Hi!

(the green numbers on the image are the step numbers)

We can solve this using PEMDAS.
I wrote out how I solved it in the image, and here I will go more into detail:

Step 1
Write out the equation

Step 2
Put in the variables

Step 3
Solve:
Parentheses - Multiply

Step 4
Parentheses - Subtract

Step 5
Multiply

Step 6
Add
There's your answer! :)

The answer is 42

Hope this helps! :)

Substitute the values of a and b

8(3) + 6[2(5)-7]

You have to multiply the numbers in the parenthesis with the adiacent one.

24 + 6(10-7)

24+6(3)

24+18

42

A) All triangles add up to 180° so when given two angles, add those up and subtract them from 180° . That will give you the missing angle.

3-5) When you do A above, and receive the measurement of angle 1, it will also equal 2 and you can repeat A for missing angle 3

6-8) Find the missing angle next to 1, and then subtract that from 180°. That number is the answer for 1. 2 is 55 as its a complimentary (i think thats the right term) angle. Which means it is on the opposite side of an angle. I don't remember how to find 3 however, its been a few years since I've done triangles.

Debbie cut a cord into sixths . She used five of the to make necklaces . She used equal lengths of the remaining cord for each o

Brut [27]

So she used $\frac{5}{6}$ of the cord to make necklaces.
$1- \frac{5}{6} = \frac{1}{6}$

She splits the $\frac{1}{6}$ length into 4 equal lengths.
To divide a fraction by a fraction, you multiply it by its reciprocal.
$\frac{1}{6} ( \frac{1}{4})$
$=\frac{1}{24}$

She used $\frac{1}{24}$ of the original chord to make each bracelet.

A line that passes through (-1, 6) and the origin

zmey [24]

Answer: The equation is y = -6*x

Step-by-step explanation:

I suppose that we want to find the equation for a line that passes through the point (-1, 6) and the origin (remember that the origin is the point (0,0))

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If this line passes through the points (x₁, y₁) and (x₂, y₂), then the slope of the line is equal to:

a = (y₂ - y₁)/(x₂ - x₁)

Now we know that our line passes through the points (0, 0) and (-1, 6), then the slope is:

a = (6 - 0)/(-1 - 0) = 6/-1 = -6

Then our equation is something like:

y = -6*x + b

To find the value of b we can use the fact that this line passes through the point (0, 0).

This means that when x = 0, y is also equal to zero.

If we replace these values in the equation we get:

0 = -6*0 + b

0 = b

Then our equation is:

y = -6*x
