Answer: 1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4
2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4
Speed = distance / time
<span>Speed = 400 / 253 </span>
<span>Speed = 1.58 m/s approx</span>
It will be A² + B² = C²
So 3²+5² is 34
And the square root of 34 is about 5.83
3² + 5² ≈ 5.83²
Hope that helps :)
One mile<span> is a greater measurement because it is equal to 1.6 </span>kilometers. Lets put one mile and one km into km.One <span>km is one km while one <span>mile is 1.6 <span>km.So that can also be seen as miles being a greater measurement.</span></span></span>
Answer:
