Answer:
The dimensions are 6 by 5 feet.
Length = 6 feet.
Width = 5 feet.
Step-by-step explanation:
Let the length = L
Let the width = W
Perimeter of a rectangle = 2L + 2W
Translating the word problem into an algebraic equation, we have;
L = 2W - 4 ........equation 1
22 = 2L + 2W .......equation 2
Substituting the value of "L" into equation 2, we have;
22 = 2(2W - 4) + 2W
22 = 4W - 8 + 2W
22 + 8 = 6W
30 = 6W
W = 30/6
Width, W = 5 feet.
To find the length, L
Substituting the value of "W" into equation 1, we have;
L = 2W - 4
L = 2(5) - 4
L = 10-4
Length, L =6 feet
Therefore, the dimensions of the garden are 6 by 5 feet.
Assuming early termination, Alice's fixed costs are $200 for the phone and $175 for the fee, for a total of $375. Her variable cost is $50 per month. Her total cost is ...
b. y = 50x + 375
Let x be the number multiplied by 7.
We get 7x.
At least 30 means GREATER THAN OR EQUAL TO 30 or ⩾ 30.
Put it all together now.
7x ⩾ 30
Divide both sides by 7.
x ⩾ 30/7
Done!
Answer:
I think the answer is 3rd, 6th, and then 10th for each statement.
Step-by-step explanation:
I'm doing this activity right now on PLATO but I haven't turned it in yet. However, I know that this is the expanded form:
(
x + y
)
^10 = 1 × x
^10 × y
^0 + 10 × x
^9 × y
^1 + 45 × x
^8 × y
^2 + 120 × x
^7 × y
^3 + 210 × x
^6 × y
^4 + 252 × x
^5 × y
^5 + 210 × x
^4 × y
^6 + 120 × x
^3 × y
^7 + 45 × x
^2 × y
^8 + 10 × x × y
^9 + 1 × x × y
^10
All you have to do is count each term.
For example, I know that the third term is 45x^8y^2 because I counted the first two and saw it was the third.
Hope his helped because I couldn't find the answer for this anywhere else!
