2p/9 + 5p/18 - 5/6 = 2/3 + p/12 + 1/6

mezya [45]

$\frac{2p}{9}+\frac{5p}{18}-\frac{5}{6}=\frac{2}{3}+\frac{p}{12}+\frac{1}{6}\ \ \ |Multiply\ by\ 36\\\\
4*2p+2*5p-5*6=12*2+3*p+6*1\\\\
8p+10p-30=24+3p+6\\\\
18p-30=3p+30\ \ \ |Subtract\ 3p\\\\
15p-30=30\ \ \ |Add\ 30\\\\
15p=60\ \ \ |Divide\ by\ 15\\\\
\boxed{p=4}$

Evaluate the expression. 5 x (-6 / -1 + -10)

kotykmax [81]

Answer:

-20

Step-by-step explanation:

$5 * (-6 / -1+ -10)$

According to PEMDAS, we need to do the math in the parentheses first.

$-6 / -1 + -10$

Applying PEMDAS to the inside of the parentheses, then we have to divide -6 by -1, where we would get 6.

$6 + -10$

Adding a negative is the same as subtracting, so adding negative 10 is the same as subtracting 10.

$6 - 10$

Subtracting, we get 6 - 10 = -4 and we're left with:

$5 * (-4)$

Multiplying, <u>our final answer is -20.</u>

Hope this helps!
