Answer:

8 days

Step-by-step explanation:

We are told in the question:

Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.

How many days will his fuel last?

1/10 of fuel = 1 day

4/5 of fuel = x

Cross Multiply

1/10 × x = 4/5 × 1

x = 4/5 / 1/10

x = 4/5 ÷ 1/10

x = 4/5 × 10/1

x = 8 days

His fuel lasts for 8 days

oksian1 [2.3K]

Answer: Undefined

Step-by-step explanation:

In geometry there are three  undefined terms that we use to define other terms:

  • Point → In geometry a point has a location but no dimension.
  • Plane →  A plane extends is a 2-dimensional surface that extends infinitely on both sides.
  • Line → A line is a one-dimensional undefined figure that extends infinitely in both the directions. It has length but has no width.

Hence, the correct option is "Undefined".

3x-7=4x+10 <br> show the steps pleeease
Fudgin [204]

Answer:

-17

Step-by-step explanation:

3x-7=4x+10

Add 7 to both sides & simplify

3x-7=4x+10

+7           +7

3x=4x+17

Subtract 4x from both sides & simplify

3x=4x+17

-4x  -4x

-x=17

*Negative x equals -1*

Divide both sides by -1 & simplify

\frac{-x}{-1} =\frac{-17}{-1}

x=-17

Lance says that you can compare any decimal numbers the way that you alphatbetize words you can tell which number is first by co
Afina-wow [57]

Answer:

No, Lance's thinking is wrong because you cannot compare decimal numbers with alphabetizing words. For example, if we compare 37.6 to 7.42 using the method of Lance, we would probably say 37.6 is less than 7.42 because 3 is less than 7. But it is wrong. The 3 in 37.6 is in the tens place. On the other hand, 7.42 contains no tense. Therefore, 37.6 is actually higher.
