2a+1:14::4:7 then a=?​

Answer 1

Answer:

A=7/2=3.5

Step-by-step explanation:

2A+1:14 : : 4:7

7(2A+1)=14X4

2A+1=( 14X4)/7

2A+1 = 8

2A=8-1

A=7/2=3.5

Answer 2

Answer:

$a = \frac{7}{2}$

Step-by-step explanation:

$\frac{2a + 1}{14} = \frac{4}{7}$

7(2a + 1) = 4× 14

14a + 7 = 56

14a = 56– 7

14 a =49

a= 49/14

a= 7/2
