Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an

marishachu [46]

Answer: $x+x^2+x^3+x^4$

Step-by-step explanation:

As per given,

Number of wives = $x$

Number of sacks = $x (\text{Number of wives} )= x\times x = x^2$

Number of cats = $x(\text{Number of sack})$ $= x \times x^2=x^3$

Number of kits = $x(\text{Number of cats} )=x\times x^3=x^4$

Now , the total number of kits, cats, sacks, and wives going to St. Ives = $x+x^2+x^3+x^4$

Hence, the required ex[pression: $x+x^2+x^3+x^4$

Which number line represents the solutions to –2|x| = –6? A number line from negative 8 to 8 in increments of 1. Two points, one

Elenna [48]

|–2x| = -6

=> 2x = 6

=> x = 3

and,

=> 2x = -6

=> x = -3.

Two points, one at negative 3 and one at 3.

If coal is mined at $35.99 per short ton, how much is the price per kg? Use dimensional analysis to solve. 1 short ton = 907 kg.

cricket20 [7]

The cost of 1kg of coal mined from the ore is $0.0397

Data;

1 ton = $35.99
1kg = ?

To find the cost of 1kg of coal, we can simply and equate 1 ton to its equivalent in ton and the solve.

$1ton = 907kg\\$

let's write this and equate it

1 ton = $35.99

907kg = $35.99

1kg = x

Let's cross multiply both sides and solve for x

$907kg = \$35.99\\1kg = x\\x = \frac{1 * 35.99}{907} \\x = \$0.0397$

The cost of 1kg of coal is $0.0397
