Answer:
915
Step-by-step explanation:
V=l*w*h V=1/2*b*h*l
V of the rectangular block: 15*5*8 = 600
V of the triangular prism--it's easiest to solve half of it, then just multiply that answer by 2: 1/2*5*7*9 = 157.5
When you double it, it cancels out the 1/2
157.5*2=315
315+600=915
Answer:
x=5
y=3
Step-by-step explanation:
7x=35
x= 5
3 x 5 - y= 12
15-y = 12
y= 15 - 12
y= 3
so , 5, 3
hope it helps !
Answer:
The system is of equations is:

Where g is the amount of general tickets and r is the amount of reserve tickets.
35 general tickets and 25 reserve tickets were sold.
Step-by-step explanation:
Let general tickets be represented by g and reserved tickets be represented by r.
Each general ticket sells for $10 each and reserved tickets $15 each. Dave collected a total of $725. Thus:

And a total of 60 tickets were sold. Hence:

Our system of equations is:

We can solve by substitution. First, divide both sides of the first equation by 5:

Next, we can subtract a variable (r in this case) from the second equation:

Substitute:

Distribute:

Simplify:

Subtract:

Using the previous equation:

Substitute and evaluate:

So, 35 general tickets and 25 reserve tickets were sold.
