Hello there,

How do i substitute y=x to 3x+2y=20

Answer : since both are equal , you can change the letters to the same one.
3x + 2x = 20
5x = 20
x = 5
Therefore y = 5

Hope This Helps You!
Good Luck Studying :)

Five bags of dog food costs $21.25.

Step-by-step explanation:

We can solve using proportions.

$\frac{6 \: bags}{25.50 \: dollars} = \frac{5 \: bags}{x} \\ \\ \frac{127.5}{6} = \frac{6x}{6} \\ \\ 21.25 = x \\ 21.25 \: dollars = x$

Question 1 of 10 Jerry drew AJKL and AMNP so that K = ZN, ZLE ZP, JK = 6, and MN = 18. Are AJKL and AMNP similar? If so, identif

butalik [34]

Answer:

This is the answer I got

Step-by-step explanation:

JK / KL = MN / NP 6 / 4 = 18 / 12

Now u cross multiply. if both numbers are equal, they are similar. In this case, they are similar. 6 x 12 = 4 x 18

72 = 72

though the two corresponding sides of the triangles mentioned are proportional (proportionality being 1:3 ) but they need not be similar

for similarity either the third corresponding sides must be proportional or the included angle between the two proportional sides must be equal
