Answer:
25-7
Step-by-step explanation:
"Substitute for": Replace x with ____
Since it is given that x = 25 -y, we can replace the x in 5x + y = 10 with 25 - y by the substitution property of equality.
When you multiply powers, you add them. You keep the constant (2) the same.
3+18= 21
2^21 <=== the answer
“D” is the answer.

because 1 1/2 * 1 1/2 *1 = 2 1/4
Step-by-step explanation:
A baseball field is in the shape of a square (or diamond). Home plate and second base are opposite corners of each other. So the distance is equal to the diagonal of the square.
Use Pythagorean theorem to find the diagonal, or use properties of a 45-45-90 triangle.
Using Pythagorean theorem:
c² = a² + b²
c² = (90 ft)² + (90 ft)²
c = 90√2 ft
c ≈ 127 ft
