8 A teacher writes the algebraic expression 24c + 5m + 19.99 to represent the cost
of supplies she purchased for her classroom. She bought 24 packages of colored
pencils, 5 packages of markers, and a beanbag chair. Identify any variables,
coefficients, and terms in the expression. Tell what each represents.
9 Write a situation that could be represented by the algebraic expression 3s + 2.15.

24c= 24 'c'olored pencils, 5m= 5 packages of 'm'arkers, 19.99= cost of one bean bag chair

The cost of 3 's'nakes plus the cost of food for all three of them

Step-by-step explanation:

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

(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
