Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle \frac{a}{-7} - 7 = 5$ <u />

<u />

<u>Step 2: Solve for </u><em><u>a</u></em>

Addition Property of Equality: $\displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7$
[Simplify] Add: $\displaystyle \frac{a}{-7}= 12$
Multiplication Property of Equality: $\displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7$
[Simplify] Multiply: $\displaystyle a = -84$

<u>Step 3: Check</u>

<em>Plug in a into the original equation to verify it's a solution.</em>

Substitute in <em>a</em>: $\displaystyle \frac{-84}{-7} - 7 = 5$
[Frac] Divide: $\displaystyle 12 - 7 = 5$
Subtract: $\displaystyle 5 = 5$

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.

Which set of numbers is included in the solution set of the compound inequality? {–7, 5, 18, 24, 32} {–9, 7, 15, 22, 26} {16, 17

Vesnalui [34]

Answer:

{-7,5,18,24,32}

Step-by-step explanation:

Let's verify all cases to determine the solution to the problem.

CASE A) we have

-9,7,15,22,26

The number 22 is not included in the solution set of the compound inequality.

CASE B) we have

-7,5,18,24,32

The number 22 is not included in the solution set of the compound inequality.

CASE C) we have

16,17,22,23,24

The number 22 is not included in the solution set of the compound inequality.

CASE D) we have

18,19,20,21,22

The numbers 19,20,21,22 are not included in the solution set of the compound inequality.

The diagram below shows circle with radii OA

Finger [1]

Answer:

Length of arc AB = 4π

Step-by-step explanation:

Formula to get the arc length is given by,

Length of arc = $\frac{\theta}{360}(2\pi r)$

Here, θ = central angle subtended by the arc AB

r = Radius of the circle

By substituting the values in the formula,

Therefore, length of arc AB = $\frac{120}{360}(2\pi )(6)$

= 40π
