Let's plug x= -1, y= 4 in the inequation, we have:
4< 2*(-1)+5
⇒ 4< -2+5
⇒ 4< 3 (false)
Therefore, (-1,4) is not a solution of the inequation y<2x+5~
Given :
Challenge given is to volunteer for about 1 1/2 hours per week .
Autum did at a rate of 6 3/4 hours per week .
To Find :
The comparison ( ratio ) her volunteers rate with the challenge rate .
Solution :
Simplifying challenge rate in in normal fraction , .
Also , simplifying her rate , .
Now , ratio of his work by challenge is :
Therefore , the ratio is 9/2 or 4 1/2 .
Hence , this is the required solution .
The cities are 375 miles apart in real life. 10 miles in real life is 2 centimeters on the map. To find the answer to the question, divide 375 by 10 and then multiply by 2.
(375/10)×2=37.5×2
=75
They are 75 centimeters apart on the map.
A multiple is like:
Multiples of 5: 5, 10, 15, 20, 25
A factor is like:
Factors of 10:
1,2,5,10
Hope this helps!
