solve the system of equations by adding. checking your answer
2x+2y=2
3x-2y=43
the solution of the system is ( , )
Answers
Answer:
Step-by-step explanation:
This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:
2x + 2y = 2
3x - 2y = 43
-----------------
5x + 0y = 45, so x = 9
Use the value of x to solve for y:
2(9) + 2y = 2
y = -8
(x,y) = (2, -8)
Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Anthony can use while staying within his budget.
Answers
Answer:
x ≤ 3.5 gigabytes
Step-by-step explanation:
Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month.
Let us represent the number of gigabytes = x
Hence, our Equation is:
$56 + $4 × x ≤ $70
56 + 4x ≤ 70
Collect like terms
4x ≤ 70 - 56
4x ≤ 14
x ≤ 14/4
x ≤ 3.5 gigabytes
Therefore, the number of gigabytes Anthony can use while staying within his budget is less than or equal to 3.5 gigabytes

What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression
A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that the series is 9, 15, 21, ..., The 35th term of the sequence will be calculated as,
Sn = n /2 [ ( 2a + ( n - 1 ) d]
Sn = 35 / 2 [ ( 2 x 9 + ( 35 - 1 ) 6)]
Sn = 35 /2 { 18 + ( 34 x 6 ) ]
Sn = 35 / 2 x 222
Sn = 3885
Hence, the sum of the 35 terms of the series will be 3885.

please show work
Answers
Answer:
-1/5
Step-by-step explanation:
Divide the numbers:
2/2n + 1 = 4/5
1n + 1 = 4/5
Multiply by 1:
1n + 1 = 4/5
n + 1 = 4/5
Subtract 1 from both sides of the equation:
n + 1 = 4/5
n + 1 -1 = 4/5 -1
Simplify:
N + 1 - 1 = 4/5 -1
N = 4/5 -1
N = 4/5 -1
And this is what you'll get:
N = -1/5

Given data
Dimension for the room
Length= 21 ft
Width= 17ft
Area= L*W
Area= 21*17
Area= 357 ft^2
Lucy will need to get 357ft^2 of carpet

A farmer grows x acres of peas and y acres of tomatoes. He has 12 acres available to plant peas and tomatoes. Write an inequality in x and y to satisfy this condition. The number acres of tomatoes planted must not be more then twice the number of acres of peas planted. Write an inequality in x and y to satisfy this condition.
Answers
Answer:
Y < 2X
Step-by-step explanation:
Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"
It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted
Thus, [tex]Y < 2X[/tex]
[tex]X + Y = 12[/tex] acres
[tex]Y = 12-X[/tex] acres
Thus,
[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]
Let us take X = 6 , Then Y = 13-6 = 6

What is the Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².
Given here breadth = 4 and diagonal = 8 and we know that rectangle has all four right angles
Thus, using the Pythagoras theorem we get
length = [tex]\sqrt{8^{2}-4^{2} }[/tex]
= [tex]\sqrt{64-16}[/tex]
= [tex]\sqrt{48}[/tex]
=4 [tex]\sqrt{3}[/tex]
