Answer:
x=1, y=6. (1, 6).
Step-by-step explanation:
-8x+4y=16
y=5x+1
----------------
-8x+4(5x+1)=16
-8x+20x+4=16
12x+4=16
12x=16-4
12x=12
x=12/12
x=1
y=5(1)+1=5+1=6
We can see from this survey that 7 teenagers prefer rock and roll.
The number of all teenagers in the survey is:
12 + 5 + 7 + 6 + 6 + 4 = 40
P ( rock ) = 7 / 40
Answer: C ) 7 / 40
Answer:
<h3>
D. 5 x 10⁶ ÷ 6.6 x 10⁴</h3>
Step-by-step explanation:
If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;
6.6 x 10^4 mi² = $5 X 10^6
1mi² = $x
Cross multiply;
$5 X 10^6 * 1 = 6.6 x 10^4 * x
6.6 x 10⁴ x = 5 X 10⁶
Divide both sides by 6.6 x 10⁴ to get x;
6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴
x = 5 x 10⁶ ÷ 6.6 x 10⁴
x = 0.76*10⁶⁻⁴
<em>x = $0.76*10²</em>
<em />
Hence the key strokes on a calculator will give the cost the United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴
