After one hour, one guy has covered 3mi and the other 4mi, which is in total 7, not 14
After 2 hours, one guy has covered 6mi and the other 8mi, which is 14mi
The algebraic way would be:
3x +4x = 14 *x being the hour
7x = 14
x =2
Answer:
y=-1.5x-4
Step-by-step explanation:
Slope intercept form is y=mx+b
Bring x over to the other side
2y=-8-3x
divide by 2
y=-4-1.5x
y=-1.5x-4 should be your equation in slope-intercept form

Answer:
$37.85
Step-by-step explanation:
Here the price is $34.98 and there's an 8.2% tax on that. To obtain the after-tax amount due, multiply $34.98 by (1 + 0.082), or 1.082, obtaining:
1.082($34.98) = $37.85 (rounded to the nearest cent)
