Answer:

120 miles in 2 hours

Step-by-step explanation:

120 because half of a tank is 60 miles so a whole tank means double half, which gives 120 and you also double the hour to 2 hours.

-1 2/3 / (-2 1/5)<br> solve this for me please &&' thank you

dangina [55]

Start by putting into improper fractions.
- 1 2/3 = - 5/3
- 2 1/5 = - 11/5

Now stack the fractions like this.

$\frac{ \frac{-5}{3} }{ \frac{-11}{5} }$

Here's the key part (or one of them). Cancel the minus signs. Since there are 2 of them they become a plus.

$\frac{ \frac{5}{3} } { \frac{11}{5} }$

Now invert the 11/5. That means turn it upside down. Put the 5 in the numerator and 11 in the denominator. Multiply by it by the top fraction.

$\frac{5}{3} * \frac{5}{11}$

When you do this, you just multiply top by top and bottom by bottom

I really need help now

Answer: x=-10

Step-by-step explanation:

Let's solve your equation step-by-step.

6.2x+8=3(1.4x−4)

Step 1: Simplify both sides of the equation.

6.2x+8=3(1.4x−4)

6.2x+8=(3)(1.4x)+(3)(−4)(Distribute)

6.2x+8=4.2x+−12

6.2x+8=4.2x−12

Step 2: Subtract 4.2x from both sides.

6.2x+8−4.2x=4.2x−12−4.2x

2x+8=−12

Step 3: Subtract 8 from both sides.

2x+8−8=−12−8

2x=−20

Step 4: Divide both sides by 2.

2x2=−202

Describe how you would use the distributive property to simplify {39×5}

GuDViN [60]

Have you learnt about prime numbers yet? 5 is a prime number so you can't break it up into smaller numbers other than obviously 5*1. 39 is not a prime number. At first glance you should be able to tell that its a multiple of 3 right?
39=3*13

Now you have smaller numbers.

3*13*5=13*15.

I guess that's what the answer is.

How to solve 2/3(3×+9)=-2(2×+6)

Furkat [3]

2/3 (3x + 9) = -2(2x + 6)

Step by step

2/3 * 3x and 2/3 * 9 = 2x and 6

which is 2x + 6 (since 6 is a positive put a plus 6 [ + 6 ] )

-2 * 2x and -2 * 6 = -4x and -12

which is -4x - 12 (since 12 is negative put a minus 12 [ - 12 ])

We now have 2x + 6 = -4x - 12

now add 4x on both sides

2x + 6 + 4x = −4x − 12 + 4x

6x + 6 = −12

now Subtract 6 from both sides.

6x + 6 − 6 = −12−6

6x=−18

finally Divide both sides by 6.

6x/6 = -18/6

x = -3

The answer is x=−3
