Answer:
-Noah could buy 10 tacos for $15.
-Jada's tacos were not the same price as Noah's tacos.
Step-by-step explanation:
You can use a rule of three to find the amount of tacos that Noah could buy with $15:
$6 → 4
$15 → x
x=(15*4)/6=10
At this rate, Noah could buy 10 tacos for $15.
Now, to find out if Jada's tacos were the same price as Noah's tacos, you have to find the price per taco in each case by dividing the amount paid by the number of tacos bought:
Noah: 15/10=1.5
Jada: 72/50=1.44
According to this, Jada's tacos were not the same price as Noah's tacos.
As it is, in accordance with the priorities of the operators (or the PEMDAS rule) the equation without parentheses mean
<span>(2/3)x+1=(1/6)x-7
I do not suppose you mean the above, since the solution is relatively trivial.
I suppose you actually mean
</span><span>2/(3x+1)=1/(6x-7)
in which case you would cross-multiply:
2(6x-7)=(3x-1)
and expand/distribute
12x-14=3x-1
isolate x and solve
12x-3x=-1+14
9x=13
x=13/9
If you mean the first form of equation without parentheses, my apologies.</span>
