Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
Answer:
9/34
Step-by-step explanation:
3/4 times 2 5/6
3/4 times 17/6
switch the denominator and numerator then, multiply.
They are all integers so...
first lets substitute
A.3x=13
X=13/3
b.3x+2=13
3x=11
x=11/3
c.3x+4=13
3x=9
x=3
d.3x+6=13
3x=7
x=7/3
E.3x+8=13
3x=5
x=5/3
therefore the possible is letter c because it must be an integer and the definition of integer states that it is not a decimal nor a fraction
Six million, seven thousand two hundred
Since the triangles are similar, then 32 = x+7 those two angles are too
solve for "x"
now using proportions
![\bf \cfrac{\textit{small triangle}}{\textit{large triangle}}\qquad \cfrac{JK}{18}=\cfrac{12}{12+10}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B%5Ctextit%7Bsmall%20triangle%7D%7D%7B%5Ctextit%7Blarge%20triangle%7D%7D%5Cqquad%20%5Ccfrac%7BJK%7D%7B18%7D%3D%5Ccfrac%7B12%7D%7B12%2B10%7D)
solve for JK
![\bf \cfrac{\textit{small triangle}}{\textit{large triangle}}\qquad \cfrac{12}{12+10}=\cfrac{9}{9+KG}\implies 12(9+KG)=(22)9 \\\\\\ 108+9KG=198](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B%5Ctextit%7Bsmall%20triangle%7D%7D%7B%5Ctextit%7Blarge%20triangle%7D%7D%5Cqquad%20%5Ccfrac%7B12%7D%7B12%2B10%7D%3D%5Ccfrac%7B9%7D%7B9%2BKG%7D%5Cimplies%2012%289%2BKG%29%3D%2822%299%0A%5C%5C%5C%5C%5C%5C%0A108%2B9KG%3D198)
solve for KG
the scale factor of the perimeter of both triangles is just the same as the ratio of the sides, or
