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:
The total cost of 1 belt and 1 tie is $13 and $39 respectively.
Step-by-step explanation:
Given that,
The cost of 4 belts and 5 ties is $247.
Each tie costs 3 times as much as a belt.
Let the cost of a belt is x and that of a tie is y.
ATQ,
4x + 5y = 247 ...(1)
y = 3x ....(2)
Put the value of y from equation (2) in equation (1)
4x + 5(3x) = 247
4x + 15x = 247
19x = 247
x = 13
Put the value in equation (2)
y = 3x
= 3(13)
= 39
So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.
Answer:
180° - 110° = 70°. 70° represents the other two angles, so it needs to be divided in 2 to get the answer of 35°.
