z/4 + 5 >= 5.5
-5 -5 subtract 5 from both sides
z/4 >= 0.5
x4 x4 times both sides by 4
z >= 2.0
Start by converting to like terms, so convert 1/2 to 2/4.
Next, look at the problem. You are adding a negative, which is the same as subtracting, so your new problem looks like this: 2/4 - 3/4.
If you take 3/4 from 2/4, you are left with -1/4. This is your final answer!
Answer:
1. y=kx
2. y=60
Step-by-step explanation:
y is directly proportional to x
y=kx
Find Constant K, when y=30 & x=6
Make K the subject of the formula first
K=y/x
K=30/6
k=5
When k is 5, x is 12, find y
y=kx
y=5×12
y=60
