12z - 3 ≥ 2z - 15
When you have to solve an equality like that, you need to put the variables apart (the numbers with letters) and the numbers apart.
So first, we need to reunite the variables, by subtracting "2z" from both sides of the equation:
12z - 3 ≥ 2z -15
12z - 2z - 3 ≥ 2z - 2z - 15
12z - 2z - 3 ≥ -15
10z - 3 ≥ 15
Then we add 3 to both sides:
10z - 3 + 3 ≥ -15 + 3
10z ≥ -12
Now divide both sides by 10
(10z)/10 ≥ -12/10
z ≥ -6/5
Now we need to write the answer as a mixed number.
-6/5 = -1.2
0.2 = 1/5
9
So -6/5 = -1 1/5.
So 12z - 3 ≥ 2z - 15 for Z ≥ -1 1/5
Hope this helps! :)
1 min = 60 seconds
15 miles/sec * 1/60 = 0.25 miles/min
If 0.25 miles in 1 min,
then:
0.25 * 4 mins = 1 mile.
(I hope this is correct)
Answer:
16
Step-by-step explanation:
b x h is finding a square or rectangle, but since a triangle is half of a rectangle or square you can divide that by 2. So, 8 (b) x 4 (h) = 32, 32 / 2 = 16. Hope this helps! :D
