Can someone help me solve this pls with work

Answer Monday

1) x = 7

2) t = 75

Answer Tuesday

1) n = 30

2) x = 3

Step-by-step explanation Monday:

For #1, you add 16 + 12 to get 28. Then you find out what times 4 = 28, and that's 7.

For #2 you subtract 17-2 to get 15. Then find out what times 1/5 = 15 and that's 75.

Step-by-step explanation Tuesday:

For #1, you subtract 10-7 to get 3, then find out what divided by 10 = 3 witch is 30.

For #2 you subtract 10-4 to get 6 and find out what times 2 equals 6 witch is 3.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
