Apples sell for $1.90 per pound and bananas sell for $0.75 per pound. troy bought some apples and some bananas. together they weighed 3.8 pounds and cost $5.84. how many pounds of apples and how many pounds of bananas did troy buy? 1.9 pounds of apples; 1.9 pounds of bananas 1.2 pounds of apples; 2.6 pound of bananas 2.6 pounds of apples; 1.2 pounds of bananas 1.5 pounds of apples; 2.3 pounds of bananas

1.5 pounds of apples; 2.3 pounds of bananas

Step-by-step explanation:

x=amount of apples bought. (in pounds)

y=amount of bananas boutht (in pounds)

We can suggest this system of equations:

x+y=3.8

1.9x+0.75y=5.84

We can solve this system of euqtions by substitution method.

x+y=3.8        ⇒ y=3.8-x

1.9x+0.75(3.8-x)=5.84

1.9x+2.85-0.75x=5.85

1.15x=5.84-2.85

1.15x=2.99

x=2.99/1.15

x=2.6

y=3.8-x

y=3.8-2.6

y= 1.2

boxplot e is the answer

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
