A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?

Answers

I don't know your options, but here are some facts:
-all their options are sandwiches, and they all cost 5 dollars.

-This means that they can buy 150/5=30 sandwiches. This will make them use the entire budget!

-I would suggest cutting the sandwiches in half, then everyone gets three halves!

and if you say r for roast beef and t for tuna, you can write:

r+t=30.

and you can distribute is freely as long as both are 0 or bigger and their sum is 30!

Answer:

D.The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.

Rachel cut a length of rope 4 and 1/3 meters into two pieces. The length of one piece of rope is 2 and 1/2 meters. what is the length of the second piece of rope

Answers

just do     4 1/3 but first we need to make the fraction'd denominator the same. 6 is                               - 2 1/2  the common denominator. so:  4 2/6  =         3 8/6
              --------                                                   - 2 3/6          - 2 3/6
                                                                          ----------          --------
                                                                                                 1 5/6
1 5/6 meters long

Answer:

10 are 3/4 hr

4 are 1/2 hr

2 are 1/4 hr

Step-by-step explanation: we took 3/4 and multiplied x 10/1 = 30/4

we multiplied 1/2 x 4/1 =4/2      and we multiplied 1/4 x 2/1= 2/4

I converted 4/2 x 2/2 to give it the same common denominator as the other fractions 4/2 x 2/2=8/4

So 8/4 +30/4+2/4 = 40/4 divide this by 16 ( total number of cars)   But somehow I am not getting the answer of 5/8, 9/16, 3/4 or 1/2 that are to choose from for the answer.  40/4 = 10 and 10/16 is simplified by dividing by 2/2 = 5/8

Translate each verbal description into an algebraic expression. Then simplify Five-ninths of (3p+1) subtracted from one-thirf of q+p

Answers

Answer:

(1/3)q  - (4/3) p - 5/9

Step-by-step explanation:

Step one

Write the fractional form of the givens

(1/3)(q + p)

(5/9)(3p + 1)

Step Two

Write out the expression

(1/3)(q + p) - (5/9)(3p + 1)          Remove the brackets

(1/3)q  + (1/3)p - (5/9)*3p - 5/9 Combine the 2 p terms

(1/3)q  + (1/3 - 15/9 )p - 5/9       Reduce 15/9 down to 5/3

(1/3)q  + (1/3 - 5/3)p - 5/9         Combine what is inside the brackets

(1/3)q  + ( - 4/3)p - 5/9              Bring out the minus sign

(1/3)q  - (4/3) p - 5/9                 This should be your answer.
