It is 42 1/2 miles from Eaton to Baxter, and 37 4/5 miles from Baxter to Wellington. How far is it from Eaton to Wellington, if

IgorC [24]

$42 \frac{1}{2} + 37 \frac{4}{5}$

$42 \frac{5}{10} + 37 \frac{8}{10}$

$\frac{5}{10} + \frac{8}{10} = \frac{13}{10} = 1 \frac{3}{10}$

$79 + 1 \frac{3}{10} = 80 \frac{3}{10}$

$80 \frac{3}{10} \: \:miles \: or \: 80.3 \: miles$

Just double check that I did the right calculations

The sum of two numbers is 66. two times the smaller number is 15 more then th larger number what are the numbers

Delicious77 [7]

Let x = big number

Let y = small number

x + y = 66...Equation A

2y = x + 15...Equation B

We have two equations in two unknowns.

x + x + 15 = 66

2x = 66 - 15

2x = 54

x = 54/2

x = 27

Plug x = 27 into EITHER equation above to find y.

I will use Equation A.

x + y = 66

27 + y = 66

y = 66 - 27

y = 39

The two numbers are 27 and 39.
