<span>So, the formula for this problem is 10/x =40/64. You can solve for x by cross multiplication so, you end up with 40x=640 with x=16. So Justin should charge his friend $16.00.</span>
Answer:
y= 21/2(3)
Step-by-step explanation: Use exact numbers.
y = ___
I graphed it. First you choose a number that’s less than 29 and greater than 29 which I chose 0 and 100 but it didn’t let me show the whole picture
The first thing we need to distinguish is what 1 and 3/4 means. So, 3/4 = .75, so 1 and 3/4 = 1.75
So, we need 1.75 cups of flour for one batch, since you're making three batches, you need three times as much, so
1.75 * 3
5.25 is the answer, to put it back in to fractions,
5 and 1/4 cups of flour are needed.
Answer:
Explanation:
<em>The line y = -1 </em>is horizontal: parallel to the y-axis.
The point<em> B (2,3)</em> is above <em>the line y = - 1 </em>at a distance equal to the y-coordinate of B (y = 3) less - 1:
When the <em>point B (2,3) </em>is <em>reflected over the line y = -1</em>, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence,<em> the coordinates of the vertex B'</em> are x = 2, y = - 5: (2, - 5).
