an equation as;
4(6 – x) = 12
Here Juan wants to solve the equation, using the Distributive Property.
thus, 4(6 – x) = 12
First step is to distribute 4.
4(6) – 4(x) = 12
Then solve;
24 - 4x = 12
x = 3
Hence, Juan’s first step should be C. Distribute 4 to (6 – x).

Write 2x+3y=6 in slope-intercept form.
pls help me!!
Answer:
Y= [tex]\frac{-2x+6}{3}[/tex]
Step-by-step explanation:
slope intercept formula is
Y=mx+b
Now we want the y isolate so in this case we just subtract 2x on both sides
3Y=6-2x
or in more better terms
3y=-2x+6
Now we want the 3 isolated so we divide 3 on both sides
and you’ll get
[tex]\frac{-2x+6}{3}[/tex]

Which inequality correctly matches the graph?
Answer:
The inequality correctly matches the graph is -2 < x < 4 ⇒ B
Step-by-step explanation:
From the given figure
∵ There is a segment drawn from -2 to 4
∴ The starting point of the inequality is -2
∴ The ending point of the inequality is 4
∵ The endpoints of the segments are white circles (not shaded)
→ That means the signs of inequality without sign =
∴ The values of x are between -2 and 4
∴ The inequality is -2 < x < 4
∴ The inequality correctly matches the graph is -2 < x < 4

10. Rewrite into slope-intercept form 7x + y = 25
To write in slope-intercept form, you first need to get y by itself. To do this, subtract 7x from both sides of the equation.
Doing this gets you: y = 25 - 7x
Now that y is by itself, remember that slope-intercept form looks like this: y = mx + b
So, let's switch the right side.
y = -7x + 25
Slope intercept form is: y = -7x + 25
Rules for y in Slope-Intercept form:
y must be positive
y must be by itself (so, not 2y, or anything with it... just y)

CW: A sheet measures 20cm by 50cm. How many sheets
required to cover a wall of size 4m and 5 m?
!
Answer:
200 sheets are required
Step-by-step explanation:
We need to calculate the area of both the sheets and the wall
Mathematically,
area of a rectangle = l * b
Area of the sheet = 20 * 50 = 1,000 cm^2
100cm = 1 m
so the area of the wall is 400 by 500 = 200,000 m^2
To know the number of sheets, we now divide the area of the wall by that of the sheet
Mathematically, that will be;
200,000/1,000 = 200 sheets

The sum of three numbers is 76. The third number is eight less than the first. The second number is two times the third. What are the numbers?
Step-by-step explanation:
Read the poem. excerpt from “Spring” by Christina Rossetti Frost-locked all the winter, Seeds, and roots, and stones of fruits, What shall make their sap ascend That they may put forth shoots? Tips of tender green, Leaf, or blade, or sheath; Telling of the hidden life That breaks forth underneath, Life nursed in its grave by Death. Which line from the poem contributes most to a hopeful tone? "Telling of the hidden life" "Frost-locked all the winter," "Life nursed in its grave by Death." "What shall make their sap ascend"
The numbers are 25, 34, and 17.
Let x be the first number, y be the second number, and z be the third number. We know that x + y + z = 76, z = x - 8, and y = 2z.
Substituting the second and third equations into the first equation, we get x + 2(x - 8) + (x - 8) = 76.
Simplifying the right side of the equation, we get 4x - 24 = 76.
Adding 24 to both sides of the equation, we get 4x = 100.
Dividing both sides of the equation by 4, we get x = 25.
Substituting x = 25 into the equation z = x - 8, we get z = 25 - 8 = 17.
Substituting x = 25 and z = 17 into the equation y = 2z, we get y = 2 * 17 = 34.
Therefore, the numbers are 25, 34, and 17.

Answer:
B. PK = 15, RJ = 9
Step-by-step explanation:
RQ = 3
PQ = 5
✔️In ∆JKL, Q is the centroid. According to the centroid theorem, thus:
⅓(RJ) = RQ
⅓(RJ) = 3
Multiply both sides by 3
RJ = 3*3
RJ = 9
✔️Also, based on the centroid theorem,
⅓(PK) = PQ
⅓(PK) = 5
Multiply both sides by 3
PK = 5*3
PK = 15

What is the perimeter of triangle ABC?
Answer:
18 units
Step-by-step explanation:
Using the midpoint theorem, the perimeter of the triangle formed by joining the midpoints of the original triangle is exactly half the size in perimeter
What we mean in this case is that the perimeter of BAC IS two times the perimeter of EDF
perimeter of EDF is the sum of all the sides = 2 + 4 + 3 = 9
So the perimeter of BAC is 2 * 9 = 18

Diane sold some stuffs at a garage sale. She spent one-half of the money she made on a new bicycle. Next, she spent one-half of what was left on a portable stereo. If Diane had $40.00 left, how much money did she make from the garage sale
Answer:
$160
Step-by-step explanation:
Diane sold some stuffs at a garage sale.
Let the total value of the money Diane made = x
She spent one-half of the money she made on a new bicycle.
Amount spent on a Bicycle = 1/2 × x = 1/2x
Next,
Amount left
= x - 1/2x = 1/2x
She spent one-half of what was left on a portable stereo.
Amount spent spent on Portable stereo
= 1/2 × 1/2x
= 1/4x
If Diane had $40.00 left,
Hence:
The fraction of what was left is calculated as:
= x - (1/2x + 1/4x)
= x - (3/4x)
= 1/4x
Hence:
1/4x = $40
We can find the value of x now.
1/4 × x = $40
x/4 = $40
x = $40 × 4
x = $160
Therefore, the amount she made from the garage sale is $160
