<h3>Answer:</h3>

24/25

<h3>Reviewing BODMAS:</h3>

Let's review the concept of BODMAS.

<u>BODMAS is the correct order we use solve a mathematical problem</u>.

=> B = Brackets
=> O = Order of powers or roots
=> D = Division
=> M = Multiplication
=> A = Addition
=> S = Subtraction

<h3>Solving the given expression.</h3>

<u>Now, let's solve the given expression using BODMAS.</u>

12 ÷ (2 + 23)2
=> 12 ÷ (25)2
=> 12 ÷ 25 x 2
=> 12/25 x 2
=> 24/25

<u>Hence, the solution is 24/25.</u>

Please help me out. I don’t understand this problem.. An equation of a line through (-7,-10) which is perpendicular to the line

nordsb [41]

Answer:

The Equation:

$y = \frac{1}{3}x - \frac{23}{3}$

The y-intercept:

$-\frac{23}{3}$

Step-by-step explanation:

<u>Things you need to know:</u>

Perpendicular mean opposite slope.

Need to know point slope form of a linear equation $y - y_1 = x(x - x_1)$

Ok, with that out the way, lets get started!

From the equation y = -3x + 2 we can see the slope, which is -3. We are asked to find an equation that is perpendicular to that slope so that means we need an opposite slope. To turn this slope to an opposite slope flip it and change the sign

-3 = $\frac{-3}{1} = \frac{1}{3}$

Now that we have our opposite slope, which is $\frac{1}{3}$ , we can find the equation the problem is asking us to solve.

We do this by using the point (-7, -10) and our new slope, which is $\frac{1}{3}$ and by using $y - y_1 = x(x - x_1)$

<u>Insert our point and slope into $y - y_1 = x(x - x_1)$ and solve for y</u>

$y - y_1 = x(x - x_1)$

$y - (-10) = \frac{1}{3}(x - (-7))$

$y + 10) = \frac{1}{3}(x + 7))$

<u>Work on the right side of the = sign</u>

Distribute 1/3 to x and 7

$y + 10 = \frac{1}{3}(x + 7))$

$y + 10 = \frac{1}{3}x + \frac{7}{3}$

<u>Bring the 10 over to the right side by adding a -10</u>

$y + 10 -10= \frac{1}{3}x + \frac{7}{3} - 10$

$y = \frac{1}{3}x + \frac{7}{3} - 10$

Do the math for $\frac{7}{3} - 10 = -\frac{23}{3}$

$y = \frac{1}{3}x - \frac{23}{3}$

<u>We are done.</u>

The Equation:

$y = \frac{1}{3}x - \frac{23}{3}$

The y-intercept:

$-\frac{23}{3}$

Sophia works in a clothing store and earns $40 per day. She earns an extra $5 for each outfit she sells. If Sophia wants to earn

andrew-mc [135]

Answer:

In order to find this answer, you will need to be able to make an inequality.

Step 1: Sophia makes $40 so start with that. 40

Step 2: Sophia also makes $5 per every outfit that she sells, so add that plus your variable (n). 40+5n

Step 3: Determine if Sophia wants to make more, equal to or more, less, or less than or equal to than what she wants to make per day. 40+5n *draw a greater than or equal to sign.

Step 4: Sophia wants to make more than or equal to what she makes per day. You will need to find what she wants to make more than. In this she wants to make more than or equal to $70.

Equation: 40+5n *greater than or equal to sign* $70

Shayla is baking muffins that require one-half cup vegetable oil. She only has one-third cup of vegetable oil left. How much mor

REY [17]

Well to make 1/3 and 1/2 equivalent fractions you need to find a common denominator. So it would be 6. 1/3 now becomes 2/6 and 1/2 becomes 3/6. So she would need 1/6 more cup of vegetable oil.
