Answer:

$\Huge \boxed{169}$

Step-by-step explanation:

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, & subtract the numbers from left to right.

<h2>Please Excuse My Dear Aunt Sally!</h2>

<h2>PEMDAS</h2>

P- Parenthesis

E-Exponent

M-Multiply

D-Divide

A-Add

S-Subtract

First, multiply & divide numbers from left to right.

$\displaystyle 18\div2=9$

$\displaystyle 9*18=162$

Add & subtract numbers from left to right.

$\displaystyle 14+162-7$

$\displaystyle 162+14=176$

$\displaystyle 176-7=\boxed{169}$

So, the correct answer is 169.

To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .

14 + 18 ÷ 2 x 18 - 7

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.

NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression

Division

14 + 18 ÷ 2 x 18 - 7

18 ÷ 2 = 9

14 + 9 × 18 - 7

Multiplication

14 + 9 × 18 - 7

9 × 18 = 162

14 + 162 - 7

Addition

14 + 162 - 7

14 + 162 = 176

Subtraction

176 - 7

= 169

Illusion [34]

Answer:

Each jar has 12/7 cups of blueberries.

Step-by-step explanation:

To find out how many cups of blueberries per jar, we take the number of cups of blue berries and divide by the number of jars

12 cups/7 jars

12/7 cups of blueberries per jar

Each jar has 12/7 cups of blueberries.

in the function y-1=1/2(x-6)^2 what effect does the number 6 have on the graph, as compared to the graph y=x^2

butalik [34]

Answer: The graph is shifted 6 units to the right.

Step-by-step explanation:

It is important to remember that:

When $f(x-k)$ , then the function is shifted "k" units to the right.

Knowing this and given the quadratic parent function $y=x^2$ and the function $y-1=\frac{1}{2}(x-6)^2$ , you can observe that one of the transformations is the following:
