Answer:
9k/64^2 (9k^2/64^2)
Step-by-step explanation:
We are required to write an inequality for the expression and also solve it
The number y is at least 10.9
let
the unknown number = y
The sum of a number y and 6.2 = y + 6.2
y + 6.2 ≤ -4.7
y ≤ -4.7 - 6.2
y ≤ 10.9
Therefore,
The expression is represented by the inequality y + 6.2 ≤ -4.7 and y ≤ 10.9

Answer:
The integers are 4 and 7 or -2 and 1.
Step-by-step explanation:
You can make a system of equations with the description of the two integers.
1. x = y + 3
2. 2x + 2 = y^2
The simplest and the fastest way to solve this system in this case is substitution. You can substitute x for y + 3 in the second equation.
1. x = y + 3
2. 2(y + 3) + 2 = y^2
Now simplify and solve the second one. For convenience, I will just disregard the first equation for now.
2y + 6 + 2 = y^2
y^2 - 2y - 8 = 0
You can factor this equation to solve for y.
(y - 4) (y + 2) = 0
y = 4, y = -2
Now we can substitute the value of y for x in the first equation.
x = 7, x = 1
27 times 27
7 times 2,401
1,000,000,000 divided by 10,000,000
390,625 divided by 5
hope this helps!!
