Kathy=k
John=k+6
''Together their ages equal four times Kathys age.''
→k+6+k=4k ; 2k+6=4k ; 2k=6 ;k=3
Kathy=3
John=3+6=9
Answer:
70%
Step-by-step explanation:
We can first find the fraction
35/50
We know that percent is out of 100 so multiply the top and bottom by 100
35/50 * 2/2 = 70/100
The percent is 70%
2x=y
×+y=36
x=Ed's age
y=His brothers age
Then you plug in Y into the secound equation.
×+2×=36.
You then add the two x together.
3x=36
The to get x by itself you take 36 and dive by 3 to get 12.
x=12
Then plug 12 into the equation
12+y=36
Then get y by itself.
y=24.
So, Ed's age is 12 and Ed's brother's age is 24.
