So we are finding the difference btween 5x-3 and 3x+1.
(5x-3)-(3x+1)
Let's subtract the x's first.
5x-3x=2x
Now the numbers.
-3-1=-4
Now, we need to put 2x and -4 together.
The expression would be 2x-4.
1/5 - 5/6 = -19/30, so the answer is Y ≤ 19/30

Answer:
Question 1- 288.48
Step-by-step explanation:
depending on how they round your answer the number might look different.
V= Bh which means (pi)r^2(h)
3.14 x 1.25^2 x 4.9
V=24.040625 ~ 24.04
12 x 24.04
=288.48
Answer: 225
Step-by-step explanation:
Volume of the pyramid is calculated as 1/3 bh, where b is base and h is height
Given height as 39cm and a base of 10√3cm = 10 x √3, where √3= 1.73; base = 10 x 1.73 = 17.3
Slot the values into the formula:
Volume = 1/3 × 17.3 x 39
= 1/3 × 674.7 = 674.7/3
Volume = 224.9 approximately 225.
I hope this helps.
