6x+4y=42 -3x+3y=-6 by elimination
creativ13 [48]

Answer:

x=5, y=2

Step-by-step explanation:

To solve this system, we need to find x and y. First, let's find x. In the first equation (6x+4y=42), subtract 4y on both sides to isolate 6x. This will result in 6x=42-4y. Divide by 6 on both sides to isolate x and get x=7-\frac{2}{3}y. Now we know what x equals. Go to the second equation ad plug this into it. So instead of -3x+3y=-6, you'll have -3(7-\frac{2}{3}y)+3y=-6. Use the distributive property to get -21+2y+3y=-6. Add 2y and 3y to get -21+5y=-6. Add 21 to both sides to isolate 5y and get 5y=15. Divide by 5 on both sides to isolate y and get y=3. Now that we know that y=3, we can plug this back into the equation that was bolded above so that we can find x, so we'll have x=7-\frac{2}{3}(3) since y=3, and we'll get x=7-\frac{6}{3}, or x=7-2, or x=5.

x=5

y=2

Students are getting signatures for a petition to increase sports activities at the community center. The number of signatures t
ohaa [14]

Answer:

The students got 3 signatures on first day.

Step-by-step explanation:

We are given the following in the question:

The number of signatures students get each day is 3 times as many as the day before.

Thus, the number of signatures form a geometric progression with common ratio 3.

r = 3

Number of signatures on sixth day = 3^6

n^{th} term in a geometric progression is given by:

a_n = ar^{n-1}

where a is the first term of the series and r is the common ratio.

a_6 = 3^6\\3^6 = ar^{5}\\3^6 = a(3)^5\\a = 3

Thus, the first term of geometric progression is 3.

Thus, the students got 3 signatures on first day.
