Answer:
103
Step-by-step explanation:
your friend's score=x
twice your friend's score=2*x
then your score=6+2*x
Given that your score is=212
In other words, 6+2*x=212
2*x=212-6
2*x=206
x=206/3
x=103

Answer:
Your answer is 62 square inches
Step-by-step explanation:
You can cross off 1 & 2, as they are too small.
Lets split this up.
(2*3)+(2*3)+(3*5)+(3*5)+(2*5)+(2*5)
2*3 + 2*3 = 12
3*5 + 3*5 = 30
2*5 + 2*5 = 20
30+20+12 = 62
Answer:
Car = 10 miles/hour
Bus = 20 miles/hour
Step-by-step explanation:
Here,
Let, the value of the speed of the bus = X
the value of the speed of the car = 2X - 30 (As the speed of the car is 30mph slower than twice)
According to the question,
2X - 20 = 2*(2x-30)
or, 2X - 20 = 4X-60
or, 2X = 40
x = 20
Therefore, the speed of the bus, x = 20 miles/hour
So, the speed of the car is (2*20-30) mph = (40 - 30) mph = 10 miles/hour.
