Answer: The Answer Is 9
Step-by-step explanation:
If 4x - 12 = 24, add 12 to 24, and divide 36 by 4.
Subtract 5 from both sides then you get -3r+9=-4r then add 3r to both sides then you get 9=-1r then divide both sides by -1 and you get r=-9

Answer: cup is $2.55
Saucer $0.55
Step-by-step explanation:
Cost of cup and saucer is $3.10
Let the cup be x
And saucer be y
I.e
X+y= 3.10......equation 1
Cup which is X is $2 more than the saucer
I.e x=2+y......equation 2
Substitute for X in equation 1
(2+y)+y=3.10
2+2y=3.10
2y=3.10-2
2y=1.10
Y=1.10/2
Y=$0.55
Substitute for y in equation 2
X=2+y
X=2+0.55
X=$2.55
Therefore
The cup is $2.55
The saucer is $0.55
