Solve for x in X-2 (x=8)
Substitute X=8 into 3x - 6y =18 (24-6y=18)
Solve for y in 24-6y=18 (y=1)
X=8 and y=1
Answer:
The answer is C
Step-by-step explanation:
There are 3 y's and there are three z's
3(y+z) means that you are multiplying 3 and y, and 3 and z which gives you 3y+3y
Which also equals y+y+y+3z
Answer:
- 15t + 5c = b
- $275
Step-by-step explanation:
Let "t' be the number of t-shirts bought.
Let "c" be the number of CDs bought.
Let b" be the total cost.
15t + 5c = b
We buy 10 t-shirts so t = 10.
We buy 25 CDs so c = 25.
We are trying to find b.
15t + 5c = b
15(10) + 5(25) = b
150 + 125 = b
275 = b
Best of Luck!
