Answer:
15 km/h
Step-by-step explanation:
Leo takes 15 minutes to cycle to school at an average speed of 12 km/h. What speed will he have if he only takes 12 minutes?
15 minutes * (1 hour)/(60 minutes) = 0.25 hour
speed = distance/time
distance = speed * time
distance = 12 km/h * 0.25 hour = 3 km
He cycles a distance of 3 km.
12 minutes * (1 hour)/(60 minutes) = 0.2 hour
speed = distance/time
speed = 3 km/(0.2 hour)
speed = 15 km/h
m= 70/27 simplified m= 2 16/27
If that is a square to the parenthesis then it would be D. the formula is (x-h)^2+(y-k)^2=r^2
Answer: There are 180 grape juice in the store
Step-by-step explanation:
The ratio of containers of orange juice to containers of grape juice in a store is 5 orange juices to 4 grape juice which can be expressed as 5:4
Total number of containers = 405
total ratio = 4+5 =9
The number of containers that are orange juice = 5/9 x 405
=5 x 45=225
The number of containers that are grape juice will now be = 4/9 x 405
=4 x 45= 180.
Answer:
Answer as a decimal: 
Answer as a fraction: 
Step-by-step explanation:
y - 15 = 3x
-2x + 5y = -3
Solve the first equation first to substitute into second equation
y - 15 = 3x
Add 15 to both sides of the equation
y = 3x + 15
Substitute this value of y into second equation
-2x + 5y = -3
2x + 5(3x + 15) = -3
Multiply
2x + 15x + 75 = -3
Add the x's
17x + 75 = -3
Subtract 75 from both sides of the equation
17x = -78
Divide both sides of the equation by 17
