Answer:

$\boxed{ \text{B. 10 weeks, \$310 }}\\$

Step-by-step explanation:

We have two conditions:

$\begin{array}{lrcll}(1) & y & = & 25x + 60 & \\(2) & y & = & 30x + 10 & \\ & 25x + 60 & = & 30 x + 10 & \text {Set (1) = (2)} \\ & 50 & = & 5x & \text{Subtracted 25x from each side} \\& x & = & 10 &\text{Divided each side by 5} \\\end{array}\\$ $\\\boxed{ \textbf{The number of weeks is }x = 10}\\$

Bella: y = 25x + 60 = 25(10) + 60 = 250 + 60 = 310

Heather: y = 30x + 10 = 30(10) + 10 = 300 + 10 = 310

6n − 2(4n + 7) + 4 = -2

vodomira [7]

Answer:

n = -4

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

((6n - 2 • (4n + 7)) + 4) - -2 = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

-2n - 8 = -2 • (n + 4)

Equation at the end of step 3 :

-2 • (n + 4) = 0

Step 4 :

Equations which are never true :

4.1 Solve : -2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : n+4 = 0

Subtract 4 from both sides of the equation :

n = -4

One solution was found :

n = -4
