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

Amelie is making a recipe that uses 1 3/4 cups flour. She is making 2 1/2 times the original recipe.
elixir [45]

Answer:

She would need 4\frac{3}{8} flour to make  2\frac{1}{2} times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = 1 \frac{3}{4}\ cups of flour.

So, to make 2\frac{1}{2} times the recipe she would need =1 \frac{3}{4}\times 2\frac{1}{2}.

We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).

=\frac{7}{4}\times \frac{5}{2}

=\frac{35}{8}

Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

\frac{35}{8}=4\frac{3}{8}

So, she would need 4\frac{3}{8} flour to make  2\frac{1}{2} times the recipe.

Write the equation of the line that passes through the points (-9,-4) and (-9,4).
Usimov [2.4K]

Answer:

x = -9

Step-by-step explanation:

x = -9 would be the slope because when you see the two points for each coordinate there is no x value but we do see a straight line and we see that there is no y-intercept. So, x= -9 would be the answer. Hope this helps.
