Answer:
6.25
Step-by-step explanation:
f(x)=x^2
f(2.5) = (2.5)^2
=6.25
Answer:
1 . X=-6
2. -9b+6z-2
3. -6z+1
Step-by-step explanation:
1. Solve for x by simplifying both sides of the equation, then isolating the variable.
2. Combine like terms = combine -4b and -5b , combine 5z and z and then -2 is left alone
3. Subtract the numbers
12-11 = 1
Then combine like terms
-15z+9z = -6z
Answer:
12
step by step equation:
Lindsay owns 12 books.
Step-by-step explanation:
We can solve this question using a system of equations.
I am going to say that:
x is the number of books that Lindsay owns.
y is the nuber of books that Destiny owns.
z is the number of books that Henry owns.
Lindsay owns one-third the number of books that Destiny owns.
This means that:
, or
Henry owns a fourth as many books as Destiny.
This means that , or . Also, in function of x, we may have
Together they own 57 books.
This means that
We want to find x. So
Lindsay owns 12 books.
I find it easier to put them in decimal form then to try and find a common denominator
2/3 = 0.666
2/9 = 0.222
5/6 = 0.833
11/18 = 0.611
least to greatest = 2/9, 11/18, 2/3, 5/6
It would be b. the first ratio is
1kL

1000
so you would match up the kL and not know how many regular liters there are.
8kL
