Step-by-step explanation: 13.93 + 7.37 = 21.3 14 + 7 = 21
Answer: 150, 80
Step-by-step explanation:
Let's represent how far Eli travels as x.
Sara travels twice as far as that, so 2x.
Ashley travels as far as Eli and Sara combined. x + 2x = 3x.
Hazel travels 3× as far as Sara, and 3×2x = 6x.
All of these add up to 888.
x + 2x + 3x + 6x = 888
Let's add up these like terms.
12x = 888
We can then divide each side by 12...
x = 74
Therefore, Eli traveled 74 miles!
We can use this value to figure out everyone else's distances as well.
Sara = 2 × 74 = 148
Ashley = 3 × 74 = 222
Hazel = 6 × 74 = 444
You can only draw one line containing three collinear points. Indeed, for any two distinct points, there's only one line that passes through both points.
<span>Of course, there are countless different ways to write the equation of such a line, but if you graph them (or algebraically manipulate the equations), they all turn out to be the same line.</span>
