<h3><u>The first number, x, is equal to 33.</u></h3><h3><u>The second number, y, is equal to 23.</u></h3><h3><u>The third number, z, is equal to 46.</u></h3>

x + y + z = 102

z = 2y

x = 10 + y

Because we have values of x and z, we can plug them into the original equation to solve for y.

10 + y + y + 2y = 102

Combine like terms.

4y + 10 = 102

Subtract 10 from both sides.

4y = 92

Divide both sides by 4.

y = 23

Now that we have a value for y, we can find the value of x and z.

z = 2(23)

z = 46

x = 10 + 23

x = 33

molly ran 1/4 of a mile in 1 minute if molly runs at that speed how long will it take her to run 4 miles
Vika [28.1K]

Step-by-step explanation:

Molly ran 1/4 of a mile in 1 minute, i.e.

1/4 mile : 1 minute

Multiply both sides by 4 to get time for one mile

1 mile : 4 minutes

Multiply by 4 again to get time for 4 miles

4 miles = 4*4 = 16 minutes.

So it takes Molly 16 minutes to run four miles.
