If A varies directly with z, and A is 30 and z is 5, then when z is 1, A is 6.
z: 5 ÷ 5 = 1
A: 30 ÷ 5 = 6
Then, when z is 1, A is 6
So, when z is 9, A is...
z: 1 × 9 = 9
A: 6 × 9 = 54
A is 54
Answer:
Step-by-step explanation:
The solution to a system of linear equations is the ordered pair (or pairs) that satisfies all ... Solve the following system of equations by substitution. ... For example, consider the system of equations below: 3x + 2y = 6 x − y = 8 ... 12x + 18y = 39
If written out it will look like this 1 + 4 * x
Answer:
1/27
Step-by-step explanation:
Ok this looks like a huge number but if you break it into smaller numbers its easier to work with
3^5=243 so we can write...
(3^5)^-3/5
Rule of exponents state that you can multiply powers
5*3/5=15/5=-3
Because its negative we would make it over 1
1/3^3
And simplify...
1/3*3*3
1/27
