Answers

Answer 1
Answer: There are 5 boxes, where we have to put given numbers. Addition of 5 odd numbers always gives an odd number result. 30 is an even number. So there is no combination of given numbers which can give you 30 as a result.

Hello,

a-3b=4 (1)
a-b=-2 (2)

(1)-(2)==> -2b=6
=>b=-3 and a=-2+(-3)=-5

A system of equations is shown below: 6x - 5y = 5, 3x + 5y = 4. The x-coordinate of the solution to this system of equation is what?Thank you to however can help me with this. I've been having a lot of trouble with this math concept. :)

Answers

6x - 5y = 5
3x + 5y = 4

If the left sides are equal to the right sides then if we add left side of first equation to left side of the second one and right side of the first euation to right side of the second  one they still would be equal


             6x - 5y = 5
             3x + 5y = 4
             9x +0y = 9
               9x = 9
                 x = 1

Divide 85 into the ratio of 2:3:5

Answers

The actual amount that needs to be divided = 85
The ratio in which the amount needs to be divided = 2:3:5
Let us assume the common ratio to be = x
Then
2x + 3x + 5x = 85
10x = 85
x = 85/10
  = 8.5
Then
The ratio in which the number 85 will be divided = 2 * 8.5:3 * 8.5:5 * 8.5
                                                                             = 17:25.5:42.5
So from the above deduction we can see that the number 85 can be divided in the ratio 17:25.5:42.5
