If 5 potatoes together have a mass of 1 kilometer and 8 pears together have a mass of 1,200 grams, which has the greater mass a potato or a pear? explain.

The Potato has a greater mass.

Step-by-step explanation:

In order to see which one of them has the greater mass, we're going to need to figure out how much one of them weigh.

Lets get the key information from the question:

5 potatoes = 1 kilograms (kg)

8 pears = 1,200 grams (g)

With the information above, we can solve the problem.

1 Kilogram = 1000 grams

With that information, we know that 5 potatoes would equal 1000 grams, now we would need to divide 1000 by 5 to get the grams for one potato in order to find the mass of it.

1 Potato = 200 grams

Now, we would need to divide 1,200 by 8 to find the mass of 1 pear.

1 Pear = 150 grams

With the information we have now, we would know that the Potato has the greater mass than the pear.

A potato has a greater mass.

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.
