How many solutions does -2z+2+4z=16/5+2z-6/5
kipiarov [429]

Answer:

Infinite. Please Mark Brainliest, this took a lot of effort.

Step-by-step explanation:

After going through the process of solving, you get 0=0, meaning true for all z

-2z+2+4z=16/5+2z-6/5

Group Like Terms

-2z+4z+2=16/5+2z-6/5

Add similar terms

2z+2=16/5+2z-6/5

Group Like Terms

2z+2=2z-6/5+16/5

<em>Combine the Fractions</em>

Apply the rule a/c plus or minus b over c equals a plus or minus b over c

=(-6+16)/5

Add/Subtract the numbers

=10/5

Divide the numbers

=2

2z+2=2z+2

Subtract 2 from each side

2z+2-2=2z+2-2

Simplify

2z=2z

Subtract 2z from each side

2z-2z=2z-2z

Simplify

0=0

Both sides are equal, true for all z

Find the value of x that makes m||n
beks73 [17]

Answer:

x = 6

Step-by-step explanation:

In order for m to be parallel to n 16x - 6 would have to equal 90. We can demonstrate that using an equation.

16x - 6 = 90

Let's solve for x:

First add 6 to both sides to isolate the 16x:

16x - 6 + 6 = 90 + 6

16x = 96

Now divide both sides by 16 to isolate the x:

16x/16 = 96/16

x = 6

The value of x has to be 6 in order for m to be parallel to n.

The speed of a passenger is 20 mph faster than the speed of a freight train. The passenger train travels 290 miles in the same t
Bond [772]

Answer:

passenger train is travelling 58mph

freight train at 38 mph

Step-by-step explanation:

first i listed all the numbers that could divide 190

1,2,5,10,19,38

& then it was simple from there .

next all i had to do is add 20 to each number and then see if that number could divide 290

38 could divide 190

38+20 =58

290÷58=5

190 ÷38=5

it took the passenger train 5 mins to travel 290 miles while the freight train took 5 mins to trvel 190 miles

32% is the same as 79 million tons. What is total
Gre4nikov [31]

Answer:

225 tons is the total

Step-by-step explanation:

Let the total amount be x

Given that,

32% of x = 72tons

32x/100 = 72tons

32x = 7200tons

x = 225 tons

To verify,

32% of 225 = 72tons

32/100 * 225 = 72 tons

72 = 72

Hence, verified.
