Carmine buys 3 plates for $2 each. He also buys 10 bowls. Each bowl costs twice as much as each plate. The store is having a sale that gives Carmine $3 off the total cost of the bowls.
Which numerical expression shows how much he spent?
(3 * $2) + (10 ($6 - $3)]
A
(3 * $2) + [(10 $6) - $3]
B
(3 x $10) + [(10 $4) - $3]
с
D
(3 * $2)+((10 $4) - $3]

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

think about it deeply and passionately about this property

i am sorry

(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
