Mathematics
1 answer:
fredd [130]2 years ago
8 0

Answer:

Step-by-step explanation:

Let the ratios be 2x and 7x respectively.  

Now,

2x + 7x = 18

= 9x = 18

= x = 18/9

= x = 2

Hence, 2x = 2*2 = 4

And, 7x = 7*2 = 14

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
34kurt

Answer:

  • Infinitely many solutions

Step-by-step explanation:

First, let's organize the equations of the lines into slope-intercept form.

  • x + 4y = 1
  • => 4y = -x + 1
  • => y = -x/4 + 1/4

And,

  • 2x + 8y = 2
  • => 8y = -2x + 2
  • => y = -2x/8 + 2/8
  • => y = -x/4 + 1/4

Since both the graphs are the same, the two equations have infinitely many solutions.

Perform the following operation
Cerrena [4.2K]

Answer:

When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.

First, multiply normally.

25x10x5

1100

Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.

So, the answer is -1100.
