Answer:
Step-by-step explanation:
5s + 6c = 23.91
2s + 7c = 17.89
10s + 12c = 47.82
-10s - 35c = -89.45
-23c = -41.63
c = $1.81 for a large coffee
2s + 7(1.81) = 17.89
2s = 5.22
s = $2.61 for a scone
Answer 3 ten of numbers between -5/6,5/8
multiply there denominators by any number ...
-5/6×48= -40/48
5/8×48= 30/48
Hence
30/48,31/48,32/48,33/48,34/48,35/48,36/48,37/48,38/48,39/38.
Answer 4
1. x-5=9
X=9+5=14
2. 7= y+2
7-2=y
5=y
Answer 5 X/9=-2
X= -2×9
X= -18
5t= 30
t=30/5
t=6
hope it helps friend
