Answer:

x > -1

Step-by-step explanation:

To solve the inequality, use the same rules as solving equations.

2 - 2x < 4

-2x < 2

x > -1

Since you divide by a negative, you must switch the sign < to >.

Linear equation using substitution x=16-4y 3x+4y=8

jarptica [38.1K]

If x=16-4y then in your other equation 3x+4y=8 you can put that where x is to get:

3(16-4y)+4y=8

Then multiply brackets to get:

48-12y+4y=8

Simplify:

48-8y=8

Rearrange:

40=8y

Divide through by 8:

y=5

Then put y=5 back into x=16-4y to get x:

x=16-4(5)
x=16-20
x=-4

2. In the circle graph above, you can see that 47% of the company's monthly income is used to pay the owner's personal salary. I

Lerok [7]

So whe have $\frac{47}{100}$ that is paid to the boss.

The boss won 2,176.10 this month. $\frac{2,176}{x}$
So our equation would end as...
$\frac{47}{100}=\frac{2,176}{x}$

We solve what can be solved...
0.47=\frac{2,176}{x}

Then we leave our unknown value alone...
0.47x=2,176
x=\frac{2,176}{0.47}

Last we solve...
x= 4,629.79
x≈4,630

So the answer is A.
