If 40q=p+p÷3+p÷9+p÷27 find the ratio of q to p help please I don't get it.

8_murik_8 [283]

We must follow "PEMDAS" rules for "order of operations."

Multiplication and division must be done before addition and subtraction:

40q = p + (p/3) + (p/9) + p/27

The LCD of this expression is 27. 1, 3 and 9 all divide evenly into 27. The equation thus becomes:

27(40q) = 27p + 9p + 3p + p

Adding up the four "p" terms, we get 40p. Then 27(40q) = 40p.

Simplifying thru division by 40, 27q = p. Alternatively, p = 27q.

Find the ratio of p to q by dividing both sides by q: (p/q) = 27 (answer)

Alfonso solved a division problem by drawing an area model . a. Look at the area model . What division problem did Alfonso solve

r-ruslan [8.4K]

Answer:

The answer is " $\frac{72}{4} =18$ ".

Step-by-step explanation:

Given value:

4 40 32

Solution:

${\boxed{4\ \boxed{40} \ \boxed{32}}}$

If we divide the value by 4 it will give 10 and 8.

$\to \frac{40}{ 4} = 10\\\\\to \frac{32}{ 4} = 8\\$

If we add the boxed value it will be equal to 72 and divide the value by 4 it will give a value 18.

$\to 40+32 =72\\\\\to \frac{72}{4}=18$

The lines graphed below are parallel.the slope of the slope of red line is 2/5 .what is the slope of the green line

Yuliya22 [10]

Answer:

$\large\boxed{\text{the sloe}\ m=\dfrac{2}{3}}$

Step-by-step explanation:

$\text{Let}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\l\ \parallel\ k\iff m_1=m_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}$

$\text{We have the slope}\ m_1=\dfrac{2}{5}.\\\\\text{The slope of parallel line is the same:}\ m_2=\dfrac{2}{5}$
