Answer: plane A = 333.33mph
Plane B = 500mph
Step-by-step explanation:
Given data:
Distance between the two planes = 2400miles.
Plane A flew North
Plane B flew south
Solution:
Let v represent plane A.
Let 2v represent plane B.
Distance between the two plane
v + 1.5* v = 3*v
7.5v = 2500miles
v = 333.33mph
Plane B has one and half times the speed of plane A
= 1.5 * 333.33
= 500mph
-5.8 - (-8.4)
When we multiply two negatives they become a positive. In this situation, where there is no other number, you can assume there's basically a 1 in that place.
-5.8 - 1(-8.4) would be just as correct. (If this helps visually clarify anything.)
So we take that -1 and multiply it by that -8.4. Multiplying 1 against anything leaves it the same, so we just need to change the sign. Two negatives make a positive.
-5.8 + 8.4
Now we add these together.
This gives us our final answer of 2.6
Answer:
38 metros
Step-by-step explanation:
Número total de metros que Juan quiere pintar su casa = 200 m
Durante los primeros 2 días, pintó = 33 m todos los días
Por lo tanto, el número total de metros que pintó = 33 m × 2 = 66 m
Al tercer día, practica la pintura = 96 m
El número de metros que quedan por pintar se calcula como:
200m - (66m + 96m)
Los 200m - 162m
= 38m
