Carmel would need 7 gas tanks. (2,240 ÷ 320 = 7)
Carmel would need $273 because since she needs $39 dollars for one gas tank, you would have to multiply that by 7. (39 x 7 = $273)

Answer:

To drive 2,240 miles, Carmel will need 7 tanks of gas. As each tankful costs $39, 7 tanks of gas will cost $273

Step-by-step explanation:

Carmel can drive 320 miles on tank of gas, and one tankful costs $39. In order to know how many tanks of gas will she need to drive 2,240 miles and how much will it cost, we have to do the following calculation:

2240 (total miles) / 320 (miles on tank of gas) = X (how many tanks of gas will she need)

2,240 / 320 = X = 7

To drive 2,240 miles, Carmel will need 7 tanks of gas. As each tankful costs $39, 7 tanks of gas will cost $273 (as 39 x 7 = 273).

What is the solution to the inequality -6+|2p+3|>7
andrezito [222]

Answer:

p >5                  or                            p <-8

Step-by-step explanation:

-6+|2p+3|>7

Add 6 to each side

-6+6+|2p+3|>7+6

|2p+3|>13

We get a positive and negative solution

2p +3 > 13             and  2p +3 < -13

Subtract 3 from each side

2p +3 -3> 13-3           or 2p +3-3 < -13-3

2p > 10                                      2p < -16

Divide by 2

2p/2 > 10/2                                2p/2 <-16/2

p >5                  or                            p <-8

7. Solve the formula M=2P+3Q for the variable Q.
vichka [17]
The answer is <span>Q=(M−2P)/3
</span>
<span>M = 2P + 3Q

Subtract 2P from both sides:
M - 2P = 2P + 3Q - 2P
M - 2P = 3Q

Divide both sides by 3:
(M - 2P)/3 = 3Q/3
(M - 2P)/3 = Q</span>

0.33333333333333333333333333333333333333333333333 simplified at a fraction
USPshnik [31]

Answer:

\frac{1}{3}

Step-by-step explanation:

Your original number to convert is 0.333333. Let's slide the decimal point in this number to the right 1 place(s) (the same number of digits in the number 3).

If we do this, we'll get a 3.333333 (slide the decimal in the 0.333333 right 1 places, you'll get 3.333333).

So what? Well now, we have two numbers with the same repeating decimal parts, 3.333333 and 0.333333.

Now let's just work a little algebra into all of this. Let's call your original number x. And in this case, x = 0.333333. The number with the decimal point slid over can be called 10x, because 10x = 3.333333

10x = 3.33333

-x = 0.333333\frac{10x = 3.33333  -x = 0.333333}{9x = 3}

---------------------------------------------------------------------------------------------

Now, solving 9x=3 for x by dividing both sides of it by 9, we'll get that x=3/9. And this is your answer.

How is this your answer? Well remember that above, x was originally set equal to 0.333333 via x = 0.333333, and now we have that x is also equal to 3/9, so that means 0.333333 = 3/9..and there's 0.333333 written as a fraction.

-------------------------------------------------------------------------------------------

<u>Simplify 3/9 into the lowest terms:</u>
