Answer: 53
Step-by-step explanation:Divide 159/3 to get the rate per second
Let these two numbers be 
and 
. Their sum is 
, their difference is -4, and their product is -29:
Add the first two equations together to eliminate :
Then
Just to confirm this is correct, check their product:
Answer:
45 miles
Step-by-step explanation:
40 minutes = 30 miles
1 minute = 30÷40 => 0.75 miles
60 minutes = 0.75×60=> 45 miles
First work out (5/2)³ by cubing both the numerator and denominator to give: 125/8
then work out (3/4)² by squaring both the numerator and denominator to give: 9/16
then divide 125/8 by 9/16
using the stay-change-flip method of division:
the first term stays the same, the divide becomes multiply and the second fraction is flipped upside down.
so:
125/8 x 16/9 =2000/72
then just divide 2000 by 72 to give: 27.78 to 2 d.p
therefore the greatest whole number than 27.78 is 27.
Answer:
Indirect method actually follows the same set of procedure as the direct method except that it begins with net income unlike the elimination method reduced a given system that indicates a system has no unique solution.
