Can you guys please help me with this? I will give brainliest and 20 points if you help me.

Answer:
Step-by-step explanation:
1) a) equations: 3x+21 and 6x -60
b) value of x: 3x+ 21=6x-60 ( set them equal to each other because they are equal, then solve)
3x+21=6x-60
-3x=-81
x= 27
c) replace 27 in both equations to find the angle measure.
3(27)+21= 102
6(27)-60= 102
2) a) equations: 12x-18 and 8x+10
b) value of x: 12x-18=8x+10( set them equal to each other because they are equal, then solve)
12x-18=8x+10
4x=28
x= 7
c) replace 7 in both equations to find angle measure.
12(7) -18 = 66
8(7)+10= 66
angle measure: 66
3) a) equations: 7x+9 and 5x+3
b) value of x: to find value of x here, first know that the these two equations will add up to 180. So, set them up to be equal to 180.
7x+9+5x+3=180
Then solve.
12x+ 12=180
12x=168
x=14
c) angle measure: replace the 14 in the x of the two equations.
7(14) +9 = 107
5(14) +3= 73
add the two angle measure together to see if they add up to 180.
107 + 73 = 180 correct! :D

Ok so 1. I am in AP Calculus BC and I legit just fully learned how to do exponents (I had a rough year in algebra 1 lol) so don't feel bad. And 2. It's really simple. When you multiply exponents you so just add them so x^2 * x^3=x^5. This makes sense visually since x^3 is x*x*x and x^2 is x*x and when you multiply that out you get x*x*x*x*x. Division is also pretty simple and all you have to do is subtract them. (There is a reason for this but its not important but I'll explain it anyways. Basically when you divide it is the same thing as multiplying by a negative exponent so x^3 / x^2 = x.) When you have multiple variables all you have to do is combine like terms so if you have something like xy^2*xy^4 you would get (x^2)(y^6). As for your problems, here:

Answer:
8v + 9v - v
Step-by-step explanation:
Solving all options...
8v + 6v + 3v
=> 17v
3(v + 2) + 11v
=> 3v + 6 + 11v
=> 6 + 14v
2(4v + 8v)
=> 8v + 16v
=> 24v
8v + 9v - v
=> 16v
The last option is the only one that equals 16v, therefore, it would be the right answer.

Suppose a cheetah could travel 1.5 hours a top speed covering 111.9 miles how far could the cheetah travel in 1 hour
Answers
u get that by doing :
37.3(2) which equals 74.6
The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
A cheetah could travel for 1.5 hours at a top speed covering 111.9 miles.
The ratio of the number of miles to time = 111.9/1.5
With the same ratio, the number of miles x in 1 hour will be as,
x/1 = 111.9/1.5
x = 74.6 miles.
Hence "The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles:".

Answers
Answer:
No
Step-by-step explanation:
Here's what's going on: some person buying their furniture sees this sofa and it's $1200. That person sees theres a 1/3 off sale! They're happy and buy their sofa with a 20% off discount they got.
Now we have to find out if they should use the 20% off discount before or after adding the 1/3 off sale.
The answer is, they're both the same.
Say they add the 1/3 off sale discount and then use their 20% off discount. Find the 1/3 off sale: 1200 divided by 3 (because fractions are division problems) = 400. 20% of 400: 400 x 0.2 = 80. It's not just 80, because it's not an "only pay 20%" discount. 400 - 80 = 320. They'd pay $320 with this method.
This shows that using the 20% discount after the 1/3 off sale the customer spends $320.
Now let's calculate what happens if they use the discount after the 1/3 off sale. 20% of 1200: 1200 x 0.2 = 240. 1200 - 240 = 960. Now adding the 1/3 off sale: 960 divided by 3 = 320. They'd also pay $320 with this method.
If it's a short answer, you could just write something like, "No, both methods end up with the sales associate paying $320."

Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.
Answers
Answer:2
Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.
