13 units from 20 could either be 33 or 7; 15 units from -8 could either be 7 or 23.Since 7 satisfy both of the above requirements, Sarah's favorite number is 7. (You could show your work using a number line)
The two possibilities of Neil's favorite number are 26 and -12.
Set up a proportion.100 over 140 is = to x over 100. from there you cross multiply to get 10000=140x. then you divide both sides by 140 and get 71.42857143 and round it. if you are rounding to the nearest whole # it would be 71%
Answer:
y=1 when x=5
Step-by-step explanation:
-2(5)+11=-10+11=1
Assume that the larger number is m and the smaller one is n.
the larger is 10 less than twice the smaller, this means that:
m = 2n-10
the sum of the two is 38, this means that:
m+n = 38
substitute by the first equation in the second one:
2n-10+n=38
3n=48
n= 16
substitute by n in the first equation:
m=2n-10=2(16)-10= 22
based on this,
the larger number is 22 while the smaller number is 16
