Solve the system of equations 2r + 2s = 50 and 2r – s = 17. A. r = 3, s = 11 B. r = 25, s = 33 C. r = 14, s = 11 D. r = –8, s =
scZoUnD [109]

2r = 17 + s = 50 - 2s \\ 3s = 50 - 17 = 33 \\ s = 11 \\  \\2 r = 50 - 2s \\ 2r = 50 - 2 \times 11 = 50 - 22 = 28 \\ r = 14

Determina si 2018 es un termino de la siguiente progresion aritmetica 17,46,75,104,133,....
Kitty [74]
2018 is the 70th term of the progression.

Explanation
We start out finding the common difference of the progression:
46-17 = 29

Now we write the explicit formula for the sequence.  It is of the form
a_n=a_1+d(n-1)
\\
a_n=17+29(n-1)

We set this equal to 2018 to see if the answer is a whole number.  If it is, it will be the term number that gives us 2018:

2018=17+29(n-1)

Using the distributive property,
2018=17+29*n-29*1
2018=17+29n-29

Combine like terms:
2018=29n-12

Add 12 to both sides:
2018+12=29n-12+12
2030=29n

Divide both sides by 29:
2030/29=29n/29
70=n

Since n=70, this means 2018 is the 70th term of the sequence.

11. If you want to enlarge a square with area 36 square inches
larisa86 [58]

Answer:

e. 72 inches

Step-by-step explanation:

Well, firstly to find the lengths of the sides, we would have to find the square root of 36 (which is 6, as 6x6=36).

Now, if we enlarge the square by SF 3, the new side lengths would be 6x3=18 inches. That is only one side.

Now we know the length of one side, we can do 18x4 (because as we all know, squares have 4 sides) to find the perimeter.

18x4=72 inches. This means the answer is option e.
