Answer:

x + 2x = 108

Step-by-step explanation:

Let x be the number of oranges sold on Thursday

The number of oranges sold on Friday is twice as many or 2 times x, 2x

The total sold on  the two days is 108.  Add the number sold on Thursday and Friday together and let it equal to 108

x + 2x = 108

So lets say you sold ‘x’ number of oranges on Thursday.On Friday you sold double,therefore ‘2x’. And altogether combining the sales on Thursday and Friday you sold 108 oranges. Therefore if we add the number of oranges sold on Thursday and Friday we will get 108 oranges.
The equation will be: x(number of oranges sold on Thursday) + 2x( number of oranges sold on Friday) = 108 (total number of oranges sold altogether)
x + 2x = 108

Margaret gave the waitress $50 for 6 burgers. She received $9.80 in change. Each burger cost the same amount.

12. How much did the 6 burgers cost?

explanation please

Answers

Answer:  The 6 burgers cost $40.20 and each burger costs $6.70.

Step-by-step explanation:

If she gave $50  to the waitress and received back $9.80 as a change, then subtract $9.80 from $50  to find the original price of the 6 burgers.

50 - 9.80 = 40.20  This means the 6 burgers cost $40.20 and to find how the price of each burger, divide 40.20 by 6.

40.20/6 = 6.70

Step-by-step explanation:

The slope for number 18 would be 1/2 and the y intercept would be -6

The slope for 19 would be 2 and I cannot see the picture of the intercept correctly, but I’m assuming it is 6

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.

Answers

Answer:

Step-by-step explanation:

Given

There are 9 people going on a trip

They purchased coach tickets =$160

first class tickets =$1180

total budget to spend = $4500

Let coach tickets=X

So first class tickets=9-x

160x+1180(9-x)=4500

160+10620-1180x=4500

160x-1180x=4500-10620

-1020x=-6120

X=6120/1020

X=6

So answer

Coach tickets=X=6

First class tickets=(9-x)
