The expression (1.2x + 4) represents the number of miles Angie jogged during a race, and 3x represents the number of miles that

zhannawk [14.2K]

<h3>Answer: 1.8x - 4</h3>

==========================================================

Explanation:

Subtract the two expressions

Tomas - Angie = (3x) - (1.2x+4) = 3x - 1.2x-4 = 1.8x-4

This represents how many more miles Tomas jogged compared to Angie.

-------------

A more concrete example would be to say hypothetically

Tomas = 10 miles

Angie = 4 miles

So Tomas - Angie = 10-4 = 6 means he jogged 6 more miles than Angie.

That's why we subtracted. The order of subtraction matters. Saying 10-4 is different from 4-10.

Ket [755]

Answer:

See explanation

Step-by-step explanation:

We want to show that:

$\tan(x + \frac{3\pi}{2} ) = - \cot \: x$

One way is to use the basic double angle formula:

$\frac{ \sin(x + \frac{3\pi}{2} ) }{\cos(x + \frac{3\pi}{2} )} = \frac{ \sin(x) \cos( \frac{3\pi}{2} ) + \cos(x) \sin( \frac{3\pi}{2}) }{\cos(x) \cos( \frac{3\pi}{2} ) - \sin(x) \sin( \frac{3\pi}{2}) }$

$\frac{ \sin(x + \frac{3\pi}{2} ) }{\cos(x + \frac{3\pi}{2} )} = \frac{ \sin(x) ( 0) + \cos(x) ( - 1) }{\cos(x) (0) - \sin(x) ( - 1) }$

We simplify further to get:

$\frac{ \sin(x + \frac{3\pi}{2} ) }{\cos(x + \frac{3\pi}{2} )} = \frac{ 0 - \cos(x) }{0 + \sin(x) }$

We simplify again to get;

$\frac{ \sin(x + \frac{3\pi}{2} ) }{\cos(x + \frac{3\pi}{2} )} = \frac{- \cos(x) }{ \sin(x) }$

This finally gives:

$\frac{ \sin(x + \frac{3\pi}{2} ) }{\cos(x + \frac{3\pi}{2} )} = - \cot(x)$

A garden table and a bench cost 816 combined. The garden table costs 84 less than the bench. What is the cost of the bench?

klemol [59]

Answer:

366

Step-by-step explanation:

A garden table and bench cost 816 when combined together

The garden table cost 84 less than the bench

Therefore the price of the bench can be calculated as follows

x + (x+84)= 816

2x+84= 816

2x= 816-84

2x= 732

Divide both sides by 2

x= 732/2

= 366

Hence the price of the bench is 366
