Answer:

first group = 33

second = 15

Step-by-step explanation:

Let size of second group = x

size of the first group = 3x - 12

x + 3x - 12 = 48

4x - 12 = 48

collect like terms

4x = 48 + 12

4x = 60

x = 15

Substitute for x in the equation for size of the first group

3(15) - 12 = 33

Step-by-step explanation:

Area: 4πr² = 100π

r² = 25

r = 5

Volume = 4/3 * π * 5³ = 500/3 π = 166 2/3π

Solve for x.<br> .<br> Simplify your answer as much as possible.
Nady [450]

2x = 15 - 3x -- add 3x to both sides

5x = 15 -- divide both sides by 5

x = 3 -- simplest form

For the first box on the left hand side, the answer is m < 1 + m < 2 = 180 as they are a linear pair

The first box in the right-hand column is "linear pair postulate" as its very similar to the previous line

The second box on the left-hand side is m < 1 + m < 2 = m < 2 + m < 3. Essentially we're doing replacements. Similar to how x+3 = 10 turns into 7+3 = 10 when we plug in x = 7

The second box on the right-hand side is "subtraction property of equality". We subtract "m < 2" from both sides to end up with m < 1 = m < 3
