Answer:
m1=105⁰, m2=75⁰
Step-by-step explanation:
m2=75⁰
m1+m2=180⁰
m1=180-75=105⁰
Answer:
C. (4,28)
Step-by-step explanation:
The substitution method requires you to input a specified number in place of a variable. In this case, the variable 'x' should be replaced by the number 4. Using the order of operations, we know that multiplication should be applied before subtraction. When we replace 'x' with 4, we get the equation 'y=8(4)-4'. Multiplying 8 and 4 gives us 32. If we subtract 4 from 32, we get 28. The answer ends up being 'y=28'.
That is the first part of our solution. What we are actually looking for is an ordered pair. We know ordered pairs are written in the form (x, y). First, we need to find the 'x'. The 'x' has been given to us from the beginning, it is 4. Next is the 'y'. This is what we needed to find using substitution. We ultimately concluded that the 'y' is equivalent to 28. Therefore our ordered pair is (4, 28), the letter choice C.
I hope this helped you and that I clearly elaborated on the answer choice.

Hi, I’m Lena and I’ll be here to answer your question with a good-quality answer. If there's something I can improve, let me know! ツ
♡ Let’s look at the main important things that will lead you in the correct path.
♥ <em>a </em>+<em> b</em> usually = <em>c!</em> Unless the book asks you to find a specific variable, you will most likely be looking for <em>c</em>.
♥ <em>A</em> = <em>bh</em>/2! This is the formula for the area of a triangle. You can also read this as A = base * height/2. The good thing about this formula is you don't need a picture. You can write it as <em>a</em> * b<em> </em>or <em>b</em> * <em>a!</em>
<em />
♡ Now, let's solve!
♥ Plug the numbers into the formula: 5*8/2.
♥ Solve! In this case, we do not need c: 40/2 = 20.
Your answer should be 20! Please do not hesitate to ask me any questions.
Answer:
x=-121
Step-by-step explanation:
.4(5+2x) -12 = .9x+2.1
Distribute the .4
2 + .8x -12 = .9x+2.1
Combine like terms
-10 +.8x = .9x +2.1
Subtract .8x from each side
-10 +.8x-.8x = .9x-.8x +2.1
-10 = .1x +2.1
Subtract 2.1 from each side
-10-2.1 = .1x +2.1-2.1
-12.1 = .1x
Divide by .1
-12.1/.1 = 1.x/.1
-121 =x
