X = 2y + 7 ...............(1)
2x + 2y = 200 ........(2)
Substituting the expression for x in equation (1) into equation (2) gives
2(2y + 7) + 2y = 200 .....(3)
Equation (3) simplifies to
6y = 186
Therefore y = 31 feet.
Substituting the value for y into (1) gives
x = 69 feet.
Answer:
x = -30
Step-by-step explanation:
1) x/2 = 4 - 19
2) x/2 = -15
3) x = -15*2
4) x = -30
Answer:
36π in^2
Step-by-step explanation:
Area of a circle = π(6)^2 = 36π
Answer:
<h2>The height is 10 m</h2>
Step-by-step explanation:
Area of a trapezoid is given by
<h3>
</h3>
where
a and b are the bases
h is the height
From the question
A = 135 m²
a = 20m
b = 7 m
Substitute the values into the above formula and solve for the height
That's
<h3>
</h3>
<u>Divide both sides by 27</u>
That's
<h3>
</h3>
We have the final answer as
<h3>10 m</h3>

F - Irrational, -13.8
Because the negative sign is not inside of the radical, we can tell that the number is being multiplied by the negative. Thus, do the radical equation first, get the answer 13.8202... and multiply by -1 to get the answer. Also, it is irrational because it is not a perfect square.
