4- 7x = 23- 5
4 - 7x = 18
-4 = -4
-7x = 14
/-7 = /-7
X = -2
3x = -6
Answer:
A. It does not matter. The volumes of X and Y are equivalent.
Step-by-step explanation:
Volume of the pyramid = Base area × Height
For rectangular pyramid X:
Given Height of pyramid = 10cm
Base area = Length × Breadth
Base Area = 6cm×5cm = 30cm²
Volume = 10×30
Volume of the pyramid = 300cm²
For pyramid Y:
Given Height = 10cm
Base area = 1/2 base×height
Base area ,= 1/2 × 7.5×8
Base area = 30cm²
Volume of the triangular pyramid = 10×30 = 300cm³
We can see that the volume of X and Y is the same, therefore the type of chocolate Jeremy chose doesn't matter.
Remember
|x|≥0 for every real value of x
so
|x|/-6=12
divide both sideds by -6
|x|=-2
false, the absolut value cannot be negatve
