Answer:
Bro you make no sense
Step-by-step explanation:
Answer:
15-3(3a+b)+5-6b
15 - 9a - 3b + 5 - 6b
15 - 9a - 9b + 5
20 - 9a - 9b
Step-by-step explanation:
15-3(3a+b)+5-6b
Multiple everything inside of the parenthesis by -3.
15 - 9a - 3b + 5 - 6b
Get the variables together by doing -3b-6b
15 - 9a - 9b + 5
Add 5 to 15.
20 - 9a - 9b
Final answer: 20 - 9a - 9b
The truck can cover 145 miles in 2.5 hours, so the speed of the truck is
145÷2.5=58 miles per hour
the car's speed is 1.5 times faster: 58×1.5=87 miles per hour
suppose in x hours they will meet:
distance covered by truck in x hour: 58x
distance covered by car in x hour: 87x
total distance: 145 miles
58x+87x=145
x=1
C=πr^2
Emilie d=10 so r=5
Ethan d=10/2=5 (half as long) r=2.5
Emilie c=π(5)^2=25π
Ethan c=π(2.5)^2=6.25π
6.25 is a fourth of 25 so the circumference of Ethan’s circle is a fourth of the circumference of Emily’s circle.
Answer:
$2850 is the cost of 19 tons of sugar and $6350 is the cost of trucks and sugar
