This is a simple multiplication, written in a strange form.
5(t+2) means 5 x t + 5 x 2 which simplifies to:
5t + 10
If it's equal to a number, 0 for example, then with a little rearranging we can find what t is.
5t + 10 = 0,
5t = -10
t = -2
If it's not equal to something, the answer is just 5t + 10.
(-5,-3) since plug in a=b-2 into the first equation and then solver for b. You get -3.-3-2=-5 which is a
One of the reasons could be , because he was covering up the negative results and showing only the positive side of it .
Answer: a,c,f (4^3, 8^2, 2^6)
Step-by-step explanation:
He is not correct because when you multiply 30 by 3 1/3 you get 100, 24x 3 1/3= 80, not 70.
Hope this helps :)
