The dekameter (or decameter) first needs to be a translated into how many
the meters. deka means 10, so a dekameter it must be 10 meters. So we have to
divide 250 by 10, and then we will come up with 25 dekameters.
hope that helps!!
I’m cffffffdddddeddddrrddrrr
$25! Think about it, to get $15.90 as your discounted price, the unknown number must be multiplied by 60% to get $15.90. If you wanna find the original price, do the opposite! What is $15.90 divided by .6? $25!
The equation
Joy's money = 7 + 4x
Steve's money = 12 + 3x
Find the same amount of hours
Joy's money = Steve money
7 + 4x = 12 + 3x
4x - 3x = 12 - 7
x = 5
They will earn the same amount of money if they work for 5 hours.
Find how much money
money = 7 + 4x
money = 7 + 4(5)
money = 27
They get the same amount of $27
