You have $200 on a savings account and$100 in a checking account each week you add $50 to your savings account and $30 to your checking account write an expression in simplest form that represents the total amount of money in both accounts after w weeks

The expression is (80w+300)

Step-by-step explanation:

Let

y > the total amount of money in both accounts

s > the  amount of money in saving account

c > the amount of money in checking account

w > the number of weeks

we know that

saving account

s=50w+200 > equation A

checking account

c=30w+100 > equation B

To find out the total amount of money in both accounts, sum equation A and equation B

y=s+c

substitute

y=(50w+200)+(30w+100)

y=(50w+30w)+(200+100)

y=80w+300

therefore

The expression is (80w+300)

(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
