This can be solved by ratio and proportion. The first condition is
3 1/2 hours is to 1/3 tank of gas

The proportion relation is
3 1/2 : 1/3 :: x : 1/2

where x is the number of hours that Tanya can drive
7/2 / (1/3) = x / (1/2)
Solving for x
7/6 = x/2
x = 14/6 or 2 and 1/3 hours<span />

I WILL GIVE BRAINLIEST<br> Solve the equation:<br> x/−4 + 6 = −6.5
konstantin123 [22]

Answer:

x = 50

Step-by-step explanation:

<em><u>The first step is to subtract 6 from both sides:</u></em>

Is 369/100 greater than 849/100
deff fn [24]

9514 1404 393

Answer:

  no

Step-by-step explanation:

When fractions have the same denominator, you can compare the numerators.

  369 < 849

369/100 is not greater than 849/100

__

Here, you can convert these to decimal numbers and do the comparison in the usual way:

  3.69 < 8.49

The most-significant digits are in the same number place (units), and they are different. The number with the smaller most-significant digit is smaller.
