3(x + 1) - 2x = -6 what’s the answer??
Answer:
x=−9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+1)−2x=−6
(3)(x)+(3)(1)+−2x=−6(Distribute)
3x+3+−2x=−6
(3x+−2x)+(3)=−6(Combine Like Terms)
x+3=−6
x+3=−6
Step 2: Subtract 3 from both sides.
x+3−3=−6−3
x=−9

Answer:
10
Step-by-step explanation:
1.25 each song
she bought 8 songs
1.25 x 8 = 10
10-20 = 10
How many degrees is arc PQ?
Answer:
Step-by-step explanation:
Arc PQ is 60°
Answer:
[tex]\boxed {\boxed {\sf Arc \ { PQ } = \ 60 \ degrees}}[/tex]
Step-by-step explanation:
The angle that forms arc PQ is a central angle, because the angle's vertex is at the center of the circle.
According to arc-angle relationships, the measure of a central angle is equal to the arc.
Since the central angle is equal to 60 degrees, arc PQ is also equal to 60 degrees.

Could you please help me with the step-by step? This problem is giving me trouble.
Write both sides as powers of 2. First,
1/2 = 2⁻¹
16 = 2⁴
so the equation can be rewritten as
(1/2)ˣ = 16²
(2⁻¹)ˣ = (2⁴)²
Recall that [tex](a^b)^c=a^{bc}[/tex], so that
2⁻ˣ = 2⁸
The bases are the same, so the exponents must be equal:
-x = 8
x = -8
An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 6.
Event B: The sum is not divisible by 4.
Write your answers as fractions.
find the are in millimeters plz.
Answer:
640 units squared
Step-by-step explanation:
First, the formula of a trapezoid is (a + b) x 2 divided by h
So, 40 + 24 = 64
64 x 20 = 1280
and 1280/2 = 640
Hope this helps!

The measure of an angle is 34.7°. What is the measure of its supplementary angle?
Answer:
Let the supplementary angle be x.
x+34.7°=180
or, x=180-34.7°
or, x=145.30°
:. x=145.30°

Write an equation in point-slope form for the line that passes through (3, 5) with a slope of 1.
Write an equation in point-slope form for the line that passes through (–2, 1) with a slope of 1/4 .
Answer:
y -5 = x-3;
y -1 = 1/4 (x+2)
Step-by-step explanation:
Point Slope form: [tex]y-y_{1} =m(x-x_{1}[/tex] , where m is the slope, and x1,y1 is the point.
1. y -5 = 1 (x-3)
y -5 = x-3
2. y -1 = 1/4 (x--2)
y -1 = 1/4 (x+2)
David's mother gave him $200.00 to buy some carrots at the Blue Market. She will be using the carrots to make juice for her church barbecue on Friday. At the market, David finds two vendors selling carrots. Vendor A has carrots for $40.00 per kilogram, and Vendor B has larger carrots for $50.00 per kilogram. From which vendor should David buy the carrot
Answer:
vendor A
Step-by-step explanation:
since they are going to be turned into juice, the size of the individual carrots is irrelevant. vendor A has a lower unit price

Find the area of the parallelogram.
Answer:
36 ft^2
Step-by-step explanation:
I) Find dimensions:
The base is 9 feet, and the height is 4 feet.
(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)
II) Find area:
Area = base x height
A = B x H
36 = 9 x 4
III) Find unit:
Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.

Answer:
a₂₀ = 69
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 15 - 12 = 3 , then
a₂₀ = 12 + (3 × 19) = 12 + 57 = 69
James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.
Answer: $339
Step-by-step explanation:
Given
The total length of the journey is 10 miles
fixed pledges are $300
variable pledges are $13 per mile
Point slope equation form is
[tex]\Rightarrow y=mx+c[/tex]
Here the total charge corresponds to y and miles walked corresponds to x
So, we can write
[tex]T=13\times m+300[/tex]
where,
[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]
for 3 miles distance
[tex]\Rightarrow T=3\times 13+300=\$339[/tex]

Answer:a neither perpendicular nor parallel.
Step-by-step explanation:
Parallel would have the same slope, meaning same constant with x and perpendicular would be like 1/2x and -2
For our safety, it is important that drivers recognize a stop sign immediately. Stop signs are made with exact side and angle measurements to form a regular octagon. They are red so they are easy to see. The three lines drawn below are straight lines. Lines a and b are parallel. a) The stop sign is a regular octagon, so the measure of ∠F must be 67.5°. What is the angle measure for ∠L? Describe the relationship between ∠F and ∠L. (1 point) b) What is the measure of ∠E? Explain how you know. (1 point c) Describe the relationship between ∠E and ∠K. What is the measure of ∠K? (1 point) d) What is the measure of ∠H? Explain. (1 point) e) What is the measure of ∠I? Explain. (1 point) f) Describe the relationship between ∠H and ∠L. (1 point)
Answer:
a is Angle L is 67.5 degrees. Angles F and L are opposite each other, yet the same angle degree.

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)
