Answer: 48.95
Step-by-step explanation:
so first I would add together the cost of the shirt and hat
31.59 +19.46 = 51. 05
then I would take away the 51.05 ( the total ) from $100
100 - 51.05 = $48.95
So she would get $48.95 for change
Easy! multiply the 6% by $8 then add it to the $8, now, multiply the 15% by the total of the cost with tax. then you all that to the total. ($9.75)
Yes. I believe so. If u solve the equations you get x=1/2 and y=-1
Answer: 4
The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given
Flip the sign to get -1/4 turn into +1/4 or just 1/4
Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.
Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.
