We can do this by the tree method. What I've done here is to divide each factor by prime numbers until we have only prime numbers left. For example the second level of the tree from the top has 350 and 2. This is because 750 = 2*350. the next level has 175 and 2 because 350 = 2*175.
At the end we are left with the prime factors and find that 700 = 7*5*5*2*2
Answer:
x=3
Step-by-step explanation:
6(4x+1) = 78
Distribute
24x+6 = 78
Subtract 6 from each side
24x +6-6 =78-6
24x = 72
Divide each side by 24
24x/24 = 72/24
x =3
Answer:
52 mph
Step-by-step explanation:
1 hour is 60 minutes, 4 times the time period given in the problem. If the speed is constant, the car will travel 4 times the distance in 4 times the time.
... 4 · (13 miles) = 52 miles
The car will travel 52 miles in 1 hour, so its speed is 52 mi/h.
Answer:
$20.60
Step-by-step explanation:
You find how much it costs for the total amount of basketballs (10.40×20=208), then you subtract that number from the total cost of everything to get the cost of all the uniforms (620-208=412), then you divide the total costs for all uniforms by 20 to find the cost for a single uniform (412÷20=20.6). Always make sure that the decimals go until the hundredths place for USD.
Hope this helps!
