Answer:
x=23, y=13
Step-by-step explanation:
x+y=36
x-y=10
23+13=36
23-13=10
Answer:-7
Step-by-step explanation:
24-8i=10-10i
24-10=-10i+8i
14=-2i
I=-7
0.625 = 0.625 / 1
Numerator = 0.625 × 10 × 10 × 10 = 625
Denominator = 1 × 10 × 10 × 10 = 1000
Numerator / Denominator = 625 / 1000
Our simplifed fraction is:
= 625/1000
= 5/8
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
