PLS HELP THIS IS MY LAST 2 TEST QUESTIONS find the ​solution as ordered paired points

4x+5y=19 , x+5y=16 ​

−x+y=2 , 2x+y=8

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
