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

We have 2 equations  here  ( b = cost of bush and  t = cost of a tree)

10b + 4t = 246........................................................(1)
5b + 3t = 147      Multiply this equation by -2:-
-10b - 6t = -294.......................................................(2)

Adding equations (1) and (2) we get:-

0 - 2t = - 48

t = -48/-2 = 24

Plug t = 24 into the first equation:-
10b + 4(24) = 246
10b = 246 - 96 = 150
b = 15 

The answer is one bush costs $15 and one tree costs $24.

Find the greatest and least number from 5,0,8,9 and 7​
Dvinal [7]

<u>Answer:</u>

  • Greatest number: 98750
  • Least number: 5789

<u>Explanation:</u>

<em>To find the greatest number with the following values, we must arrange the numbers in descending form. </em>

<em>=> We can clearly tell that the numbers in descending form is 9 > 8 > 7 > 5 > 0</em>

<u>Hence, the greatest number with the following numbers (5,0,8,9, and 7) will be 98750.</u>

<h3>__________________________________________________</h3>

<em>To find the least number with the following values, we must arrange the numbers in ascending form.</em>

<em>=> We can clearly tell that the numbers in ascending form is 0 < 5 < 7 < 8 < 9</em>

<u>Hence, the least number with the following numbers (5,0,8,9, and 7) will be 5789</u>

A fruit company delivers its fruit in two types of boxes: large and small. a delivery of 5 large boxes and 3 small boxes has a t
Hoochie [10]
Let's let the weight of a large box be L, and the weight of a small box be S.

We know that 5 large boxes and 3 small boxes is 120kg, so:
5L + 3S = 120

We also know that 7 large boxes and 9 small boxes is 234kg, so:
7L + 9S = 234

You can multiply the first equation by 3 to get:
15L + 9S = 360

See how now both equations have 9S? We can now subtract one from the other:
(15L+9S) - (7L+9S) = 360-234
8L = 126
L = 15.75

Now sub this value back into an equation:
(5x15.75) + 3S = 120
3S = 41.25
S = 13.75

Double check these values
(7x15.75) + (9x13.75)
= 110.25 + 123.75
=234, which is consistent with above.

So a large box is 15.75kg, and a small box is 13.75kg.

Hope this helped
