The answer is 300,000 because you have to round the bigger number that is 2 and don't forget to go next door and round 7 and that tell if it going up one more. We round 277,300 7 is more so add one more to the 2 and that is 300,000.

<em>Answer:</em>
<em>A proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps:
</em>
<em>
</em>
<em>200 miles ... 5 inches
</em>
<em>50 miles ... x inch = ?
</em>
<em>
</em>
<em>200 * x = 5 * 50
</em>
<em>x = 5 * 50 / 200
</em>
<em>x = 1.25 inch
</em>
<em>
</em>
<em>The correct result would be x = 5 * 50 / 200.</em>
Answer:
xy = 1
k = 79
Step-by-step explanation:
Question One
The first and third frames look to me to be the same. I'll treat them that way.
y = x^2 Equate y = x^2 to the result of 2y + 6 = 2x + 6
2y + 6 = 2(x + 3) Remove the brackets
2y + 6 = 2x + 6 Subtract 6 from both sides
2y = 2x Divide by 2
y = x
Now solve these two equations.
so x^2 = x
x > 0
1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is
x(x) = x Divide both sides by x
x = 1
y = x^2 Put x = 1 into x^2
y = 1^2 Solve
y = 1
The second solution is
(1,1)
xy = 1*1
xy = 1
Answer: A
Question Two
square root(k + 2) - x = 0
Subtract x from both sides
sqrt(k + 2) = x Square both sides
k + 2 = x^2 Let x = 9
k + 2 = 9^2 Square 9
k + 2 = 81
k = 81 - 2
k = 79
