In my opinion I think that you have to multiply 13.55 by 8 ounces to find how much she needs to pay.
Answer:
The vertex form of the equation is
.
Step-by-step explanation:
You will use the equation
to solve this parabola. (h, k) is the vertex. So, we plug this into the equation to get
.
Then, we substitute the point as our x and y to get
(a lot of simplifying was done here). Then, add 2 to the right side of the equation and isolate the
to get
. Finally, divide by 9 on both sides to get
.
Now, substitute your
back into the equation to get y =
.
This is in vertex form. If the answer is needed in standard form, simply distribute and simplify to get
.
Lets write an equation for each guy's shots and score:
4A + 2B = 18
3A + 3B = 21
To solve we multiply the first equation by -3 and the second by 2:
-12A - 6B = -54
6A + 6B = 42
--------------------
-12A + 0 = -12
A = 1
to find B we substitute in the first equation:
<span>4A + 2B = 18
</span><span>4(1) + 2B = 18
</span><span>4 + 2B = 18
</span>2B = 14
B = 7
therefore there were given 7 points in an arrow in B
Rounding depending on what the problem is
Answer:
The answer is 10/36 or if you want to simplify, 5/18
Step-by-step explanation:
To solve the area of a rectangle, you need to multiply the sides with each other, so 5/12 x 2/3 is 10/36 (unsimplified) . You multiply the numerators and then the denominators and simplify.
