Answer:

Step-by-step explanation:

14 + 16 = 30

30 + 11 = 41

41 + 2 = 43

43 + 6 = 49

49 + 6 = 55

55 + 15 = 70

70 + 2 = 72

72 + 11 = 83, which, rounded to the nearest tenth, is 80

Answer:

It takes 26 2/3 gallons to make a 400 mile trip.

Step-by-step explanation:

This question is simply asking for the number of miles per gallon . In math, <em>per</em> means this is meant to be written as a fraction.

"If a trip of 270 miles required 18 gallons of gas" is actually saying "270 miles per 18 gallons." This can be written as a fraction like so: 270/18.

If we're looking for the amount of gas used for a 400 mile trip, we have the fraction: 400/g, g being the amount of gallons it took to make that trip.

Now we can set up the proportion: $\frac{270}{18} =\frac{400}{g}$

Cross multiply and solve accordingly.

$\frac{270}{18} =\frac{400}{g}$

400 $270g = 400 *18\\ 270g = 7200\\g=26\frac{2}{3}$ /g

So the answer is:

It takes 26 2/3 gallons to make a 400 mile trip.

Can I have some help?

lisabon 2012 [21]

Answer:

$x = \sqrt{58}$

Step-by-step explanation:

first, you should draw a line to separate the triangle from the rectangle

You can get the height if the triangle by saying 16-9

This will give you 7

The base of the triangle is 3 because the opposite side is given and the opposite sides of a rectangle are equal

Now that we have the measurements of the triangle we can use the Pythagorean theorem

${c}^{2} = {a}^{2} + {b}^{2}$

${x}^{2} = {7}^{2} + {3}^{2}$

${x}^{2} = 49+ 9$

${x}^{2} = 58$

$x = \sqrt{58}$

Gwar [14]

To find the answer, you have to set each one equal to each other.

(160 + 40x = 55x)

Now, you just solve for X.

55x - 40x = 15x

160 / 15 = 15 / 15x

This means 160/15 = x, or is equal to
