When the smoke cleared, the ratio of believers to skeptics was 15 to 7.If they were 105 believers, how many skeptics were there? PLEASE ANSWER QUICK

Step-by-step explanation:

Belivers to skeptics = 15 : 7

From the above ratio, we know that:

Believers = 15

Skeptics = 7

There were 105 believers, then we can rewrite the original ratio to be equal to the new one, to solve for x.

15 : 7 = 105 : x

Ratios can be written as fractions. Rewrite to simplify.

=

Cross multiply (numerator * denominator = numerator * denominator)

7 * 105 = 15 *x

735 = 15x

Divide both sides of the equation by 15

x = 49

There were 49 skeptics.

Hope this helps! Let me know if you have any questions!

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
