Question

A) 15x = 0,15; 6) 3,08 : y = 4;B) 3a + 8a = 1,87;r) 72 - 32 = 5,12;A) 2t + 5t + 3,18 = 25,3;​

Answer 1

А) x = 0,15:15
x=0.01
b) 3,08:y=4
y=0,77
c) 3a+8a=1,87
11a=1,87
a=0,17

Answer 2

Пошаговое объяснение:

15х=0,15

15х-0,15=0

1500х=0

Answer 3

It seems like you have a set of equations and you want to solve for the variables in each equation. Let's solve each equation step by step:

A) 15x = 0.15:

To solve for x, divide both sides by 15: x = 0.15 / 15 x = 0.01

6. 3.08 ÷ y = 4:

To solve for y, divide both sides by 4: 3.08 ÷ 4 = y y = 0.77

B) 3a + 8a = 1.87:

Combine like terms on the left side: 11a = 1.87

Now, solve for a by dividing both sides by 11: a = 1.87 / 11 a ≈ 0.17 (rounded to two decimal places)

R) 72 - 32 = 5.12:

Subtract 32 from 72: 72 - 32 = 40

A) 2t + 5t + 3.18 = 25.3:

Combine like terms on the left side: 7t + 3.18 = 25.3

Subtract 3.18 from both sides: 7t = 25.3 - 3.18 7t = 22.12

Now, solve for t by dividing both sides by 7: t = 22.12 / 7 t ≈ 3.16 (rounded to two decimal places)
