Answer:

Jewel is 7 years old

John is 1 year old

Dave is 17 years old

Step-by-step explanation:

From the question we are told that:

Jewel age is J=7 years

John age J'=(D-16)years

Dave's age a Year ago

 D-1=2(J-1+J'-1)

So that Dave.s age this Year could be

 D=2((J-1)+(J'-1))+1

Simplifying Equation for Dave's age we have

 D=2((7)-1+(D-16)-1)+1

 D=2(6+D-15)+1

 D=2(D-9)+1

 D=2D-18+1

 D=17 Years

Dave is 17 years old

Therefore

Johns age is

 J'=(D-16)

 J'=17-16

 J'=1year old

John is 1 year old

Paul [167]

Answer: 12 h + 135

Step-by-step explanation: 7h +135 + 5h = ?h + ?​

                                             7h +5h +135

PLEASE HELP ME WITH THIS PROBLEM!!
Veronika [31]
Your answer would be 24, so you got it right.

This is because you need to find the lowest common multiple of 6 and 8, that is, the lowest number that divides by both 6 and 8.

We can do this by either writing out the multiples of 6 and 8 until you find a common one, or you can find the prime factors of 6 and 8 and multiply them:

6-> 3 × 2
8-> 2 × (4)->2 × 2

So we would need to do 3 × 2 × 2 × 2 = 3 × 8 = 24

I hope this helps!
