Answer:
1 pound of expensive chocolate2 pounds of other chocolateStep-by-step explanation:
Let e represent the number of pounds of expensive chocolate in the bag. Then (3-e) is the amount of the other chocolate. The total cost of the bag will be ...
6.00e +4.50(3 -e) = 15.00
1.50e = 1.50 . . . . . . collect terms, subtract 13.50
e = 1 . . . . . . . . . . . . .divide by 1.50
1 pound of expensive chocolate is used; 2 pounds of other chocolate is used.
Divide. Give the quotient and the remainder

Answer:
C
Step-by-step explanation:
18's factors are 2 * 3 * 3
The two 3s can reduce the result further. sqrt (2 * 3 * 3)
square root 18 = 3*sqrt(2)
There are two sides with this length. Their total is 3sqrt(2) + 3sqrt(2) = 6√2
The perimeter is the sum of all three sides = 6 + 6√2

F 15 = 5 – 22
Answer:
Step-by-step explanation:
2x - 5 = 15
Bringing like terms on one side
2x = 15 + 5
2x = 20
Option B is the correct answer
Answer:
b) 2x = 20
c) 2(x - 5) = 15
D) 2x - 20 = 0
Explanation
2x - 5 = 15
2x = 15 + 5
2x = 20
x= 20/2
x= 10
a) 2x = 10
x= 10/2
x= 5 (which is not correct)
b) 2x = 20
x= 20/2
x = 10 (which is correct )
c) 2(x- 5) = 15
2x - 10 = 15.
2x = 15 +10
2x = 20
x = 20/2
x= 10 ( which is correct)
d) 2x - 20 = 0
2x = 20
x= 20/2
x= 10 ( which is correct)

Answer:
The the linear equation in point-slope form is
[tex]y-3 = -2 (x-4)[/tex]
Step-by-step explanation:
Given
slope = m = -2point (4, 3)We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here:
m is the slope(x₁, y₁) is the pointsubstituting the values m = -2 and the point (4, 3) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-3 = -2 (x-4)[/tex]
Thus, the the linear equation in point-slope form is
[tex]y-3 = -2 (x-4)[/tex]
Note: This equation could be further simplified to write it in the slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so writing the equation in the slope-intercept form
[tex]y-3 = -2 (x-4)[/tex]
[tex]y-3 = -2x+8[/tex]
[tex]y=-2x+8+3[/tex]
[tex]y=-2x+11[/tex]
Thus, the equation is the slope-intercept form is
[tex]y=-2x+11[/tex]What is the midpoint of KL

The correct proportion that can be used to find x is 8 / 24 = 12 / x
The corresponding sides of the figures are taken into consideration.
The base of the smaller trapezium 12 ft correspond to the base of the bigger trapezium x ft. Therefore the ratio can be established as
12 / xThe other leg of the smaller trapezium 8 ft correspond to the other leg of the bigger trapezium 24 ft. Therefore, the ratio can be establish as
8 / 24The ratio must be equal to each other to prove the similarity . Therefore,

Mr. Chen is painting one wall of a room in his attic. He needs to detemine the area of the wall so he will know how much paint he will buy. The drawing below shows the dimensions of the wall.
Part A: Given the drawing, what is the area of the wall?
The area of the wall is
square feet.
Part B: If one quart of paint will cover 22 square feet, how many whole quarts will Mr. Chen need to buy?
He will need to buy
whole quarts.
Area of the figure
= (area of rectangle) + (area of triangle)
= (8 × 10) + (½ × 4 × 8)
= 80 + 16
= 96

(x - 6)² = (x - 6)(x - 6)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 6) - 6(x - 6) ← distribute both parenthesis
= x² - 6x - 6x + 36 ← collect like terms

Which equation is equivalent to x + 8 = 21? (x + 8) × 4 = 21 (x + 8) × 4 = 21 ÷ 4 (x + 8) × 4 = 21 × 2 (x + 8) × 4 = 21 × 4
Answer:
(x + 8) × 4 = 21 × 4
Explanation:
x + 8 = 21
21 - 8 = 13
(13 + 8) × 4 = 21 × 4
21 × 4 = 21 × 4
84 = 21 × 4
84 = 84

Answer:I think its 68
Step-by-step explanation:
Answer:
The measure of angle N is 68 degrees.
Step-by-step explanation:
Since this shape is a parallelogram, opposite angles will be equivalent. So to start, set (6x - 2) equal to (4x + 36).
— 6x - 2 = 4x + 36
Next, subtarct the 4x from both sides of the equation as well as add 2 to both sides of the equation an simplify.
— 6x - 4x - 2 + 2 = 4x - 4x + 36 + 2
— 2x = 38
Now, divide both sides of the equation by 2 to find the value of x.
— 2x/2 = 38/2
— x = 19
Finally, substitute 19 for every x in the original equation. Simplify.
— 6(19) - 2 = 4(19) + 36
— 114 - 2 = 76 + 36
— 112 = 112
We now know that these two angles are 112 degrees. If a parallelogram's angles must add up to 360 degrees, then subtract 112 twice from 360 to find the combined total angle measure of N and Q. Then divide that number by 2 to find the measure of N.
— 360 - 112 - 112 = 136
— 136/2 = 68
The measure of angle N is 68 degrees.
Which of the following transformations always preserve the orientation of a figure?
1- Translations
2- Rotations
3- Reflections
4- None of them
Answer:
Translation
Step-by-step explanation:
Translation is when something moves or slide. Orientation refers to the way it is facing or turned.
The required given statement is Reflections is transformations always preserve the orientation of a figure.
What are transformations?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
The given statement is which transformations always preserve the orientation of a figure.
According to given question we have
Reflection is a type of transformation in which the given image is flipped across a line of reflection to create the transformed image. In this transformation, dimensions of the figure is always preserved.
In a translation, the preimage and image have the same orientation. In a rotation, the orientation of the preimage is changed. Both are rigid transformations.
Therefore, the required given statement is Reflections is transformations always preserve the orientation of a figure.

Answer:
A) 55 + x ≤ 100
B) 55 + x ≤ 70
Step-by-step explanation:
A Explanation - Inequalities use signs < , > , ≤ , and ≥. We also know you have 100 seconds to beat the level, so you have to solve it in 100 or less, which tells us the 55 + the time left (x) must be less than or equal to 100. Solved will be attached.
B Explaination -
Like A, you can use the same setup, but switching a value. You already have the 55, you need 70. Or less points to ≤, same as before, so you can keep it the same, except with the 70 instead of the 100. Solved attached.
