Answer from: Quest

$\boxed{\bold{2240a^4u^{18}w^3x^4}}$

explanation:

remove parenthesis: $\bold{\left(a\right)=a,\: -\left(-a\right)=a}$

= $\bold{4u^9w^1\cdot \: 7x^4\cdot \: 4a^3w^2\cdot \: 8\cdot \frac{1}{2}a^1\cdot \: 5u^9}$

apply rule $\bold{a^1=a}$

= $\bold{4\cdot \: 7\cdot \: 4\cdot \: 8\cdot \: 5\cdot \frac{1}{2}a^3au^9u^9w^2wx^4}$

multiply fractions: $\bold{\: a\cdot \frac{b}{c}=\frac{a\: \cdot \: b}{c}}$

= $\bold{\frac{1\cdot \: 4u^9w\cdot \: 7x^4\cdot \: 4a^3w^2\cdot \: 8a\cdot \: 5u^9}{2}}$

$\bold{1\cdot \: 4u^9w\cdot \: 7x^4\cdot \: 4a^3w^2\cdot \: 8a\cdot \: 5u^9: \ 4480x^4w^3a^4u^{18}}$

= $\bold{\frac{4480a^4u^{18}w^3x^4}{2}}$

divide: $\bold{\frac{4480}{2}=2240}$

= $\bold{2240a^4u^{18}w^3x^4}$

Answer from: Quest

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max. it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to. the number combination of adults (x) and campers (y) cannot exceed this 525 max. therefore:

x + y ≤ 525

now we talk about cost. it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults. same with the campers, who cost $5 to feed. the adults can be represented by 9x and the campers can be represented by 5y. since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200

Answer from: Quest

vince wrote the sequence below.

1/3, 1, 5/3, 7/

which of the following explains whether the sequence is geometric?

the sequence is geometric because 2/3 was added to each term to get the next term.

the sequence is geometric because 3 was multiplied to each term to get the next term.

the sequence is not geometric because 2/3 was added to each term to get the next term.

the sequence is not geometric because 3 was multiplied to each term to get the next term.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
