          Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

A) Let's solve for x.  2x + 3y = 40

Step 1: Add -3y to both sides.

2x + 3y + -3y = 40 + -3y

2x = -3y + 40

Step 2: Divide both sides by 2.

\frac{2x}{2} = \frac{-3y + 40}{2}

x = \frac{-3}{2} y + 20

Answer : \frac{-3}{2} y + 20

~~~~~~~~~~~~~~~~~

B) Let's solve for x. 5x + 2y = 30

Step 1: Add -2y to both sides.

5x + 2y + -2y = 30 + -2y

5x = -2y + 30

Step 2: Divide both sides by 5.

\frac{5x}{5} = \frac{-2y + 30}{5}

x = \frac{-2}{5} y + 6

Answer : \frac{-2}{5} y + 6

Find the reference angle for the given angle. Show work
Katarina [22]
Answer: 44 degrees

=========================================================

Since the given angle -404 is not between 0 and 360, we add 360 to it to get:
-404 + 360 = -44

We add another 360 to that result
-44 + 360 = 316
now we have a value between 0 and 360

Rules:
* If the angle is between 0 and 90, we stop here and simply write down that value

* If the angle x is between 90 and 180, then we compute 180-x

* If the angle x is between 180 and 270, then we compute x-180

* If the angle x is between 270 and 360, then we compute 360-x

* Note in the three rules above, the order of subtraction is always (larger angle)-(smaller angle) = reference angle

* The reference angle has one segment on the x axis (aka the reference angle is adjacent to the x axis)

Based on that, we see that 316 is between 270 and 360, so we use the rule that
360-x
In this case, x = 316

So,
360-x = 360-316 = 44

The reference angle is 44 degrees and looks like what you see in the attached image.

A=12. B=16. C=?
11^2+16^2=C^2
121+256=C^2
377=c^2
The square root of 377 is bout 19 rounded or it's 19.41 but didn't think you wanted decimals
Hope this helps and is what u r looking for have a nice day

What is the answer to. 4x + 7<8
sukhopar [10]
First, subtract 7 on both sides. Now, you have 4x<1. Divide by 4 on both sides. Finally, you get x<1/4 (a quarter or said as one-fourth). So, x<1/4.
