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
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.
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
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.
