x = 13/8
x = 25/16
x = 7/4
Answer:
x=25/16
Step-by-step explanation:
Approximate Roots of Functions:
We are required to find the root of
Let's construct a function
Reducing:
The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)
We'll move up on x=1.52
We are closer to the solution, let's try some more up
This value x=1.54 is close enough to the solution of the original equation
From the options given, is the closest to our solution
Answer:
it's 27/16
Step-by-step explanation:
got it right on the test
Answer:
x=36
Step-by-step explanation:
1=0.25
x=9
0.25x=9
divide both sides by 0.25
so x=36
a student can buy 36pencils with 9 dollars
Answer:
Step-by-step explanation:
9/0.25=9/1/4=9*4=36
A=p+prt solve for r
Answer:
Step-by-step explanation:
The first step is to take p on both sides:
On the right hand side, cancel p and -p, since . The equation will be:
Then, divide both sides of the equation by p*t:
On the right hand side, p*t can be cancelled:
Answer:
r=A-p (the line is the bar so this is a-p over pt)
pt
Step-by-step explanation:
P+Prt=A
Prt=A−P isolate the term which contains r
Prt=A−P
divide pt by each side
