Well let's call the smaller of the numbers n
We know that n + (n + 2 4/8) = 7 2/8
In simpler form, 2n + 2 4/8 = 7 2/8
Subtract 2 4/8 from both sides to get
2n = 4 6/8
Divide both sides by 2 to isolate n, so
n = 2 3/8
To find the larger number, add 2 4/8 to the smaller number, getting 4 7/8
So the numbers are 2 3/8 and 4 7/8
36,630 & 36,629 because if you add 6,930+29,700=36,630 so if you go back from 630 you get 629 so it's 36,30 & 39,629

Answer: Choice B) 15x, -x, and 33x</h3>
=========================================================
Explanation:
Like terms are when we have the same variable attached to the number. The variable must have the same exponent as well.
For instance, 2x and 3x are like terms since they both have x. Something like 7x and 8x^2 are not like terms because the exponents don't match.
Terms like 17y and 17 are not like terms because the second term doesn't have a y tacked on. If you have nothing but constants, then those are like terms as they all have the same thing in common in that they don't have a variable attached to them.
With all this in mind, we can see that 15x, -x, and 33x is the answer since each have x as part of the variable term. The exponents are all the same (all being 1).
Answer:
y = -1/2 ( x − 4 )^2 + 8
Step-by-step explanation:
First find the vertex form
y = a ( x − h )^ 2 + k where ( h,k) is the vertex
The vertex is ( 4,8)
y = a ( x − 4 )^2 + 8
Now we need to determine a
Pick a point on the graph (0,0)
and substitute this point into the equation
0 = a ( 0 − 4 )^2 + 8
0 = a (16) +8
-8 = 16a
-8/16 =a
-1/2
y = -1/2 ( x − 4 )^2 + 8
1. there are 11 letters total and 1 m so 1:11
2. true
3. 10 total marbles. 2 black so 2/10 = 1/5
4. 3 x 3 x 5 = 45
5. 15 marbles so 6/15 black 4/15 blue = 8/75
6. 15 marbles so 5/15 red 5/15 x 5/15 = 1/9
7. 3/10 x 4/9 = 2/15
8. Drawing a club or a black card
9. Drawing a king or a queen
