Question

A) 4*25*x=800 б) y*5*20=500, в) 21×8×p=168 г) m×3×3=990

Answer 1

А) 4•25•х=800
100•х=800
х=800:100
х=8
б) у•5•20=500
у•100=500
у=500:100
у=5
в) 21•8•р=168
168•р=168
р=168:168
р=1
г) м•3•3=990
м•9=990
м=990:9
м=110

Answer 2

А) х=8
б) y=5
в) p=1
г) m=110

Answer 3

To solve each of the equations, we need to isolate the variable on one side of the equation. Here are the solutions for each equation:

A) 4 * 25 * x = 800

Step 1: Divide both sides by (4 * 25) to isolate x. x = 800 / (4 * 25) x = 800 / 100 x = 8

B) y * 5 * 20 = 500

Step 1: Divide both sides by (5 * 20) to isolate y. y = 500 / (5 * 20) y = 500 / 100 y = 5

C) 21 × 8 × p = 168

Step 1: Divide both sides by (21 * 8) to isolate p. p = 168 / (21 * 8) p = 168 / 168 p = 1

D) m × 3 × 3 = 990

Step 1: Divide both sides by (3 * 3) to isolate m. m = 990 / (3 * 3) m = 990 / 9 m = 110

So, the solutions to the equations are: A) x = 8 B) y = 5 C) p = 1 D) m = 110
