Solve for c.<br><br> 2(c +1) = 10

coldgirl [10]

Answer:

c=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(c+1)=10

(2)(c)+(2)(1)=10(Distribute)

2c+2=10

Step 2: Subtract 2 from both sides.

2c+2−2=10−2

2c=8

Step 3: Divide both sides by 2.

2 = 8

c=4

) Tara earns twice as much per hour as Kayte.

Cerrena [4.2K]

Answer:

Austin's hourly wage is $8.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

Tara's hourly wage is x.

Kayte's hourly wage is y.

Austin's hourly wage is z.

Tara earns twice as much per hour as Kayte.

This means that $x = 2y$

Kayte earns $3 more per hour than Austin.

This means that $y = z + 3$

As a group, they earn $41 per hour.

This means that $x + y + z = 41$

What is Austin's hourly wage?

This is z.

$x + y + z = 41$

$y = z + 3$ and $x = 2y$ , so $x = 2(z + 3) = 2z + 6$

$x + y + z = 41$

$2z + 6 + z + 3 + z = 41$

$4z + 9 = 41$

$4z = 32$

$z = \frac{32}{4}$

$z = 8$

Austin's hourly wage is $8.
