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.
