Solve for v: -v+1=1 + 8v
AfilCa [17]

Answer: v=0

Step-by-step explanation:

Because....

Step 1: Simplify both sides of the equation.

−v+ 1= 8v + 1

Step 2: Subtract 8v from both sides.

−v+1 − 8v = 8v+1 − 8v

−9v + 1 = 1

Step 3: Subtract 1 from both sides.

−9v + 1 −1 = 1−1

−9v=0

Step 4: Divide both sides by -9.

\frac{-9v}{-9} = \frac{0}{-9}

v=0

Therefor, the answer is v = 0

* Hopefully this helps:) Mark me the brainliest:)!!!

Find the x and the area of the shape perimeter is 64.5​
Umnica [9.8K]

Answer:

x=8

A = 192

Step-by-step explanation:

The perimeter is the sum of the outer lengths

17.9 + 22.6 + 3x = 64.5

Combine like terms

40.5 +3x = 64.5

Subtract 40.5 from each side

40.5 +3x -40.5 = 64.5 - 40.5

3x =24

Divide each side by 3

3x/3 = 24/3

x = 8

The area of a triangle is given by

A = 1/2 bh

The base is 3x = 3(8) =24

and the height is 2x = 2(8) =16

A = 1/2 (24) * 16

A =192

A hypothesis test was used to see if less than 5% of all Americans would still drive to work if gas prices went above $10.00 a g
Kruka [31]

Answer:

The correct option is;

False

Step-by-step explanation:

Here, we note that the proportion of the test statistic which is used in the test is 5% and the P-value for the test is 0.03

The hypothesis test is meant to check if people will still drive to work when the gas prices are above $10.00 and the suggestion was that we can conclude that when the fuel price is above $5.00 everyone would still drive to work without a P-value for the test, hence we can not come to the stated conclusion.
