Answer:

-13 13/35

Step-by-step explanation:

5 4/7 * - 2 2/5

Change to improper fractions

5 4/7 = (7*5 +4) /7 = 39/7

2 2/5 = (5*2+2)/5 = 12/5

39/7 * -12/5 = -468/35

Change back to a mixed number

35 goes into 468 13 times with 13 left over

-13 13/35

Shandra drove 220 miles in 5 hours. if she continued at the same rate, how long would it take to travel 352 miles?

NeTakaya

Answer:

8 Hours

Step-by-step explanation:

We know she travels 220 miles in 5 hours, so lets create an equation with a ratio which finds the miles she drives in a single hour, multiply that by x, and then set it equal to 352.

$\frac{220}{5}x=352$

Multiply both sides by 5

$220x=1760$

Divide both sides by 220

$x=8$

Therefore it would take 8 hours.

b. 0.1

Step-by-step explanation:

a. The t-shirts comes in 5 sizes (Small,medium,large, extra large and extra extra large) and two colors orange and black. The total different type of shirts are 5*2=10 different type of t-shirts.Also if we make sample space of all shirts we can assess the total different type of t-shirts. sample space=S={small orange,medium orange,large orange,XL orange,XXL orange,small black,medium black,large black,XL black,XXL black}. n(S)=total different type of shirts=10.

b. P( large orange t-shirt)=n(large orange t-shirt)/n(S)=1/10=0.10.

Which equation can pair with x-y=-2 to create a consistent and dependent system?

MrRissso [65]

See the explanation

<h2>Explanation:</h2>

A system that has one or infinitely many solutions is called <em>consistent. </em>If an equation in a system tells us no new information then the equations of the system are <em>dependent. </em>In other words, to find an equation that creates a consistent and dependent system with the given equation we have to get the same line:

The given line is:

$x-y=-2$

If we multiply both sides of the equation by a constant we will have the same line when plotting, therefore let's multiply by 3:

$3(x-y)=3(-2) \\ \\ 3x-3y=-6$

So a system of two linear equation that is consistent and dependent is:

$\left \{ {{x-y=-2} \atop {3x-3y=-6}} \right.$
