I will mark it as brainliest John, Yenni, Peter and Amber have a total of 1026 marbles. If Yenni gives away 60 of her marbles, she will have 1/4 of the marbles John has. If Peter buys another 150 marbles, he will have 1/2 the number of marbles John has. If Amber doubles what she has, she will have the same number of marbles as John. How many marbles did Yenni have? I will mark it as brainliest

184

Step-by-step explanation:

y + j + p + a = 1026

y - 60 = j/4 > y =  (j/4) + 60

p + 150 = j/2 > p = (j/2) - 150

2a = j > a = j/2

y = ?

y + p + j + a = 1026

(j/4) + 60 + (j/2) - 150 + j + (j/2) = 1026

(j/4) + j + j - 90 = 1026

(j/4) + 2j = 1116

9j/4 = 1116

9j = 4464

j = 496

y = (496/4) + 60 = 184

i'm not sure i quite understand, could you provide more information?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
