-5x - 3(-4x - 9) = 83
Add 5x to both sides
-3(-4x-9) = 83 + 5x
Divide by -3
-4x-9 = 83/3 + 5/3x
Subtract 5/3x
-4x -5/3x -9 = 83/3
Add 9
-17/3x = 110/3
Multiply by 3
-17x = 110
Divide by -17
X = 6 and 8/17

-5x-3(-4x -9)= 83

Distribute. 

-5x+12x+27= 83 (two negatives equal a positive) 

Combine like terms.

7x+27= 83

Subtract 27 from both sides.

7x= 56

Divide 7 into both sides.

x=8

I hope this helps!

Solve for C.<br> 5/4= -4c + 1/4
dybincka [34]
5/4= -4c + 1/4

Inverse operation

\frac{5}{4} = -4c + \frac{1}{4}

- 1/4             -1/4

5/4 - 1/4 = 4/4

\frac{4}{4} = -4c
-4c/-4  = 4/4 ÷ -4/1 

4/4 *- 1/4 = c
-4/8 = c
c = -1/2

Answer:  c = - \frac{1}{2}

Answer:

The unit rate is accurately \frac{1}{4} (km/minute)

Step-by-step explanation:

(1,1/4) means that the vehicle traveled 1/4 km within 1 minute.

The unit rate for this problem is also known as the speed of the vehicle.

So to find the speed, you need to use distance over time.

---> Unit rate: \frac{1}{4}\\ / 1 = \frac{1}{4} (km/minute)

(2,1/2) means that the vehicle traveled 1/2 km within 2 minutes.

Same process:

---> Unit rate: \frac{1}{2} / 2 =

Because of this, the unit rate is accurately \frac{1}{4} (km/minute)

The x3 was supposed to be an exponent not 3x
mote1985 [20]

Answer:

The value of x is 2\sqrt[3]{2}

Step-by-step explanation:

We are given 2+x^3=18

We need to solve for x

First we subtract 2 both sides

x^3=18-2=16

Taking cube roots both sides to isolate x

x=\sqrt[3]{16}

Simplify the radical

x=2\sqrt[3]{2}

Thus, The value of x is 2\sqrt[3]{2}
