below is 160 feet. What is the area of the
playground?
Answers
Known :
Perimeter = 160 ft
length = 50 ft
Asked :
Area = ...?
Answer :
Find the width first :
Perimeter = 2 (length + width)
160 = 2 (50 + width)
width = (160 ÷ 2) - 50
width = 80 - 50
width = 30ft
Now, let's find the Area :
Area = length × width
= 50 × 30
= 1.500ft²
So, the area of the playground is 1.500ft²
Hope it helpful and useful :)

Let's change 3/4 to .75 and multiply by 10 since we need 10 servings.
.75 x 10 = 7.5 so she would need 7.5 cups or 7 1/2 cups
Since she only has 5 1/2 cups, she does not have enough.
3x − 2y + 2z = 2

Answers
Answer:
No solutions
Step-by-step explanation:
We need to eliminate one of the variables to solve the system. To do so, let's multiply the first equation by 8, the second equation by 4
- 2x + y + 5z = 4 (1) x 8
- 3x − 2y + 2z = 2 (2) x 4
- 5x − 8y − 4z = 1 (3)
The system becomes:
- 16x + 8y + 40z = 32 (1)
- 12x - 8y + 8z = 8 (2)
- 5x - 8y - 4z = 1 (3)
Add (1) and (2), subtract (3) from (2) to eliminate y
- 28x + 48z = 40 (4)
- 7x + 12z = 7 (5)
Then multiply the equation (5) by 4 to compare with(4)
- 28x + 48z = 28
Comparing the equations (4) and (5) we see it has no solutions as both variables have same coefficient but with different sum, 28≠40

Answer:
c = -a - b + 180
Step-by-step explanation:
Isolate the c. Note the equal sign, what you do to one side, you do to the other. Subtract a and b from both sides
a (-a) + b (-b) + c = 180 (-a) (-b)
c = 180 - a - b
c = -a - b + 180 is your answer

-- All three sides of a scalene triangle have different lengths.
So 'x' can't be 15 and it can't be 25.
-- 'x' must be 10 or more in order to reach between the ends
of the 25 and the 15.
-- 'x' must be less than 40 in order for the 25 and the 15 to reach
between its ends.
So the value of 'x' must satisfy these conditions:
0 < x < 15
15 < x < 25
25 < x < 40
Any number that satisfies these conditions is an acceptable value for 'x'.
This triangle is really flat. So much so that you could put it on a number line.
It literally cannot get any flatter, and the largest side literally cannot get any bigger.
Well, the smaller two sides would add up to equal the third.
From this we have realized something: The largest side of any triangle cannot be larger than the sum of the other two.
Let's think back to our problem.

Since it's a scalene triangle, x cannot be 15 or 25 either, so add that too.
