You park in a garage 3 floors below ground level. Then you get in the elevator and go up 12 floors. What floor do you get off the elevator?

Answer:

Step-by-step explanation:

100(a+6-a)/a=12

100(6)/a=12

600=12a

a=50

Answer:

yes they are equivalent. if you simplify -21/-56 by dividing it by 3 you will get -7/-21 which equals to 7/21

Answer and Step-by-step explanation:

To simplify algebraic expressions, follow the basic rules:

1. Remove brackets or parentheses by multiplying factors;

2. Use exponent rule to remove grouping, if terms have exponents;

3. Add or subtract like terms;

4. Combine constants;

In the expressions above, there only constants and scientific notations, i.e., exponents elevated on a base 10. So, to simplify, we multiply the numbers and add the exponents:

(4.27 x 10⁸)(9.2 x 10⁻⁵) = 39.28 x 10³

(6.96 x 10⁵)(8.43 x 10⁻²) = 58.67 x 10³

[tex]\frac{(7.25.10^{5})(9.36.10^{-7})}{(7.95.10^{-2})(4.13.10^{-3})}=[/tex] 2.07 x 10³

[tex]\frac{(8.32.10^{4})(9.67.10^{1})}{(7.56.10^{11})(5.79.10^{-8})}[/tex] = 1.84 x 10²

[tex]\frac{(1.89.10^{4})(5.92.10^{3})}{(2.74.10^{-2})(4.67.10^{2})}=[/tex] 0.875 x 10⁷

All the exponents are positive, which means, comma "moves" to the right.

The numbers arranged from least to greatest will be

1.84 x 10² < 2.07 x 10³ < 39.28 x 10³ < 58.67 x 10³ < 0.875 x 10⁷

Answer:A

Step-by-step explanation:

Because yes

Answer:

x = 9

Step-by-step explanation:

5x * 135 = 180

180 - 135 = 45

5x = 45

5 ÷ 5 = 0

45 ÷ 5 = 9

X = 9

Answer:

y = 17/6 x - 40/3

Step-by-step explanation:

Slope-intercept form: y = mx + b

First, let's find the slope:

slope formula: (y2-y1) divded by (x2-x1)

(4, -2) and (8, -9)

(-9 - 8) divded by (-2 - 4) = 17/6

We found m, now we have to find b.

The new equation: y = 17/6 x + b

Insert any of the two points, in this case, I'll insert (4, -2)

-2 = 17/6 (4) + b

-2 = 68/6 + b

b = -2 - 68/6

b = -40/3

Overall equation: y = 17/6 x - 40/3

Answer: 144 minutes

Step-by-step explanation:

Based on the information that has been given in the question, the minutes that the slower pipe alone can use in filling the tank can be denoted by y minutes.

Therefore, the faster pipe will fill it in 1/3 × x = x/3 minutes.

Therefore,

1/x + 3/x = 1/36

4/x = 1/36

x = 36 × 4

x = 144

The number of minutes taken by the slower pipe will be 144 minutes.

Answer:

a

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

No, because

the first function if you further calculate you have

y= 3(x +5) is y = 3x+15 ; since you have to distribute

the second function if you have to translate is y=3x+5 because if you read it out loud the equation now you will say y equals 3 times x plus 5 like was given

Answer:

Slope= 0  Y-intercept= (0,2)

Step-by-step explanation:

Answer:

(- 2, 1 )

Step-by-step explanation:

Given the 2 equations

- 3x - 4y = 2 → (1)

3x + 3y = - 3 → (2)

Adding the 2 equations term by term will eliminate the x- term, that is

0 - y = - 1

- y = - 1 ( multiply both sides by - 1 )

y = 1

Substitute y = 1 into either of the 2 equations and solve for x

Substituting into (2)

3x + 3(1) = - 3

3x + 3 = - 3 ( subtract 3 from both sides )

3x = - 6 ( divide both sides by 3 )

x = - 2

solution is (- 2, 1 )

Answer:

x = -2 and y = 1

Step-by-step explanation:

3x + 3y = -3, x + y = -1,  x = -y -1

-3(-y-1) - 4y = 2, 3y + 3 - 4y - 2 = 0

-y +1 = 0, y = 1

x + y = -1, x + 1 = -1, x = -2

Answer:

x = 51 degrees

Step-by-step explanation:

Keep in mind, the angles of a triangle add up to 180 degrees.

A flat line also equals 180 degrees.

First, we should find the lower left angle. We know that 117 plus that angle is going to be 180, since it's a flat line.

180 - 117 = 63

Now, we just need to find angle x. (All 3 of our angles should add up to 180, knowing this, we can put it in an equation)

63 + 66 + x = 180

Then, you solve for x:

(63+66) + x = 180

129       + x = 180

-129             -129

               x = 51

Hope this helps :)

Answer:

4^2 + 6^2 = x^2

Step-by-step explanation:

Pythagorean theorem is used. Solve for x.

[tex]envo \: car = 65 + 0.10(m)[/tex]

[tex]freedom \: ride = 80 + 0.05(m)[/tex]

//

I honestly don't know how to do a)

//

[tex]envo \: car = 65 + 0.10(250) = 90.00[/tex]

[tex]freedom \: ride = 80 + 0.05(250) = 92.50[/tex]

He should rent from Envo Car because it would be cheaper.

Answer: Choice A

The area of the rectangle is equal to the number of unit squares that cover the rectangle. The area of the rectangle is 24 square units.

=====================================================

Explanation:

Imagine drawing equally spaced grid lines to subdivide the rectangle. This splits the rectangle into smaller squares. In this case, each little square is 1 square unit. Having 24 of these squares leads to a total area of 24 square units.

We could have 8 rows and 3 columns of these squares to get 8*3 = 24 total. Or we could have 6 rows and 4 columns to get 6*4 = 24. Another configuration is 12 rows and 2 columns which leads to 12*2 = 24.
