Answer:
y = 4/3
x = 2
Step-by-step explanation:
2x − 3y = 2
x = 6y − 5
x - 6y = -5
2x − 3y = 2 | ×1 |
x - 6y = -5 | ×2 |
2x − 3y = 2
2x - 12y = -10
____________--
9y = 12
y = 12/9
y = 4/3
2x − 3y = 2
2x - 3(4/3) = 2
2x - 4 = 2
2x = 2 + 4
2x = 6
x = 6/3
x = 2
7 - (c + 18) > 0
-1 (c + [11])
~Now multiply each of the sides by -1~
c + 11 < 0
~Then , subtract 11 from each of the sides that you're working with~
c < -11
~Lastly, "c" becomes a negative~
-c - 11.0 > 0
Therefore your answer would have to be:
c < -11
Answer:
250
Step-by-step explanation:
If 15 is 6% multiplying it by 16.66666666666667 will make it 100%
15 x 16.66666666666667 = 250
Another way to do this is divide by 6 and multiply by 100
First cake requires x cups of flour.
Second cake: x + 1/2
Third cake: 2x
2 pound bag has 8 1/2 cups and it's exactly what Carly needs, so we can write it down as:
8 1/2 = x + x + 1/2 + 2x
8 1/2 = 2x + 1/2 + 2x
8 1/2 = 4x + 1/2 / - 1/2 (both sides)
8 = 4x / ÷ 4 (both sides)
<u>x = 2</u>
Doublecheck:
2 + 2 + 1/2 + 2 * 2 =
= 2 + 2 + 1/2 + 4 =
= 4 + 1/2 + 4 =
= 8 + 1/2 =
= 8 1/2
It's the same, so it must be correct ;)
Answer: Carly needs 2 cups of flour for each cake.
