Answer:
Not accurate
Step-by-step explanation:
3+9+9=21
<span>multiply the first equation by 5 and 2nd by -7 and you get
35x-30y=-5
-35x+28y=-7
now you can cancel out the x's and you get
-2y=-12
so
y=6
now you can just plug y=6 into one of the original equations and you will see that x turns out to be 5
Hope thats okay</span>
X = 0
X=- 3 1/3 or x= -3.3
-4 1/8 as decimal.
The decimal is -3.875.
well im guessing it the average highway speed 60 mph so it is $7
