Answer:
8b+7p=20
p = 2b
Step-by-step explanation:
Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance
Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance
So the total distance would be
= 8b + 7p
And, the total km is 20
Now the whole equation would be
8b + 7p = 20
Also it is mentoined that for getting into the park it is twice for getting into the beach
So, it would be
p = 2b
Therefore the system of equations are as follows
8b+7p=20
p = 2b
Answer:
2.46×10^8
Step-by-step explanation:
The decimal point is here
246000000.
Then it must be moved up to here
2.46000000
Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8
Then you have
2.46×10^8
Answer:
10 yards and 4 feet
Step-by-step explanation: multiply 5x2 then 2x2
Answer: -9
Step-by-step explanation:
Divide 63 by -7 and you get -9
Hope this helps :)
It should be C
Because when u multiply ( -3)*(x-4y= -8)
It’ll equal to -3x+12y=24 which is the same equation to the other one.
When the equations r the same, it means everything on the line is the solution for this system of equation.
