Answer:
a) y = 5x
b) y = 60
Step-by-step explanation:
Since, y is directly proportional to x when y=30, x=6
.66 is 66 out of 100. "out of" means divide
66/100
We can reduce this by dividing each number by the same amount - 2
33/50
150 - s <== ur expression
when s = 27.13
150 - 27.13 = 122.87
when s = 55.14
150 - 55.14 = 94.86
If you would like to solve the equation x^2 + 12 * x = -11, you can calculate this using the following steps:
x^2 + 12 * x = -11
<span>x^2 + 12 * x + 11 = 0
</span>(x + 1) * (x + 11) = 0
1. x = - 1
2. x = - 11
The correct result would be x = - 1, or x = - 11.
