Complete Question

On Tuesday Jack bought four boxes. On Wednesday half of all the boxes that he had were destroyed.

Write an expression for how many boxes Jack has now

A. 1/2b+4

B. 1/2+4b

C. 4b−1/2b

D. b+42/2

C. 4b−1/2b

Step-by-step explanation:

Let the number of boxes that Jack has be represented by b

In the question, we are told that:

• On Tuesday, Jack bought 4 boxes

Since 1 box = b

4 boxes = 4b

• On Wednesday , half of the boxes where destroyed.

= 1/2 b

The expression for how many boxes Jack has now is given as

Number of boxes Jack bought in Tuesday - half of the boxes destroyers on Wednesday.

This is expressed mathematically as:

4b - 1/2b

m∠vru = 80°

m∠urw = 15°

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
