We can simplify both the numeric and literal parts.

It could be useful to rewrite the fraction as follows, to make clear what we're simplifying with what:

$\dfrac{28st}{-4t} = -\dfrac{7\cdot 4}{4}\cdot s \cdot \dfrac{t}{t}= -7\dfrac{4}{4}\cdot s \cdot \dfrac{t}{t}$

The fractions 4/4 and t/t simplify to 1, since the numerator and denominator are the same. So, we're left with

$\dfrac{28st}{-4t} =-7s$

Using the functions presented in the example, how much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

12345 [234]

Answer:

Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Step-by-step explanation:

Given : $C(a)=7500a-1500$ , $M(C)=0.9C- 50$ and $M(C(a))=6750a-1400$

To find : How much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

Solution :

$C(a)=7500a-1500$

Substitute a=1.5,

$C(1.5)=7500(1.5)-1500$

$C(1.5)=11250-1500$

$C(1.5)=9750$

Now, taking function $M(C)=0.9C- 50$

Substitute C=9750,

$M(9750)=0.9(9750)- 50$

$M(9750)=8775- 50$

$M(9750)=8725$

Now, taking function $M(C(a))=6750a-1400$

Substitute a=1.5,

$M(C(1.5))=6750(1.5)-1400$

$M(C(1.5))=10125-1400$

$M(C(1.5))=8725$

Therefore, Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Brighten is an expression that shows how to multiply 7 * 256 using expanded form and distributive property

charle [14.2K]

I am not familiar with "brighten" but this is how you can expand and use the distributive property:

7(256)

= 7(200 + 50 + 6)

= 7(200) + 7(50) + 7(6)

= 1400 + 350 + 30

= 1780
