Iam not sure about this questions answer can u give answer
Q10,11,12

10. First you multiply both sides by 3, making it 2x + 5 = 24

Then you subtract 5 from both sides making it 2x = 19

You dive both sides by 2 making x = 9.5

The answer is x = 9.5

11. First you need to find how much you need to pay each year. 12,000 x 0.05

you can make it easier by changing it to 120 x 5 = 600

You need to pay that for three years so 600 x 3 = 1800

Plus you need to pay the original money. 12,000 + 1,800 = 13,800      

The answer is $13,800    

12. First you change kilometers into centimeters. 172 km is 172,000 meters. 172,000 meters is 17,200,000

Then, you need to do 17,200,000 ÷ 500,000 but you can make it simple and do 172 ÷ 5 = 34.4

The answer is 34.4 cm

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the monthly balance will be $75,000
