Step-by-step explanation:
Going to assume you need to know that value of x
2x + 6 = 2
isolate the variable by subtracting 6 on both sides
2x = 8
divide by 2
x = 4
Answer:
19.5 miles per hour
Step-by-step explanation:
We need to change 20 minutes to hours
1 hours = 60 minutes
20 minutes * 1 hour/60 minutes = 1/3 hour
To find miles per hour we take the miles and divide by hours
6.5 miles
---------------- = 19.5 miles per hour
1/3 hours
You're on the right track. Start by combining like terms on the left side of the equation by adding 56 and 34.
90 = n + 30, now subtract 30 from both sides of the equation to isolate the variable n.
60 = n is the answer.

3x + 2y - 4z/x for x=5, y=-2, z=10
3x + 2y - 4z/x
3(5) + 2(-2) - 4(10)/(5)
15 - 4 - 40/5
15 - 4 - 8
11 - 8
