Question

please say the right answer​

Answer 1

Answer:

1) 8

2) 2

3) 7/5

5) 1/2

Step-by-step explanation:

1) cross multiply

= (x-5) * 5 = (x-3) * 3

= 5x - 25 = 3x - 9

= 5x-3x= 25-9

= 2x = 16

= x = 16/2 = 8

2) 3*(3t - 2) - 4*(2t + 3)/12 = 2/3 - t

=(9t-6)-(8t-12)/12 = 2/3-t

=(9t-6)-(8t-12)= 12 (2/3 -t)

=(9t-8t)-18= 24/3- 12t

=t-18= 8-12t

=t+12t = 8+18

=13t= 26

=t=2

3) m - (m - 1)/2 = 1- (m - 2)/3

(2m - m + 1)/2 = (3 - m + 2)/3

(m + 1)/2 = ( 5 - m)/3

3(m + 1) = 2(5 - m)

3m + 3 = 10 - 2m

3m + 2m = 10 - 3

5m = 7

m = 7/5

5)cross multiply

= 8(x + 1) = 3(2x + 3)

8x + 8 = 6x + 9

8x - 6x = 9 - 8

2x = 1

x = 1/2
