If n + 7 = 10, evaluate 2n - 2
O 3
0 17
4
6

Answers

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

[tex]n + 7 = 10[/tex]

Subtract 7 from both sides of the equation

[tex]n+7-7=10-7[/tex]

Simplify

[tex]n=3[/tex]

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

= 6 - 2

= 4

Therefore, the value of 2n - 2 is 4.

supppose v varies direcly as g, and v= 36 when g=4. Find v when g =11

Answers

Answer:

v = 99

Step-by-step explanation:

Given v varies directly as g then the equation relating them is

v = kg ← k is the constant of variation

To find k use the condition v = 36 when g = 4 , then

36 = 4k ( divide both sides by 4 )

9 = k

v = 9g ← equation of variation

When g = 11 , then

v = 9 × 11 = 99

How does x = 0.7x + 24 equal 80?

Answers

Answer:

x=0.7x+24

We move all terms to the left:

x-(0.7x+24)=0

We get rid of parentheses

x-0.7x-24=0

We add all the numbers together, and all the variables

0.3x-24=0

We move all terms containing x to the left, all other terms to the right

0.3x=24

x=24/0.3

x=80

And that's how you get 80

Step-by-step explanation:

i hope this helps. :)

Answer: x = 80

Step-by-step explanation:

80 - 24 = 56

A family owns two cars. One car gets 35 miles per gallon and the other car gets 27 miles per gallon. In one week the family drove a total of 480 miles and used 16 gallons of gas. Can you determine the number of miles the family drove each car? Can you explain

Answers

Answer:

the 35 gallon used 6 gallons of gas while the 27 mile car used 10.

Step-by-step explanation:

35 x 6 = 210

27 x 10= 270

270 + 210 = 480

Find the product.
(x-3)(x+5)

Answers

Answer:

x2+5x-3x-15=x2+2x-15

Step-by-step explanation:

(x)(x)=x2,(x)(5)=5x

(-3)(x)=-3x,(-3)(5)=-15

Answer: X^2 + 8x -15

Step-by-step explanation:

Use the foil method.

First, outer, inner, last

Multiply the first numbers inside each parenthesis. X*X = x^2

Next multiply the outer number in each parenthesis. X*5 = 5x

Then multiply the inner numbers of the parenthesis. -3*x= 3x

Finally multiply the last numbers in the parenthesis. -3*5 = -15

Now add all of these together

X^2 + 5x + 3x + -15

Combine like terms

X^2 + 8x -15

X can be solved from here, however it does not seem that you are asked to solve for x

how do you find the x and y intercepts from a table

Answers

The first step is to find the slope which is (y2-y1)/(x2-x1) and you can use any of these points. Next write the equation is point slope form which is y-y1=m(x-x1) using the slope and one of the points. Then you can simplify to write this is slope-intercept form and solve the x and y intercepts as given.
