What is the solution to equation. -x+2=3x+2
Answer:
x=0
Step-by-step explanation:
x+2=3x+2
Step 1: Subtract 3x from both sides.
x+2−3x=3x+2−3x
−2x+2=2
Step 2: Subtract 2 from both sides.
−2x+2−2=2−2
−2x=0
Step 3: Divide both sides by -2.
−2x
−2
=
0

Andy buys a new car for $23,540. He estimates that the car will decrease in value by about 5% each year. Which of the following functions best models this situation?
Answer: y=0.05x-23540
Step-by-step explanation: We turn 5% into a decimal which is 0.05 and we add x to it so we can pick how many years. Then we subtract 23540 because he has used that money to buy the car.

Y is directly proportional to c when y= 30 and x= 6. A) work out an equation connecting y and x.
B) work out the value of y when x= 12.
Answer:
I have the answer of Q B
Step-by-step explanation:
x = 6
y = 30
x = 12
y = ?

? = 5 ×12
? = 60
6. A manufacturer uses a mold to make a part in the shape of a triangular prism. The dimensions (1 point)
of this part are shown below.
Calculate the volume of the part. Round your answer to the nearest whole number.
A 108 mm
B 217 mm
C 454 mm
D 880 mm
Pls show work I really need help
Answer:
A 108 mm
Step-by-step explanation:
The computation is shown below:
As we know that
V = Bh
where
B denotes the area of the base
and h denotes the height of the prism.
Now
V = (1 ÷ 2 × 12.6 × 1.6) × 10.75
= 108.36 mm
= 108 mm
Hence, the option a is correct

What is the measure of x?
Answer:
Step-by-step explanation:
52+x=90
x=38
Answer:
x=38 degrees
Step-by-step explanation:
You know that x degree angle plus 52 degree angle have to equal 90 degrees. Therefore, the equation is x+52=90. You want to isolate x so you have to subtract 52 from both sides. The equation will look like x=90-52. Simplify this to get x=38. Therefore, x= 38 degrees.

The length of the y of the triangle is y = 96 inches
What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔXYZ
And , the measures of the sides of the triangle are
z = 75 inches
x = 26 inches
And , the measure of ∠Y = 135°
We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.
The Law of Cosines states that:
c² = a² + b² - 2ab cos(C)
where c is the side opposite angle C, and a and b are the other two sides.
In this case, we want to find the length of side y, which is opposite angle Y. So we can write:
y² = x² + z² - 2xz cos(Y)
Substituting in the given values, we get:
y² = 26² + 75² + 2(26)(75) cos(135°)
Simplifying, we get:
y² = 676 + 5625 - 2925√2
y² ≈ 9163
Taking the square root of both sides, we get:
y ≈ 95.76
Rounding to the nearest inch, we get:
y ≈ 96 inches
Hence , the length of y, to the nearest inch, is 96 inches

A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. Each small box of paper weighs 50 pounds
and ench large box of paper weighs 8o pounds. A total of 19 boxes of paper were
shipped weighing 1280 pounds altogether, Determine the number of small boxes
shipped and the number of large boxes shipped,
Answer:
Small boxes: 8
Large boxes: 11
Step-by-step explanation:
number of small boxes = x
number of large boxes = y
weight of boxes is represented by:
50x + 80y = 1280
Number of boxes is represented by:
x + y = 19
First, we'll solve for x in terms of y:
x = 19-y
Then we'll substitute that into the weight equation
50(19-y) + 80y = 1280
950 - 50y + 80y = 1280
30y = 330
y = 11
Now drop that numerical value into the number of boxes equation, and we'll get
x + 11 = 19
x = 8
Check the math in the weight equation:
50(8) + 80(11) =
400 + 880 = 1280

Step-by-step explanation:
Answer: The missing side is 48
Step-by-step explanation: The missing side is 48 because in this case, you got to do length time width, So the length is 6 and the width is 8, so now you multiply, which would be 6 times 8 is 48.
