Answer:5 and 3
So we let the number take the letter b, anc the expression of the question is:
b^2+15=8×b.....so
b^2+15=8b
Then we take the 8b to the other side of the equal sign so that it becomes...
b^2+15-8b=0
Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...
From there we work out to get two different numbers...either b-5=0
b=5
Or b-3=0
b=3
So the two numbers are 5 and 3
Answer:
-1/2 +or- 1
Step-by-step explanation:
Answer:
I/pr = t
Step-by-step explanation:
It's actually very simple:
~you have to make it into a distributive problem to get t from the other variables.
I= prt
I= t(pr)
Divide both sides by pr
I/pr= t(pr)/pr
I/pr = t
Yes the answer looks unfinished, but that is what literal equations look like in the end.
Make sure that I is capitalized or else you will get it wrong.
