The number is 20. 20+10 (half of 20) + 4 (a fifth of 20) = 34
So there would be two equations
120=x+y
and
4850=45x+35y
We can now solve for each variable
y=120-x
plug it into the second equation...
4850=45x+35(120-x)
4850=45x+4200-35x
650=10x
x=65
Now plug in X
y=120-65
y=55
They are carrying 65 big boxes and 55 small boxes.

120=y+x
120=55+65
120=120

Answer:
Point-Slope form: 
standard form: 
Step-by-step explanation:
The standard form is given by: 
The point-slope form is given by: 
- <em>Let's call
as point
, and</em>
<em>point
as point
</em>
- <em>We also know that the slope
is given by
</em>
Let's find the slope:

1. So, point slope form can be written as:

2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:

<em>But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:</em>

<em>We can factor out a 3, so it becomes:</em>

So standard form is

8. 8(2nd power)divided by 2(4) +3(7)-1
8 to the 2nd power =16
2(4)=8
3(7)=21
16 divided by 8+21-1
8+21=29
29-1=28
answer 28
Answer:
D. angle 7 and angle 5.
Step-by-step explanation:
It is actually option 'D.' This is because angle 7 and angle 5 are vertical angles; vertical angles are always congruent.
