Answer:
v=-1
Step-by-step explanation:
-3=-5-2v
-3+5=-2v
2=-2v
2/-2=-2v/-2
v=-1
Answer:
Answer:
v=−1
Step-by-step explanation:
Let's solve your equation step-by-step.
−3=−5−2v
Step 1: Simplify both sides of the equation.
−3=−5−2v
−3=−5+−2v
−3=−2v−5
Step 2: Flip the equation.
−2v−5=−3
Step 3: Add 5 to both sides.
−2v−5+5=−3+5
−2v=2
Step 4: Divide both sides by -2.
−2v

The trapezoid below has been enlarged by a scale of 1.5. What is the area of the enlarged trapezoid?
Answer:
New area by scale of 1.5 = 81 in²
Step-by-step explanation:
Given:
Current area = 36 in²
Find:
New area by scale of 1.5
Computation:
New area by scale of 1.5 = Current area x (scale factor)²
New area by scale of 1.5 = 36 x (1.5)²
New area by scale of 1.5 = 36 x (2.25)
New area by scale of 1.5 = 81 in²
Answer:
B.
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.
We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
Therefore, the area of the enlarged trapezoid would be and option B is the correct choice.
Jessica school bus stop is 60 yards from her house.For a normal school week, how many feet will Jessica walk to and from the bus stop?
A 300 feet
B 600 feet
C 900 feet
D 1,800 feet
winner gets 100 points
Answer:
d
Step-by-step explanation:
school is only 5 days a week and if she walks 60 yards to the bus stop and 60 yards back from the bus stop than she walks a total of 120 yards a day
120 x 5 =600 the answers are in feet so we need to convert to feet and to do that we need to multiply by 3
600x3=1800
so she walks 1800 feet in a normal school week

For the question, calculate the slope of a line that passes through the points given. Remember to reduce all fractions to lowest terms.
(-14, 18), (-16, 14)
Answer:
the answer is 2 or 2/1 hope this helps
Answer:
In fraction form, the slope is 2/1.
Or, the slope is just 2.
Step-by-step explanation:
Using the equation:
m =
y2 - y1 /
x2 - x1
Plug in the x and y points and solve.
note: m = slope in slope intercept form, y - mx + b
y2 = 14 y1 = 18
x2 = -16 x1 = -14
14 - 18 / -16 -(-14)
-4 / -2
Simplified: -2 / -1
In fraction form, the slope is -2 / -1, or 2/1 because either way works.
Or, the slope is just 2.
Hope this helps! If you have any additional questions, please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe, and please mark brainliest! :)
2(1 – x) > 2x HELP ASAP!!! I CANT FIGURE THIS OUT
This is the same as saying x < 0.5 since 1/2 = 0.5
====================================================
Work Shown:
2(1-x) > 2x
2*1 + 2*(-x) > 2x ..... distribute
2 - 2x > 2x
2 > 2x+2x .... adding 2x to both sides
2 > 4x
4x < 2 ..... flip both sides; flip the inequality sign
x < 2/4 ..... dividing both sides by 4; see note below
x < 1/2
Note: We do not flip the inequality sign here because we are dividing both sides by a positive value. The inequality sign would only flip if you divide both sides by a negative number.

Find the length of CD.
PLEASE HELP quickkkk
Answer: see below
Step-by-step explanation:
Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.
So, 1) AB/BC = AJ/JI
2.5/2.25 = AJ/1.8
AJ = 2.5* 1.8 / 2.25
AJ = 2
2) BC/CD = JI / IH
2.25/CD = 1.8/1.2
CD = 2.25 * 1.2 / 1.8
CD = 1.5
3) CD/DE = IH/HG
1.5/3.5 = 1.2 / HG
HG = 1.2 * 3.5 / 1.5
HG = 2.8
4) For GF, we should use "Pythagoras Theorem"
h² = a² + b²
GF² = 6.5² - 6²
GF² = 42.25 - 36
GF = √6.25
GF = 2.5
5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2
P = 26.55
6) Area = 1/2 * b * h
A = 1/2 * 9.65 * 10.3
A = 49.70
Hope this helps!

What is the value of log3 81?
O 2
O 3
O 4
O 5
4 is the value of log₃ 81.
We have,
A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
The equation may be changed to read:
x = log base 3 of 81.
81 being equivalent to 3 to the power of 4, we get the following:
x Equals log base 3 of 34.
We may reduce this to: Applying the rule that log base an of ab = b
4 = x
By answering the above question, we may infer that We may reduce this equation to: Applying the rule that log base an of ab = b, 4 = x.
Hence, x = 4.

What is the geometric mean between 3 and 10
Answer:
So for the geometric mean, you would multiply the two numbers and put them under a radical
Step-by-step explanation:
3 times 10= 30
=[tex]\sqrt{30}[/tex]
The solution is : the geometric mean between 3 and 10 is √30.
What is geometric mean?The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.
here, we have,
Given: two numbers 3 and 10

Joshua has a 32 ounce flavored water. He drinks 30 ounces. Enter the percentage of ounces Joshua has left of his flavored water. Round here answer to the nearest hundredth.
Answer: 6.25%
Step-by-step explanation:
From the question, we are informed that Joshua has a 32 ounce flavored water and that he drinks 30 ounces.
The amount of water he has left will be:
= 32 - 30
= 2 ounces
The percentage of ounces Joshua has left of his flavored water will then be:
= 2/32 × 100
= 1/16 × 100
= 6.25%

Area of the rectangle is given by the polynomial function A(x)=2x^2+18x. If the width of the rectangle is 2x what is the length?
The length of the rectangle is x + 9 whose width is gives as 2x.
To find the length of the rectangle, we need to express it in terms of the width.
Given:
width of the rectangle is 2x.
The formula for the area of a rectangle is
A = length × width.
As, the polynomial function for the area:
[tex]A(x) = 2x^2 + 18x[/tex]
So, set up the equation:
[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]
Substituting the given width = 2x in above equation gives
[tex]2x^2 + 18x = 2x * length[/tex]
Dividing both sides of the equation by 2x:
x + 9 = length
Therefore, the length of the rectangle is x + 9.
