Answer:
9x^2
Step-by-step explanation:
It is given that:
x ( x + y ) = 27
If one manipulates the equation, by dividing by x, they get:
x + y = 27/x
It is also given that:
y ( x + y ) = 54
Again, manipulate the equation, only this time, divide by y,
x + y = 54/y
It is obvious that;
x + y = x + y
Yet this was proven;
x + y = 27/x
x + y = 54/y
Therefore, the following has to be true;
27/x = 54/y
To sove the proportion, use cross products;
27/x = 54/y
54x = 27y
Inverse operations:
54x = 27y
/27 /27
y = 2x
Substitute;
(x + y)
y = 2x
= (x + 2x)
= 3x
Now solve:
(3x)^2
9x^2

The expression in simplified form, obtained from the distributive property of multiplication over addition is; 15·m - 30
What is the distributive property?The distributive property of multiplication over addition states that for numbers, a, b, and c, we get;
a·(b + c) = a·b + a·c
The expression, 5·(3·m - 6) can be simplified by applying the distributive property of multiplication as follows;
5·(3·m - 6) = 5 × 3·m + 5 × (-6) = 15·m - 30
The simplified form of the expression is therefore; 15·m - 30

The event coordinator asks you to determine how many students participated in the
track-and-field day. The total number of students in seventh and eighth grade
combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth-graders. If 4/8 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answer:
374.125 students. Not sure if you're supposed to round up or down considering you can't have a fraction of a person, but I would round down.
Step-by-step explanation:
(5/8) (584) = 365 seventh graders in total
(3/8) (584) = 219 eighth graders in total
(4/8) (365) = 182.5 seventh graders who participated in track-and-field day
(7/8) (219) = 191.625 eighth graders who participated in track-and-field day
182.5 + 191.625 = 374.125 students in total who participated
Answer:
First, I took 5/8 out of 584 for the seventh graders which came out to 365 seventh graders. Then, I did the same thing with 3/8 and it came out to 219 eighth graders. Then I took out 4/5 out of 365 which resulted as 292. Then I did the same thing for 7/8 and the results came out as 191. So in total 483 students participated in track-and-field day.

Amil took $65.00 to go shopping, and he bought 2 pair of jeans for $27.00 each. How much change will he have? Choose the expression that is a correct translation of the problem.
(2 x 27) - 65
65 – (2 x 27)
65 – (2 + 27)
65 – 2 + 27
Answer:
B) 65 – (2 x 27)
Step-by-step explanation:
65 is you total, 2 is the amount of jeans and 27 is the individual price of the jeans.
Since you want to know how much is left over, you subtract how much you spent which would be, in this case, the jeans.
You bought 2 jeans, each for 27 dollars so you multiply the two to see how much for both jeans.
Subtract that from the total.
Hope this helps! (^-^)
Answer:
65-(2 x27)
Step-by-step explanation:
You already know that Amil has 65$ so that's the first part.
And then it tells you that he bought 2 pairs of jeans and the price.
So if u multiply how many jeans he got times the price that tells you how much it cost. So it cost 54$
Last but not least you subtract 54$(the price) from 65$(how much money he had) to get the amount of change left over.

2 : 5
Answer:
The answer is 3:5
Step-by-step explanation:
Since the Ratio is to flour tortillas to total, we already know that the number of flour tortillas is 3.
The total number is 5. If you add up both flour tortillas and corn tortillas the total number would be 5.
The ratio would be 3:5
