Answer:

B. 16

Step-by-step explanation:

Solve for s:

\longrightarrow 4(2s - 1) = 7s + 12

Expand out terms of the left hand side:

\longrightarrow 8s - 4 = 7s + 12

Subtract 7 s from both sides:

\longrightarrow (8s - 7s) - 4 = (7s - 7s) + 12

8s - 7s = s:

\longrightarrow s - 4 = (7s - 7s) + 12

7s - 7s = 0:

\longrightarrow s - 4 = 12

Add 4 to both sides:

\longrightarrow s + (4 - 4) = 4 + 12

4 - 4 = 0:

\longrightarrow s = 12 + 4

12 + 4 = 16:

\longrightarrow s = 16

Mrs Omar runs the school tennis club. She has a bin of tennis balls and rackets for every 5 tennis balls in the bin there are 5
Sav [38]

Answer:

x=y

Step-by-step explanation:

let x be the number of tennis balls and y the number of rackets.

-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

\frac{x}{y}=\frac{5}{5}=\frac{1}{1}=1

-Hence, for each one ball there is one racket, so;

x=y

-This relationship is linear in nature, a direct variation, and can be graphed as attached below:

Is 9 a solution to the equation 21=3p-5? Show work
Dmitry_Shevchenko [17]

Answer:

No

Step-by-step explanation:

21 = 3p - 5

<u>Step 1</u> : Add 5 on both sides

21 + 5 = 3p

26 = 3p

3p = 26

<u>Step 2</u> : Divide 3 on both sides

p = 26/3

Hence, the solution of the given equation is 26/3, not 9.
