$1250
Answer:
The correct answer is (D).
.
Step-by-step explanation:
The 5 houses in both Oakcrest and 1980s category should not be counted twice. The correct probability is 105/220.
Subtract 4/7 on both sides to get b=-4/7-3. Then simplify.

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
29° + (4x + 9)° + (x + 17)° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 5x + 55 = 180
- Isolate <em>x</em> term: 5x = 125
- Isolate <em>x</em>: x = 25
Answer:
x = 5 ± sqrt(35)
Step-by-step explanation:
X^2 - 10x+ 25 = 35.
Factor the left hand side. This is the difference of squares. a^2 -2ab - b^2 = (a-b)^2 where a = x and b = 5
(x-5) ^2 = 35
Take the square root of each side
sqrt((x-5) ^2) =± sqrt(35)
x-5 = ± sqrt(35)
Add 5 to each side
x-5+5 = 5 ± sqrt(35)
x = 5 ± sqrt(35)
