Solve the equation: 4x - 9x + 11 = -24. When you guys solve this, be sure to show your work.
jolli1 [7]

Answer:

4x - 9x + 11 = -24

-5x + 11 = - 24

-5x = -24 - 11

-5x = -35

-5x/-5 = -35/-5

x = 7

What are the first 6 terms for this arithmetic equation?
Ipatiy [6.2K]

Answer:

3, - 2, - 7, - 12, - 17, - 22

Step-by-step explanation:

To find the first 6 terms substitute n = 1, 2, 3, 4, 5 into the formula, that is

t(1 + 1) = t(1) - 5 ⇒ t(2) = 3 - 5 = - 2

t(2 + 1) = t(2) - 5 ⇒ t(3) = - 2 - 5 = - 7

t(3 + 1) = t(3) - 5 ⇒ t(4)  = - 7 - 5 = - 12

t(4 + 1) = t(4) - 5 ⇒ t(5) = - 12 - 5 = - 17

t(5 + 1) = t(5) - 5 ⇒ t(6) = - 17 - 5 = - 22

THE QUESTION IS DOWN BELOW.<br>major points when given branliest
emmainna [20.7K]

The ratios are Surface area ⇒ 4 : 25 Height ⇒ 2 : 5 and Volume ⇒ 8 : 125

<h3>How to determine the ratios?</h3>

The scale factor is given as:

m : n = 2 : 5

For the area, we take the square of the ratios.

i.e.

Area = 2^2 : 5^2

Evaluate

Area = 4 : 25

For the volume, we take the cube of the ratios.

i.e.

Volume = 2^3 : 5^3

Evaluate

Volume = 8 : 125

The given scale factor can be used for the height of the model and the original bicycle

Hence, the ratios are

Surface area ⇒ 4 : 25

Height ⇒ 2 : 5

Volume ⇒ 8 : 125
