32 miles is the same as 19.8839 kilometers

There are 3.78541 liters in a gallon

Now we divide the two. 

19.8839 / 3.78541 ≈ 5.25

The American car gets 5.25 km per liter. So the European car is better on gas economy.

Find the distance between (-3, -4) and (2, -4)
Sergeu [11.5K]

Answer:

  • \boxed{\sf{5}}

Step-by-step explanation:

Distance can be calculated using a distance formula.

<h3>⇒ (-3,-4) and (2,-4)</h3>

<u>Distance formula:</u>

\Longrightarrow: \sf{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} }

<u>The distance between (-3,-4) and (2,-4) are:</u>

\Longrightarrow: \sf{\sqrt{\left(2-\left(-3\right)\right)^2+\left(-4-\left(-4\right)\right)^2}}

<u>Then, you solve.</u>

\Longrightarrow:\sqrt{\left(2-\left(-3\right)\right)^2+\left(-4-\left(-4\right)\right)^2}=\boxed{\sf{5}}

  • <u>Therefore, the distance between (-3,-4) and (2,-4) is 5, which is our answer.</u>

I hope this helps you! Let me know if my answer is wrong or not.

What is the value of x that will make each of the two ratios proportional?
PilotLPTM [1.2K]

Answer:

a=7, b=14

Step-by-step explanation:

a. 2/6=x/21

cross multiply=

2×21=x×6

then solve

42=6x

divide both sides by 6

x=42/6=<u>7</u>

b. 150/84=25/x

cross multiply=

84×25=150×x

then solve

2100=150x

divide both sides by 150

x=2100/150=<u>1</u><u>4</u>

<u> </u><u> </u><u> </u><u> </u><u>H</u><u>O</u><u>P</u><u>E</u><u> </u><u>T</u><u>H</u><u>I</u><u>S</u><u> </u><u>H</u><u>E</u><u>L</u><u>P</u><u>S</u><u>.</u><u> </u><u> </u><u> </u>

Esme says the two expressions 4x - 5.2y + 6y + 7.9x - 8x and 19.9x + 11.2y are equivalent. Is she correct? Explain how you know.
Ipatiy [6.2K]

Answer:

No, she's incorrect. 4x - 5.2y + 6y + 7.9x - 8x = 3.9x + 0.8y

Step-by-step explanation:

To find out if Esme is correct, we have to group the like terms and simplify.

  • (4x+7.9x-8x) + (-5.2y+6y)
  • 3.9x+0.8y

As you can see, 3.9x + 0.8y is the correct simplified expression, thus making Esme incorrect.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
