Answer:
Step-by-step explanation:
let : x and t this numbers : x +y = -81/4
y == -52/3
x + (-52/3) = -81/4
x = -81/4 + 52/3........continue
Answer:
63.5
Step-by-step explanation:
1000× 6.35 / 100 = 63.5
Answer:
About 3.6 times greater.
Step-by-step explanation:
That is 1.793 * 10^8 / 5.01 * 10^7
= 1.793 / 5.01 * 10^(8-7)
= 0.36 * 10
= 3.6
Answer:
x = 4 ±√26
Step-by-step explanation:
Please write this as x^2 - 8x = 10, or x^2 - 8x - 10 = 0. " ^ " indicates exponentiation.
Let's complete the square:
x^2 - 8 x can be rewritten as
x^2 - 8x + 16 - 16, and so
x^2 - 8x = 10 becomes x^2 - 8x + 16 - 16 - 10 = 0, or
(x - 4)^2 = 26
Taking the square root of both sides, we get:
x - 4 = ±√26, or
x = 4 ±√26
