Evaluate using the values given. ZX - [z - (4 + x)/6] when x = 2, z = 6

ICE Princess25 [194]

Answer:

Step-by-step explanation:

First, you should replace the variables with the numbers. So,

2(6)-[6-(4+2)/6]

Don't worry, it'll look less confusing later! Next, solve the parentheses that are in the very middle.

2(6)-[6-6/6]

2(6)-[6-1]

12-5

I really hope this helps you!!! Have an amazing day c:

20 POINTS~ 2/5 |5x+10| -14 > -6 Please explain both answers

Pavlova-9 [17]

Answer:

$x2$

Step-by-step explanation:

We have the inequality:

$\frac{2}{5}|5x+10|-14>-6$

First, we can factor out a 5 from our absolute value. This yields:

$\frac{2}{5}(5|x+2|)-14>-6$

Simplify:

$2|x+2|-14>-6$

Add 14 to both sides:

$2|x+2|>8$

Divide both sides by 2:

$|x+2|>4$

Definition of Absolute Value:

$x+2>4\text{ or } -(x+2)>4$

Solve each case individually:

Case 1:

$x+2>4$

Subtract 2 from both sides:

$x>2$

Case 2:

$-(x+2)>4$

Divide both sides by -1. Flip the sign:

$x+2$

Subtract 2 from both sides:

$x$

So, our answers are:

$x2$

Since our inequality is a greater than, we will have an "or" inequality.

So, our answer is all values left to the first solution and all values to the right of the second solution:

$x2$

And we're done!

A delivery truck drove 203 mi in 3.5 h. After unloading and loading new cargo, it traveled on another 243 mi for 4.5 h. What was

Firdavs [7]

The average speed of the truck is calculated by dividing the total distance traveled in a span of the total time given. From the given above, the total distance traveled is
total distance = 203 mi + 243 mi = 446 mi
and the total time it took for the whole trip is
total time = 3.5 h + 4.5 h = 8 h
The average speed is therefore,
average speed = 446 mi/8 h = 55.75 mi/h
Thus, the answer is letter A.
