Sean and his family are picking strawberries at a pick-your-own fruit farm. The rectangular strawberry field has an area of 210,

nasty-shy [4]

Answer:

512 ft is the length of the field

Step-by-step explanation:

Firstly, we need to know the area of the field. We have confirmed this to be rectangular. Since it’s a rectangular field, the area of the field can be obtained by multiplying the length of the field by the breadth or width of the field.

Mathematically A = L * W

In the question, A = 210,944 ft^2

L= ? and W = 412ft

In essence, we are trying to calculate the value for the length of the field

L = A/W

L = (210,944)/412 = 512ft

(x+3)^2 = x^2-3(1-x)

Oxana [17]

(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4

Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)

Volunteers were 3/4 finished with the walkathon when they reached the 4 1/2 kilometer mark. How many kilometers was the walkatho

den301095 [7]

5 I think, cause if your 3/4 ways done you need to walk 1/2 more kilometers to be finished... So if you add 1/2 to 41/2 it equals 5

Use substitution to solve the system. 5X+3Y=22 Y=2X-11

Ad libitum [116K]

Answer:

See below:

Step-by-step explanation:

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.

We can solve this problem in two steps, Comprehending, and Solving/Checking our answers. I'll be starting off with Comprehending.

Comprehending

We can solve the problem with substitution by finding out what one variable is equal to in terms of the second variable.

This is what we would call System of Equations where we need to find the point where the lines hit.

We can do this either with Graphing, or Algebra. In this case, we need to use substitution, so it has to be Algebraically.

Now that we know how to solve it/what to do, we can start solving.

Solving

We can solve the problem by first replacing y with its correct value in terms of x. Since we know the two equations, we can begin solving.

$y=2x-11\\5x+3y=22$

We can solve it by inserting our y value into the y value of the second equation.

$5x+3(2x-11)=22\\5x+6x-33=22\\11x=22+33\\11x=55\\x=5$

Now that we know our x value, we can solve for y by inserting it into an equation.

$y=2(5)-11\\y=10-11\\y=-1$

Now that we have solved, we have gotten out point of (5,-1)

We can test this by inputting it into an equation. (Any of the latter).

$5(5)+3(-1)=22?\\25-3=22?\\22=22$

Now that we have checked our answer and it appears correct, we have gotten our answer of (5,-1).
