Answer:
The answer is $33.6
Step-by-step explanation:
Each small package costs him $2.80
3 small packages will cost him 3 x $2.80 = $8.4
Each large package costs him $3.60
7 large packages will cost 7 x $3.60 = $25.2
Cost to send 3 small packages and 7 large packages = $8.4 + $25.2
= $33.6
Answer:
2/3 already simplified
Step-by-step explanation:
Recall your d = rt, distance = rate * time
thus

notice, the first car leaves at "x" time, the other leaves on hour later, or x + 1
the first car travels some distance "d", whatever that is, thus
the second car, picks up the slack, or the difference, they're 380 miles
apart, thus the difference is 380-d
Answer:
D) x=9
Step-by-step explanation:
x = 2y- 5
2y = x + 5
y = (x+5) / 2
4x + 7(x+5)/2 = 85
8x + 7x + 35 = 85*2
15x + 35 = 170
15x = 170 - 35 = 135
x = 135/15 = 9
