To find the percentage of cookies baked by Jenny we first have to know how many cookies total there were. 15+18+17=50 cookies all together. The question is asking us "what percentage" (x) "of" (multiply) 50 "is" (equals) 15? Using the variables and numbers only our questiion becomes 50x = 15. Divide both sides by 50 to get x = .3. Since this value is a percentage, we find that percentage by multiplying by 100. 30%.
Answer:
the answer to the question is -2
Step-by-step explanation:
a certain number=x
therefore,x+9=5-x
x+x=5-9
2x= -4
you the divide both sides by2 to gain x
Answer:

Step-by-step explanation:
The whole triangle and small triangle are similar (AA). Therefore the sides are in proportion:

<em>cross multiply</em>
<em>use distributive property</em>

<em>subtract 220 from both sides</em>
<em>divide both sides by 55</em>

First, we'd need to find the feasible region which is bounded by the constraints 2 ≤ x ≤ 6, 1 ≤ y ≤ 5 and x + y ≤ 8. Let's graph all of them and we'll get the feasible region as unshaded in the attached image. To find the maximum for p = 3x + 2y, we'll plug the coordinates of the vertices in and compare them.
p(6,1) = 3(6) + 2(1) = 20
p(2,1) = 3(2) + 2(1) = 8
p(2,5) = 3(2) + 2(5) = 16
p(3,5) = 3(3) + 2(5) = 19
p(6,2) = 3(6) + 2(2) = 22
So the maximum value of p is 22 as x = 6 and y = 2.
