Find the mixed number equivalent to the im<br> proper fraction 22/6
Naddik [55]

Answer:

3\frac{2}{3}

Step-by-step explanation:

Given the following question:

\frac{22}{6}

In order to convert a mixed number into an improper fraction we have to divide the numerator (in this case; 22) by the denominator (in this case; 6) to find your answer.

\frac{22}{6}
\frac{22}{6} \div2=\frac{11}{3}
\frac{11}{3}=11\div3=3\frac{2}{3}
=3\frac{2}{3}

Let three represent how many times 3 goes into 11, let 2 represent the remainder while of course keeping the denominator the same. Your answer is "3 2/3."

Hope this helps.

Solve the equation. identify any extraneous solutions. x=√6x+7
marshall27 [118]
In order to solve the equation we first need to put the condition:
6x+7>=0
x>= -7/6

We square the equation:
x^2=6x+7
x^2-6x-7=0
x^2+x-7x-7=0
x(x+1)-7(x+1)=0
(x-7)(x+1)=0
x1=7
x2=1

Both solutions meet the condition.

Mr. Yarmus purchased 3 cups of coffee for his friends. He paid $7.29 in yoyal, including and 8 percent sales tax. What was the c
Nonamiya [84]

Answer:

$2.25 price with per coffee without tax

Step-by-step explanation:

3 cups of coffee = $7.29 (with tax)

tax = 8% = 8/100 = 0.08 (NOTE: % means 1/100)

Total amount = a

Price for 3 cups without tax = p

tax of price for coffee = t

8% tax with coffee = p+p*0.08

How does the equation work, for example:

p = 10

p*0.08 = 0.8

p+p*0.08 = 10+0.8= 10.8 // price with tax

a = p + t

7.29 = p + 0.08p //Combine like terms

7.29 = 1.08p //Divide both sides by 1.08

7.29/1.08 = p

6.75 = p //Price of all 3 coffee without tax

6.75 = 3p //Finding price of 1 coffee without tax

6.75/3 = p

2.25 = p

Now finding total amount of per coffee with tax:

a = p + t

a = 2.25 + 2.25*0.08

a = 2.25 + 0.18

a = 2.43

Checking:

a = 2.43 //Price of per coffee with tax

a = 3(2.43) = 7.29 // Price of all 3 coffee with tax

//Hope it helps and it's right.
