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

How many like terms are in the expression?

Answers

‘Like terms’ means things with the same letters.

Your question is: 14x - 14y + 7 - x + z + 2x

As 14x, -x and 2x all have the same letter; they are like terms.

The answer would be 3, as there are only 3 like terms in your question.

I hope this made sense, if you need any more help or need me to explain further just ask! :)
The correct answer would be 3

What is the difference between (-2)^6 and -2^6 power? I know the first one is 64 and the second one is -64.

Answers

9514 1404 393

Answer:

 The treatment of the minus sign is different.

Step-by-step explanation:

An exponent signifies repeated multiplication. According to the order of operations, exponentiation is done first, before any multiplication or subtraction.

  (-2)^6 = (-2)·(-2)·(-2)·(-2)·(-2)·(-2) = 64

  -2^6 = -(2·2·2·2·2·2) = -64

The first answer is in positive and the second one is negative

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)

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
