Answer:

check: 50+160+130+20 = 360

50:160 = 5 : 16

Step-by-step explanation:et the smaller of the unknown angles be 5x and the larger of the two be 16x

so 130+20+5x+16x = 360

21x = 210

x = 10

so the two missing angles are 50° and 160°

check: 50+160+130+20 = 360

50:160 = 5 : 16

Aaron and Maria collected shells one morning at the beach. Maria had 3 times as many as Aaron, but they would have had the same
Hoochie [10]
Let the amount of shells collected by Aaron be x and the amount of shells collected by Maria be y respectively. Then the following system of equations should be solved:
\left \{ {{3x=y} \atop {x+8=y-6}} \right.

First of all, express y out of first equation:
y=3x

Then, replace y in second equation with found expression and solve it:
x+8=3x-6
2x=14
x=14/2=7

Finally, replace x in first equation with found value and solve it too:
3*7=y
y=21

So, Aaron has found 7 shells while Maria has found 21.
