Question

3x+83x+100=960 450÷(4m-m)=3

Answer 1

Ответ:

1.  х=10

2.  m=50

Пошаговое объяснение:

1.  3x+83x+100=960

86х=960-100

86х=860

х=860/86

х=10

Проверим:

3*10+83*10+100=960

30+830+100=960

960=960

2.  450÷(4m-m)=3

450:3m=3

3m=450:3

3m=150

m=150:3

m=50

Проверим:

450:(4*50-50)=3

450:150=3

3=3

Answer 2

To solve the equations:

1. 3x + 8y + 100 = 960

Combining like terms, we have:

6x + 8y = 860

2. 450 ÷ (4m - m) = 3

Simplifying the denominator, we have:

450 ÷ 3m = 3

Now, let's solve each equation separately.

Equation 1: 6x + 8y = 860

Since there are two variables, x and y, we can't find a unique solution without additional information.

Equation 2: 450 ÷ 3m = 3

To solve this equation, we can multiply both sides by 3m:

450 = 3 * 3m

Simplifying:

450 = 9m

Now divide both sides by 9:

m = 450 ÷ 9

m = 50

Therefore, the value of m is 50.
