Mathematics
1 answer:
Vilka [71]3 years ago

We have the system of equations:

3x + 5y = 10

x + 5y = 2 => x = 2 - 5y

__________________

3*(2 - 5y) + 5y = 10

6 - 15y + 5y = 10

-4 = 10y

y = -4/10 = -2/5 => x = 2 - 5*y = 2 - 5*(-2/5) = 2 + 2 = 4

The correct answer is x = 4.

I need help ASAP PLEASEEEEEEEEEEEEEEEEEE
Oksanka [162]

Answer:

97,99,101,103

Step-by-step explanation:

Let x = first odd integer

x+2 = 2nd odd integer

x+4 = 3rd odd integer

x+6 = 4th odd integer

Sum of 4 odd integers is 400

x+ (x+2) + (x+4)+(x+6) = 400

Combine like terms

4x +12 = 400

Subtract 12 from each side

4x+12-12 = 400-12

4x = 388

Divide by 4 on each side

4x/4 = 388/4

x=97

The first integer is 97

The 2nd is 97+2 =99

The third ix 97+4 = 101

The 4th is 97+6 = 103
