**Step-by-step explanation:**

**Answer:**

2.294117647

**Step-by-step explanation:**

3/17 = u/13

Cross multiply:

3 * 13 = 17 * u

Simplifying

3 * 13 = 17 * u

Multiply 3 * 13

39 = 17 * u

Solving

39 = 17u

Move all terms containing u to the left, all other terms to the right.

Add '-17u' to each side of the equation.

39 + -17u = 17u + -17u

Combine like terms: 17u + -17u = 0

39 + -17u = 0

Add '-39' to each side of the equation.

39 + -39 + -17u = 0 + -39

Combine like terms: 39 + -39 = 0

0 + -17u = 0 + -39

-17u = 0 + -39

Combine like terms: 0 + -39 = -39

-17u = -39

Divide each side by '-17'.

u = 2

Simplifying

u = 2.294117647

**Step-by-step explanation:**

The expression that shows how many peanut butter

cupcakes she baked is 5 (2x-4) + 3(3+4x).

To simplify this, we need to use the distributive property:

We expand using the distributive property to get:

We group similar terms on the right to obtain:

Combine similar terms on the right to get:

Therefore the simplified expression is
