The ratio is 6w = 4f.
Multiply both sides by 3/2 to get 6 cups of flour, and we have:
6*3/2 w = 4 * 3/2 f
18/2 w = 12/2 f
9 w = 6 f
So 9 cups of water.
So I will choose to cancel the y first because that is easiest. To do this, add both equations together.
x+y = -3
+
x - y = 13
This will give us:
2x = 10
therefore, x = 5
Now, we can plug this into the first equation to find y
5+y = -3
y = -3 - 5
y = -8
Answer:
x = 5
y = -8
Hope this helped!! :D
Answer:
Step-by-step explanation:
The correct answer is the second one because these two triangles are congruents And they have the angle s as opposite to right angle.
I hope to help you
<span>Generally according to mathematical formulas the standard deviation is defined as the square root of the variance.Same formula applied to this question where variance is 100 which results that standard deviation is 10.Whereas variance is the square of the standard deviation which is 100 derived in the question.</span>
"<span>Solve Z squared 2 = 1" sounds strange. Do you mean "z squared," or do you mean "Z^2?"
Z^2 = 1 can be solved by finding the sqrt of both sides: Z = plus or minus 1.</span>
