Answer:
C - 21:28
Step-by-step explanation:
this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.
For C I did this:
Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.
Let's test it out for the numerator now. 21 ÷ 15 = 1.4.
So there's your answer.

45÷5=9
Answer:
6S + 11C = $120
2S + 1 C = $24
So solve equation 2 for C
C = 24 - 2 S
Subsitute in to eq 1
6S + 11(24-2S) = 120
6S + 264 -22S = 120
264 -16S =120
264 -120 = 16S
S = (264-120)/16 = 144/16 = $9
c = 24 - 2S = 24 - 2x9 = 24-18 = $6

Answer:
40 or 16+6+6+6+6
Step-by-step explanation:
To find the surface area of a 3d figure, we can imagine all of its faces laid down on a flat plane. In this case, we would have a square, and four congruent triangles. Now all we have to do is find the areas of each shape and add them up.
4 is the base of the pyramid, so it's also the square's side length. Since a square has four equal sides, our square's length and width are both 4.
4*4 = 16
For every triangle we have, the base is 4 and the height is 3. The area of a triangle can be found using the formula A=(bh)/2. We plug in the values:
A = (4*3)/2
A = (12)/2
A = 6
Since we have 4 triangles, the surface area is:
16+6+6+6+6 = 40
