4(5x + 7) = 128

First, I'd do distributive property and get:

20x + 28 = 128

Then, subtract 28 from each side.

20x = 100

Next, I'd divide 100 by 20 = 5

x = 5

4 *(5(5) + 7) = 128

5 * 5 = 25

4 * (25 + 7)

4 * 32 = 128

Therefore, the perimeter = 2l + 2w

l = 4

w = 5x + 7

BUT we know that x = 5

w = 5(5) + 7 = 32

2(4) + 2(32)

8 + 64 = 72

Therefore, the perimeter would be 72 inches.

A total of 754 tickets were sold for the school play. They were either adult tickets or student tickets. There were 54 more tick
Veseljchak [2.6K]

Answer:

Answer: 350

Step-by-step explanation:

Explanation:

a = adult tickets

s = student tickets

║ a + s = 754

║s = a + 54

Plug s = a + 54 into a + s = 754

a + (a + 54) = 754

a + a + 54 = 754

2a + 54 = 754

2a = 754 - 54

2a = 700

a = 350

\dfrac{2}{18} - \dfrac{15}{18}

  • Get all fractions to a common denominator which will allow you to subtract them

\dfrac{2 - 15}{18}

  • Subtract numerators

\boxed{- \dfrac{13}{18}}

  • Simplify
