Answer:
$3.75
Step-by-step explanation:
dimes= x
quarters= x+2
nickels= 2x+2
sum is 3.75
.10x+.25(x+2)+0.05(2x+2)=3.75
.10x+.25x+.50+0.10x+0.10=3.75
0.45x=3.15
x=7 dimes (0.70)
x+2=9 quarters (2.25)
2x+2=16 nickels (0.80)
They add to $3.75
Answer:
The equation: 2 + 1.75m < 35
Solution: m < 10
Shannon can travel 10 miles or less
Step-by-step explanation:
You add the initial $2 fee plus $1.75 per mile. Since she wants to pay less than 35, the inequality is 2 + 1.75m < 35.
Answer:
61.2 mph
Step-by-step explanation:
Let's first calculate the individual legs of Adara's trip in terms of both time and distance:
<u>Ashdown to Bridgeton</u>
3 hr at 60 mph = 180 miles in 3 hours
<u>Bridgeton to Carton</u>
30 miles at 70 mph: 30 miles/(70 miles/hour) = 0.429 hours
<u>Total Trip</u>
Miles = 180 + 30 = 210 miles
Time = 3 + 0.429 = 3.429 hours
Average speed is (210 miles)/(3.429 hours) = 61.25 or 61.2 miles/hour to 1 decimal point.
Answer:
y =5/3x - 8
Step-by-step explanation:
5x - 3y = 24
-3y = -5x + 24
y = 5/3x - 8
