2(3y+10)=38
6y+20=38
6y=18
y=3
Put this into a scientific calculator
1/3 x pi x 18 squared x 16
Answer:
x = 3 or y = -3
Step-by-step explanation:
To find x, substitute y with a 0.
0=x-3. Minus the x on both sides and x will equal 3
To find y, substitute x with a 0.
y=0-3. 0-3 equals -3 which means that y will equal -3
Answer:
0.6
Step-by-step explanation:
subtract 4.5 from 3.9
Cost of Case of Juice: 20
Cost of Case of Water: 15
What is an equation?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
Here, we let
cost of a case of juice = x
cost of a case of water = y
6x + 1y = 135...(1)
4x + 2y = 110.....(2)
Now, we multiply equation (1) by 2 and equation (2) by 1 and we get
12x + 2y = 270
4x + 2y = 110
Now, we subtract equation (1) from equation (2) and we get
8x = 160
x = 20
and y = 15
Hence, the Cost of a Case of Juice: 20
Cost of Case of Water: 15
