In a - 3 = 15, the value of a HAS to be 18.
In a - 3 is greater than or equal to 15, the value of a is any value that is 18 or higher.
Take the first bracket and it's multiplication, 3(2a+5)
You expand my multiplying everything inside the bracket by the number outside.
3*2a = 6a
3*5 = 15
Then multiply out the second bracket, 5(a-2)
5*a = 5a
5*-2 = -10
So now you have 6a + 15 + 5a - 10
Simplify it by collecting like terms, and you have:
11a + 5
And that's the answer, hope I helped!
The partial product of 4.6×3.5 is 16.1.
Your answer is (3,1) because if you graph the line that is the on off the line the other follow through
