hram777 [196]

Answer:

The answer is A, 86 sections.

Step-by-step explanation:

Step one : Add the 130 feet on to the 300 feet to find the new length of the fence.

130 + 300 = 430

Step two : find how many 5 foot sections he has now, divide 430 by 5.

430/5 = 86

Mr. Jackson can divide the new fence into 86 5-foot sections.

the catering company is setting the table for a big event that will host 764 people when they set up the tables they need 2 fork
BARSIC [14]
Given:
child = 2 forks
adult = 5 forks
total number of forks = 2992
total number of people = 764

c + a = 764
2c + 5a = 2992

find the value of c using the 1st equation.

c = 764 - a

substitute c in the 2nd equation by its value

2c + 5a = 2992
2(764-a) + 5a = 2992

1528 - 2a + 5a = 2992
1528 + 3a = 2992
3a = 2992 - 1528
3a = 1464
3a/3 = 1464/3
a = 488

c = 764 - a
c = 764 - 488
c = 276

child = 276 ; adult = 488

2c + 5a = 2992
2(276) + 5(488) = 2992
552 + 2440 = 2992
2992 = 2992
