Answer 1

Вот))) если будут вопросы обращайся)

Answer 2

1) 954-78-a=277
a=954-78-277
a=599
2) 305+x+55=1000
x=1000-305-55
x=640
3) 9*2*c=360
18*c=360
c=360:18
c=20
4) 120:a=48:24
120:a=2
a=120:2
a=60
5) 740+y=1000-50
740+y=950
y=950-740
y=210

Answer 3

Let's solve each equation one by one:

1. 954-78-a=277

To solve for "a", we need to isolate it on one side of the equation. We can start by subtracting 876 from both sides:

954 - 78 - a - 876 = 277 - 876

Simplifying the left side:

0 - a = -599

Finally, solving for "a" by multiplying both sides by -1:

a = 599

Therefore, the solution to this equation is a = 599.

2. 305+x+55=1000

To solve for "x", we need to isolate it on one side of the equation. We can start by combining the constant terms on the left side:

360 + x = 1000

Next, we can solve for "x" by subtracting 360 from both sides:

x = 1000 - 360

Simplifying the right side:

x = 640

Therefore, the solution to this equation is x = 640.

3. 9×2×c=360

To solve for "c", we can divide both sides by 18:

(9 × 2 × c) ÷ 18 = 360 ÷ 18

Simplifying the left side:

c = 20

Therefore, the solution to this equation is c = 20.

4. 120÷a=48÷24

To solve for "a", we can start by simplifying both sides of the equation:

5 = 2

Since this is a false statement, there is no solution to this equation.

5. 740+y=1000-50

To solve for "y", we can start by simplifying the right side:

740 + y = 950

Next, we can solve for "y" by subtracting 740 from both sides:

y = 950 - 740

Simplifying the right side:

y = 210

Therefore, the solution to this equation is y = 210.
