Answer:
Step-by-step explanation:
If we know that D is the midpoint, then 2x + 7 = 4(x-3). Doing the algebra on that gives us
2x + 7 = 4x - 12 and
19 = 2x so
x = 9.5
To calculate the midpoint,here's the formula : ((x1+x2)/2 , (y1+y2)/2)
thus, we have:
((10+(-4))/2 , (6+8)/2)
=(6/2 , 14/2)
=(3,7)
The coordinate for the midpoint is (3,7)

The answer is 652.50
450+45%
Marcus shoes: 35.99(5.5%)= (about) $1.98(tax) so 35.99+1.98= 37.97
Tia shoes: 39.99(9%)= (about)3.60 (tax) so 39.99+3.60=43.59
However it’s 15% off so 43.59(15%)= 6.54 so 43.59-6.54= 37.05
The difference is 0.92
