Answer:

A and C are the correct answers.

Step-by-step explanation:

Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.

In choice A, since 3z has a variable, it goes before 1.
In choice C, since -5p^5 has the highest exponent it does go first.
Then 2p^2, since it has the second highest exponent.
Then -3p follows, with the lower exponent.
Then 1 goes last because it has no variable and has the lowest exponent.

Answer: r=16

Step-by-step explanation:

r-29=-2r+19

r=−2r+19+29

r=−2r+48

r+2r=48

3r=48

r=48/3

r=16

A woman is q years old while her son is p years old. the sum of their ages is equal to twice the difference of their ages. the p

Allisa [31]

Step-by-step explanation:

Given

$q + p = 2(q - p)$

as equation 1.

I used q-p as the difference as logically the woman will be older than her son.

Also given,

$qp = 675$

as equation 2.

Using equation 2,

$q = \frac{675}{p}$

substitute this equation into equation 1.

$\frac{675}{p} + p = 2( \frac{675}{p} - p) \\ \frac{675}{p} + p = \frac{1350}{p} - 2p \\ \frac{675}{p} - \frac{1350}{p} = - 2p - p \\ - 3p = - \frac{675}{p} \\ - 3p \times p = - 675 \\ - 3 {p}^{2} = - 675 \\ {p}^{2} = - 675 \div - 3 \\ {p}^{2} = 225 \\ p = \sqrt{225} \\ = 15$

Substitute P into equation 2.

$15q = 675 \\ q = 675 \div 15 \\ = 45$

Therefore the woman is 45 years old while her son is 15 years old.
