Given 12−(−2) over a line 12−6÷2

We can use PEMDAS rule and solve the expression in the order as given below:-

1. Parentheses

2. Exponents

3. Multiplication

4. Division

5. Addition

6. Subtraction

Now solving for given expression:-

\frac{12-(-2)}{12-(\frac{6}{2})}\\\\=\frac{12+2}{12-3}\\\\=\frac{14}{9}

Solve the equation 14y+82=6x-20 for x if y is 25
Leni [432]

Answer:

x= 226/3 or 75.33333333333333333333333333333

Step-by-step explanation:

14y+82=6x-20

y=25

Sub y=25 into 14y+82=6x-20

14y+82=6x-20

14(25)+82=6x-20

Calculate as follows:

14(25)+82=6x-20

350+82=6x-20

432=6x-20

Add twenty to both sides:

432+20=6x-20+20

452=6x-0

452=6x

Divide both sides by 6

452=6x

452/6=6x/6

452/6=x

x= 226/3 or 75.33333333333333333333333333333

Timmy estimated he would spend $9 at the candy store. He went a little over-budget and spent $12. What was the percent error?
kap26 [50]
<h2>Answer :</h2>

  • Error (e) = 12 - 9 = $ 3

  • assumed value (a) = $ 9

\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}

  • \mathrm{ \% \: error =\dfrac{3}{9} ×100}

  • \mathrm{ \% \: error = \dfrac{1}{3} ×100}

  • \mathrm{ \% \: error = 33.33 \%}
