Answer:
The last one, the first one, the first one
<h2>
Step-by-step explanation:</h2>
We need to think, 28 / 42 = x / 54.
We need to do a proportion for this problem!
First, line up both fractions, then put a equal sign between both fractions.
28 / 42 = x / 54.
We multiply in a diagonal and then we divide by the one without a diagonal.
28 and 54 are a diagonal.
We multiply both numbers!
54 x 28 = 1,512.
Then, we divide by 42.
1,512 / 42 = 36.
Therefore, x = 36.

Step-by-step explanation:
y = mX + c
3y = -3x - 1
divide by 3
y = -x -1/3
slope = -1 of this line and parallel lines
Answer:
There are 37 white marbles.
Step-by-step explanation:
Let the white marbles be represented as w.
Let the yellow marbles be represented as y.
The bag contains both white marbles and yellow marbles which add up to 46 marbles. This means that:
y + w = 46 ___________(1)
The number of white marbles is 1 more than 4 times the number of yellow marbles. This means that:
w = 1 + 4y ___________(2)
First, we find y by putting (2) in (1), thereafter, we find w:
=> y + 1 + 4y = 46
y + 4y = 46 - 1
5y = 45
y = 45 / 5 = 9 marbles
=> w = 1 + 4(9)
w = 1 + 36 = 37 marbles
There are 37 white marbles.
