The bus traveled<span> at an </span>average speed<span> of </span>40 km/h<span> and </span>she<span> - 2385764. ... </span>bus<span> from </span>her home<span> to the </span>bank <span>and </span>then walked back<span> to </span>her home along<span> the </span>same route<span>. ... To determine the time, x, that it </span>took Talia<span> to</span>walk home<span>, </span>she<span> used the equation </span>40(0.9<span> – x) = 5x. 1 ... Therefore, it </span>took Talia<span> 0.8 </span>hour<span> to </span>walk home<span> or 48 minutes</span>
Multiply the first equation by -1 to get -4x - y = --5
Then add the second equation 3x + y = 3
+ ____________
-x = -2 or x = 2
then plug in 2 for x in one of the equations and solve for y 4(2) + y = 5
8 + y = 5
Subtract 8 from both sides y = -3
So x = 2, y = -3 or (2,-3)
Answer:

If 22% are sixth graders, then the rest must not sixths graders.
100% of the school - 22% sixth grades = 78% are not sixths graders
Por lo que, el valor absoluto de -9 es 9. El valor absoluto de 9 es el número de unidades que está 9 del cero. Nueve está a nueve unidades de cero.
