Step-by-step explanation:
let,the sum of the ages of chukwu & Caroline be X & Y.
now,
X+y=45
X-y=3
(+) (+) (-)
__________
2x=42
or,X=42/2
or,X=21
putting the value of X,
X+y=45
or, 21+y=45
or,y=45-21
or,y=24
therefore,X=21
y=24
Sharing three apples between 5 people gives each person 3/5 of an apple (or .6 or 60%.)
Answer:
5=-3+y
inverse property. -3 + 3 = 0 so we add 3 to both sides to cancel out the -3 to ISOLATE the y.
5 = -3 + y
-3 + 3
-3 + 3 = 0
5+3 = 8
8 = y.
y = 8 basically. I hope that helped.
Step-by-step explanation:
The mean increases by two.
15+23+24+26+27+35 = 140
140/6 = 23.3
23+24+26+27 = 100
100/4 = 25
The mean roughly increases by 2.
1. 14 - 25/p
2. 3w + 4t
3. 13m + 14n
4. 2a . 5b
