Answer 1

Answer:

$x = \frac{21}{4}$

Step-by-step explanation:

$\frac{2x+3}{15} = \frac{9}{10} \\ \\ (10)(2x + 3) = (9)(15) \\ 20x + 30 = 135 \\ 20x = 135 - 30 \\ 20x = 105 \\ x = \frac{105}{20} \\ \\ x = \frac{21}{4}$

Answer 2

Answer:

5.25

Step-by-step explanation:

15/10=1.5

9*1.5=13.5

13.5-3=10.5

10.5/2=5.25
