Answer:
Q1:14 Q2:8903.5
Step-by-step explanation:
I find that using equations to solve problems makes it a lot easier.
The first company's equation would be y=5743+225.75x because 5743 is the set fee and 225.75 is for each ton of sugar. The second company would be y=7500+100.25x for the same reasons.
So we need to find a value of x that works for each company and a value of y that is the same for the cost.
Now we combine them.
Solve for x:
5743+225.75x=7500+100.25x
-5743 -5743
225.75x= 1757+100.25x
-100.25x -100.25x
125.50x=1757
/125.5 /125.5
x=14
Therefore, for Q1, the answer is 14.
Now we solve for y by substituting x for 14.
5743+225.75(14)
5743+3160.5
8903.5
We can also check this with the other equation
7500+100.25(14)
7500+1403.5
8903.5
So therefore, the answer to Q2 would be 8903.5.

12*3^2+36 needs to be 540
12*9+36
9+36=45
12*45=540 so
12(3^2+36)
11.
32/2^3-4 needs to be 8
32/(2^3-4)
12.
2.3^2+9*4/2 needs to be 28.58
5.29+9*4/2
(5.29+9)*4/2=28.58
(2.3^2+9)*4/2
Hope this helps :)
Answer:
the lines arent parallel, so you cant use corresponding angles theorem
