Melissa is represented by variable m.
Josh is represented by variable j.
Chau is represented by variable c.
m+j+c= 148
c=4m
j=m+10
Substitute for c and j for the first equation.
m+(m+10)+4m=148
6m+10=148
6m=138
m=23
Plug the known m value in
j=23+10
j=33
c=4(23)
c=92
Final answer: Melissa=23 messages, Josh=33 messages, Chau=92 messages
<h2>
Answer:</h2>
7.5cm2
<h2>
Step-by-step explanation:</h2>
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Linear because x moves up by 3 and y moves up by 7
The answer is two an a half litres
To calculate 65 of 440, we solve the problem by using the following formula: (X*Y)/100 where X=65 and Y=440.
Thus, when we enter 65 and 440 into our formula, we get this:
(65*440)/100 = answer
First we multiplied 65 by 440 and then we divided that by 100. When we did this, we found the answer to be 286.
Therefore, 65 percent of 440 is 286.
