I hope this is helpful :)
To solve this problem, we have to find the solution for the set of equations given. This can be done as follows:
<span>y = 5x ( 1 )
12x + 9y = 60 ( 2 )
We substitute (1) to the y in (2).
</span>12x + 9(<span>5x)</span> = 60<span>
12x + 45x = 60
57x = 60
x = 60/57
y = 5(60/57) = 300/57</span>
Answer:
A
Step-by-step explanation:
PEMDAS means always do parenthesis first, which means subtract 10-6=4
To answer this problem, given the speed is 7mph and the distance is 11.2mile and its obvious that we can divide the given distance by the speed. The answer is 11.2/7= 1.6 hours
