Answer:
4,000,000,000 meters
Step-by-step explanation:
4 x 10,000,000,000,000 x 0.0001 = 4,000,000,000 meters
A. The area of the paralelogram is base • height so is (4x-2)•(2x-1)= 8x^2. -8x+2
b. X=2
A= 8•4-8•2+2= 32-16+2= 14 in^2
7/8 of an hour is 52.5 minutes. 3/10 of 52.5 minutes is 15.75 minutes. They spent 15.75 minutes warming up and cooling down.
Decimals are no fun. It might be a good idea to get rid of the decimals as a first step.
Notice that the smallest decimal value is in the THOUSANDTHS PLACE. So if we multiply both sides by 1000, that should do the trick.
1000( 0.007x + 0.03 ) = 1000( 0.1 )
With each term, we'll move the decimal 3 places.
That's what it means to multiply by 1000.
7x + 30 = 100
From that point the problem becomes quite a bit easier.
Subtract 30,
7x = 70
Divide by 7 as a final step,
x = 10
Hope that helps :)
