PEMDAS is used for orders of operations
it shows an order how to solve this for example
(5-2)x4
so you would do the p first
P- parentheses
E- exponents
MD- Mulitplication and division
AS- Addition and subtraction
you would do it all in the pemdas order

What is the perimeter and area of the figure?

Rudiy27

Perimeter is the sum of all outside dimensions:

5 + 3 + 1 + 2 + 4 + 5 = 20cm

Area = (5 x 5) - (2*1) = 25 - 2 = 23 cm^2

leva [86]

93.75 because 5.75x7.50=43.125 and 6.75x7.50=50.625 and 50.625+43.125=93.748 and round it to the near test hundredth because it’s money and that’s 93.75

Tyler baked 702 cookies he sold them in boxes of 18 after selling all of the boxes of cookies for the same amount of each he ear

jenyasd209 [6]

Keywords:

<em>Cookies, boxes, sale, profit, unit cost </em>

For this case we have to bake an amount of 702 cookies, which were distributed in boxes of 18 for sale. Selling each box at the same price earned a profit of 136.50 dollars, you want to know the unit cost of each box of cookies.

Let $"x"$ be the number of boxes of cookies:

So, to know the number of boxes we divide 702 cookies among 18:

$x = \frac {702} {18}\\x = 39$

So, we have Tyler sold 39 boxes of cookies

Now, let $"y"$ be the cost of each box of cookies, to know the unit cost or sale price of the cookie boxes, we divided 136.50 dollars among 39 boxes of cookies, then:

$y = \frac {136.50} {39}\\y = 3.5$

Thus, the cost of each box was 3.5 dollars.

Answer:

The cost of a box is 3.5 dollars

Can someone help me solve for x on number 18 and explain how you did it thank you ;)

torisob [31]

Answer:

x = 19°

Step-by-step explanation:

Given that < (6x + 1)° + < (3x + 8)° are supplementary angles whose sum = 180°

6x + 1 + 3x + 8 = 180°

Add common terms:

9x + 9 = 180°

Subtract 9 from both sides:

9x + 9 - 9 = 180° - 9

9x = 171°

Divide both sides by 9 to solve for x:

$\frac{9x}{9} = \frac{171}{9}$

x = 19°

1. Use the given translation rule to find the image coordinates. Rule: (x, y) –(x - 4, y + 3) A(4,6) →A') and B(-2,3) -→B'().O A

artcher [175]

We have to translate the coordinates using the given rule.

The given rule is (x-4,y+3)

Now we have to translate the point A(4,6) using the given rule.

Then,

A' is (4-4,6+3)=(0,9)

Now the point B(-2,3) is to be transformed.

Then,

B' is (-2-4,3+3)=(-6,6)

Hence the answer is A'(0,9) and B'(-6,6)
