Juan has $20 and Julio has $40
Answer:
Age Group Number of People 18–24 80 25–31 120 32–38 40 39–45 20
Step-by-step explanation:
The data in each bar is how many people in that group.
So 18-24 has 80 people
25-31 has 120 people
32 -38 has 40 people
39-45 has 20 people
Answer:
$13.67
Step-by-step explanation:
Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:
i. 4c + 4d= 164
The cost of the 4 CDs is half the cost of the 4 DVDs, to put into an equation it will be:
ii. 4c= 0.5(4d)
4c= 2d
d= 2c
Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:
4c + 4d= 164
4c + 4(2c)= 164
4c+ 8c= 164
12c= 164
c=13.67
The cost for each CD is $13.67
q + 20 = p
Since the number p is 20 more than the number q, you would put it in an equation to identify the relationship between these numbers. 20 plus q makes p.
In this question , it is given that, Perimeter of a rectangular room is 270 yards. Longer side of the room is 15 yards longer than the shorter side.
So if we let shorter side be x, then longer side is
And perimeter is equal to sum of all sides, that is
So the smaller side is 60 yards , and longer side is 15 more then 60 that is 75 yards .
