The numerator and denominator of a fraction are in the ratio of 2 to 5. If the numerator and denominator are both
decreased by 2, the fraction is now equal to 1.
If n = the numerator and d = the denominator, which of the following systems of equations could be used to solve the problem?

•5n = 2d and n - 2 = 2d-4
•5n = 2d and 2n- 4 = d-2
•2n = 5d and 2n- 4 = d-2
• 2n = 5d and n - 2 = 2d-4

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

step-by-step explanation:

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
