Question

X×X-24=8×5. 3×y-8=25 . 48:a=2×2×2×2

Answer 1

Ответ:

Пошаговое объяснение:

x^2-24 = 40

x^2 = 64

x = +-8

3y-8 = 25

3y = 33

y = 11

48:a = 16

16a = 48

a = 3

Answer 2

It looks like you've provided a set of equations and an expression. Let's break down each part:

1. Equation 1: $X \times X - 24 = 8 \times 5$

   This equation is a quadratic equation. To solve for $X$, follow these steps:

   $X^2 - 24 = 40$ $X^2 = 64$ $X = \pm 8$

   So, $X$ can be either 8 or -8.

2. Equation 2: $3 \times y - 8 = 25$

   To solve for $y$, follow these steps:

   $3y - 8 = 25$ $3y = 33$ $y = 11$

3. Expression: $48 : a = 2 \times 2 \times 2 \times 2$

   This expression represents a division. To find the value of $a$, follow these steps:

   $48 : a = 2 \times 2 \times 2 \times 2$ $48 = 16a$ $a = \frac{48}{16}$ $a = 3$

So, the solutions are:

• For Equation 1: $X$ can be either 8 or -8.
• For Equation 2: $y = 11$.
• For the expression: $a = 3$.
