MrRissso [65]

The age of the van owned = 12 years

The age of the truck owned = 29 years

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?

Let us assume the number of years Laura has owned the van = S years

So, according to the question:

The number of years she has owned truck = S + 17 years

Now, Sum of the age of ( Truck + Van) = 41 years

⇒ (S + 17 years) + (S years) = 41 years

or, 2 S + 17 = 41

or, 2 S = 4 1 -1 7 = 24

or, S = 24/2 = 12 years

or, S = 12 years

Hence the age of the van owned = 12 years

The age of the truck owned = S + 17 = 12 + 17 = 29 years

4m≥m+9>-9+4m<br> Please answer urgent

Vsevolod [243]

Next time, please include the instructions.

This inequality could be broken into two parts:

4m $\geq$ m + 9 AND m + 9 > -9 + 4m

Focus first on the inequality m + 9 > -9 + 4m. subtract m from both sides, obtaining:

9 > -9 + 3m. Next, add 9 to both sides, obtaining: 18>3m, or m<6

Last step: Determine whether the inequality <span>4m≥m+9 is true if m<6.</span>
