34 = 10 + 4q Solve Need help

LiRa [457]

Simplifying

34 = 10 + 4q

Solving

34 = 10 + 4q

Solving for variable 'q'.

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

Add '-4q' to each side of the equation.

34 + -4q = 10 + 4q + -4q

Combine like terms: 4q + -4q = 0

34 + -4q = 10 + 0

34 + -4q = 10

Add '-34' to each side of the equation.

34 + -34 + -4q = 10 + -34

Combine like terms: 34 + -34 = 0

0 + -4q = 10 + -34

-4q = 10 + -34

Combine like terms: 10 + -34 = -24

-4q = -24

Divide each side by '-4'.

q = 6

Simplifying

q = 6

Find the area and the perimeter of a rectangle with a length of 5 feet and a width of 4 5/9 feet. Write each answer as a fractio

Over [174]

$\bf \textit{area of a rectangle}\\\\ A=Lw~~ \begin{cases} L=5\\ w=4\frac{5}{9}\\[0.8em] \qquad \frac{4\cdot 9+5}{9}\\[0.8em] \qquad \frac{41}{5} \end{cases}\implies A=5\cdot \cfrac{41}{5}\implies \stackrel{fraction}{A=\cfrac{41}{1}}\implies \stackrel{decimal}{A=41} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \textit{perimeter of a rectangle}\\\\ A=2(L+w)\qquad \implies A=2\left(5+\cfrac{41}{5} \right) \implies A=2\left( \cfrac{25+41}{5} \right) \\\\\\ A=2\left( \cfrac{66}{5} \right)\implies A=\cfrac{132}{5}\implies \stackrel{fraction}{A=26\frac{2}{5}}\implies \stackrel{decimal}{A=26.4}$
