Answer:

literal equations - 2 or more <u>different</u> variables

Step-by-step explanation:

● you can't solve a literal equation when more than one thing is unknown

● however you can rearrange the equation to solve for one of the unknown

Ex.

5x + 3y = 7 solving for x

-3y -3y

5x = 7 - 3y

÷ 5 = ÷ 5

x = 7 - 3y

---------

5

sorry for the slightly messy work

Solve and check <br> 2/3y =6 <br> A.1/9 <br> B.1/4<br> C.9<br> D.4
kotegsom [21]
\frac{2}{3}y=6\ \ \ \ |divide\ both\ sides\ by\ \frac{2}{3}\ /multiply\ by\ \frac{3}{2}/\\\\y=6\cdot\frac{3}{2}\\\\y=\frac{6}{1}\cdot\frac{3}{2}\\\\y=\frac{\not6^3\cdot3}{1\cdot\not2_1}\\\\y=\frac{3\cdot3}{1\cdot1}\\\\y=\frac{9}{1}\\\\\boxed{y=9}\leftarrow answer\ \boxed{C}

check:\\\\/put\ the\ value\ of\ y=9\ to\ the\ equation\ \frac{2}{3}y=6/\\\\\frac{2}{3}\cdot9=6\\\\\frac{2}{3}\cdot\frac{9}{1}=6\\\\\frac{2}{\not3_1}\cdot\frac{\not9^3}{1}=6\\\\\frac{2}{1}\cdot\frac{3}{1}=6\\\\2\cdot3=6\\\\\boxed{6=6}\leftarrow TRUE

Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72. Is Sasha correct in thinking that the mean accurately r
mezya [45]

Answer:

Yes, Sasha is correct. The mean amount she makes is $58.33 in a day.

Step-by-step explanation:

Given that Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72

Let us arrange in ascending order

32, 43,50,65,72,88

There are 6 entries hence 3rd and 4th are middle entries

Median = (50+65)/2=115/2=57.5

Sum of all entries = 350

No of entries =6

Mean amount = average = sum/6

=350/6

=58.33

Hence mean = 58.33

Out of 4 options we get I option only right

Yes, Sasha is correct. The mean amount she makes is $58.33 in a day.
