Elimination method x+4y=1 -3x-5y=-10

Mathematics

nevsk [136]2 years ago
3 0

Answer:

x = 5 and y = 1 is the answer.

Step-by-step explanation:

(-5)(x+4y=1)

(-4)(-3x-5y=-10)

-5x + -20y = -5

12x + 20y = 40

———————

7x + 0 = 35

7x= 35

7x/7 = 35/7

x = 5

subtitution:

x= 5

x + 4y = 1

5 + 4y = 1

4y = 1 - 5

4y = 4

4y/4 = 4/4

y = 1

Ms. Chen is planning to take her camp group on a field trip to Pottery Bayou where each person will create her own piece of art
erica [24]

Answer:

1. C=21x.

2. C=(8x+104).

Step-by-step explanation:

Let the number of people in the group be x. Denote the total cost as C.

1. If the regular cost is $21 per person, then the total regular cost for x people is C=21x.

2. If the special cost is $8 per person, then the total special cost for x people is \$8x. There is an additional $104 fee for a private room, thus the total special cost is C=(8x+104).
