Janine is twice as old as her brother mark at the center of their ages is 24 hot how old is janine

Let Marc's age be x. If Jeanine is twice as old as Marc, then her age will be 2x. If their ages added together are 24, then you can create the following equation:2x + x = 243x = 24x = 8Remember that x is Marc's age. So if Marc is 8, and Jeanine is twice as old, she will be 16.

Step-by-step explanation:

answer: 193

explanation:

200-7 = 193

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
