Which expression is equivalent to 10x2y + 25x2?5x2(2y + 5)
5x2y(5 + 20y)
10xy(x + 15y)
10x2(y + 25)
Answers
The expression 10x^2y + 25x^2 is an algebraic expression, and the equivalent expression of 10x^2y + 25x^2 is 5x^2(2y + 5)
What are equivalent expressions?
Equivalent expressions are expressions that have equal values, when evaluated
The expression is given as;
10x^2y + 25x^2
Factor out 5x^2
10x^2y + 25x^2 = 5x^2(2y + 5)
The above means that the equivalent expression of 10x^2y + 25x^2 is 5x^2(2y + 5)

How is 60 divided by 9 = 6.66666667?
Answers
g(x) = -x + 3
f(g(x)) = 9(-x + 3) - 2
f(g(x)) = 9(-x) + 9(3) - 2
f(g(x)) = -9x + 27 - 2
f(g(x)) = -9x + 25
So: f(g(x)=-9x+27-2=-9x+25

The formula is then therefore, r = k/w
Solve for constant first.
r = k/w
20 = k/10
200 = k
r=200/5
r=40 roses
40 roses when there are 5 weeds.
Answer:
The Inverse variation says that:
,
then the equation is of the form:
or
Here, r represents the number of roses and w represents the number of weeds.
As per the statement:
The number of roses (r) in a garden increases when the number of weeds (w) decreases.
by definition of inverse variation:
....[1]
From the given table:
take any points
r = 20 and w = 10 then;
Substitute in [1] we have;
Simplify:
k = 200
The equation becomes:
We have to find the number of roses when there are 5 weeds.
⇒w = 5
then;
Divide both sides by 5 we get;
r = 40
Therefore, the number of roses are 40 when there are 5 weeds.

=> $8 per hour by tutoring
=> $7.50 per hour by walking the dogs
=> You have 15 hours available
=> You need to make atleast $115 in walking the dogs.
let’s assign a variable to use.
Let a = tutoring
Let b = walking the dogs
=> a + b = 15
=> 8a + 7.5b = 115
=> 8a + 7.5(15 - a) = 115
=> 8a = 112.5 = 115
=> 8a = 115 – 112.5
=> 8a = 2.5
=> 8a / 8 = 2.5 / 8
=> a = 0.3125
=> b = 15 – 0.3125
=> b = 14.6875

14.6875

Answer: first option, 1/4.
Explanation:
1) Every drop is an independent event. So, the joint probability is the product of the individual probabilities.
2) The fact that the piece ot toast landed once time with the cream cheese side up, does not affect the next two drops.
3) Since, the piece of toast landed the first time with cream cheese side up, the probability that it it will have landed cream cheese side up a total of three times is the probability that it will have landed two more times with cream cheese side up.
3) The probability that the piece of toast will have landed cream cheese side up two more times is 1/2 × 1/2 = 1/4. And that is the answer to the question.
However, be aware that this only works because it asked what the probability of it happening three times in a row. For example, if the question read, "What is the probability of this piece of bread landing butter side down, assuming it has already landed three times butter side down?", the answer would be 1/2 because the probability of previous incidents do not actually physically affect a future test.
Find the total number of acres Mrs. Chen owns, to the nearest hundredth of an acre and please explain how to do it.
Answers
77120 + 33500 = 412120 square feet
Divide this number by 43560 to get the number of acres.
412120/43560 = 9.46
Answer: 9.46 acres
77,120 + 33,500= 110,620
1 acre= 43,560
To find the total number of acres now, you divide 110,620 ÷ 43,560
and that equals about 2.54. (Since you asked for the nearest hundredth of an acre)
