7. Francis made 7 withdrawals of $75 each from his bank account.
What was the overall change in
his account?

-$525

Step-by-step explanation:

7x = how many times he withdrew money * how much money he withdrew.

7 * 75 = $525

Francis ended up removing $525 from his bank account, if we assume that he started off with $0- then the change would be -525 dollars.

ok

step-by-step explanation:

(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
