Mary is five times older than julian. if the
sum of their ages is 42, how old is mary?

35

Step-by-step explanation:

M=5J

J=M/5

42=6J

42/6=7

Jullian is 7

7x5=35

Mary is 35

35+7=42

Mary is 35.

Step-by-step explanation:

An equation would be 5j + j = 42.

I used substitution by plugging in 7:

5(7) + 7 = 42

35 + 7 = 42

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

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.
