Value of x: 2.5
Value of y: -0.5
-------------------------
To find x:
x + 1 = 3x - 4
-x -x
1 = 2x - 4
+4 +4
5 = 2x
-- ---
2 2
2.5 = x
Check:
2.5 + 1 = 3(2.5) - 4
3.5 = 7.5 - 4
3.5 = 3.5
To find y:
3y = 5y + 1
-5y -5y
-2y = 1
--- ----
-2 -2
y = -0.5
Check:
3(-0.5) = 5(-0.5) + 1
-1.5 = -2.5 + 1
-1.5 = -1.5
Answer: 8^2 18^2
Step-by-step explanation: The way that you figure out the power is by multiplying the 4x2=8 than the 9x2=18 than you raise them both to the second power.
The volume of the rectangular chocolate bar is 130 cm³.
<h3 /><h3>How to find the volume of rectangular prism?</h3>
volume of the rectangular chocolate prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 0.65 m = 65 cm
h = 2 cm
w = 1 cm
Hence,
volume = 65 × 2 × 1
volume of the chocolate bar = 130 cm³
