Use picture above.<br><br> Write the ratio. Please explain what the ratio means.
PIT_PIT [208]

1) 2:5 ratio

This is a fairly simple process, you count how many of each and then put them in order the way the question asks.

So there are 5 cans and 2 bottles. The question asks "bottles to cans" so the correct answer HAS to be 2:5, NOT 5:2.

2) 3:1

There is 1 spoon and 3 forks. The question asks "forks to spoons" so the correct answer HAS to be 3:1, NOT 1:3

Solve for y<br> 1/2y + 1 = 2
alina1380 [7]

Hey there!

ORIGINAL EQUATION:

1/2y + 1 = 2

SUBTRACT 1 to BOTH SIDES:

1/2y + 1 - 1 = 2 - 1

CANCEL OUT: 1 - 1 because it give you 0

KEEP: 2 - 1 because it help solve for the y-value

NEW EQUATION: 1/2y = 2 - 1

SIMPLIFY IT!
1/2y = 1

MULTIPLY 2 to BOTH SIDES

1/2y * 2 = 1 * 2

CANCEL out: 1/2 * 2 because it give you 1

KEEP: 1 * 2 because it give you the y-value

NEW EQUATION: y = 2 * 1

SIMPLIFY IT!
y = 2


Therefore, your answer is: y = 2


Good luck on your assignment & enjoy your day!

What is the factorization of the trinomial below? 4x2 + 20x - 24
Ivenika [448]
Hey there!

4x^{2} +20x -24
We can first factor out the 4 (bring it outside the parenthesis)

4( x^{2} +5x - 6)
Now have a closer look between the parenthesis, because this expression can be factored as well. We're looking for two different numbers with a product of -6 and a sum of 5. Hence, we find the numbers 6 and -1

4(x-1)(x+6)
