Answer: Andrew = 90 pounds
Explanation:
Assume Andrew weight is X
Since Jackson weight is 3 times Andrew
Then it’s 3x
3x + x = 360
4x = 360
x = 90
Subtract 5 from both sides
a/-8 = 4/7 - 5
simplify 4/7 - 5 to 31/-7
a/-8 = 31/-7
multiply both sides by 8
-a = 31/-7 x 8
simplify 31/7 x 8 to 248/7
-a = 248/7
multiply both sides by -1.
The answer is a = 248/7

Answer:
520 houses
Step-by-step explanation:
Here, we are interested in calculating the number of houses in the town.
We are told that the density is 8 houses per block and there are 65 blocks
The number of houses in the town = density * number of blocks = 65 * 8 = 520 houses
When grades are expressed as a quantity of 1, such as two feet per second or 5 miles per hour, they are called unit rates.
The number of plates is an illustration of permutation and combination
The number of plates is 2592
<h3>How to determine the number of plates</h3>
The range is given as: AVVJ 144 To: BVNP 199 (exclusive)
From the range, we have the following highlights:
- The first letter can be either A or B (i.e. 2 letters)
- The second letter can be only V (i.e. 1 letter)
- The third letter can be from W to M (24 letters)
- There are 54 numbers between 144 and 199
The number of plates (n) is then calculated as:
Evaluate the product
Hence, the number of plates (n) is 2592
