W= 31.4
Step 1: 4*Pi = 12.566370614359
Step 2: -6*Pi = -18.849555921539
Step 3: Rewrite equation (12.566370614359=w-18.849555921539)
Step 4: Move the number that is equivalent to 6Pi over to the other side of the equal sign to get the variable alone. (12.566370614359+18.849555921539 = 31.415926535898 ) The problem should now look like this, <span>31.415926535898=w
Step 5: Divide the numbers (which you don't really need to do here since the "number" in front of w is 1. This is helpful to know for future problems though.)
Step 6: Round to the nearest tenths place (or however you need to) giving you the final answer of 31.4 </span>
Answer:
13 and 44
Step-by-step explanation:
let x and y be the 2 numbers with y < x , then
x - y = 31 ( add y to both sides )
x = y + 31 ( subtract 31 from both sides )
x - 31 = y → (1)
4y = x + 8 → (2)
substitute y = x - 31 into (2)
4(x - 31) = x + 8
4x - 124 = x + 8 ( subtract x from both sides )
3x - 124 = 8 ( add 124 to both sides )
3x = 132 ( divide both sides by 3 )
x = 44
substitute x = 44 into (1)
44 - 31 = y , then
y = 13
the 2 numbers are 13 and 44
Answer:
£3.66
Step-by-step explanation: if you need it :D
17 + 23 = 40
40 = 16 what about 17
16 × 17 = 272 ÷ 40 = £6.8
16 - 6.8 = £9.2
20% of £6.8 = £1.36
1/4 of £9.2 = £2.3
1.36 + 2.3 = £3.66
Can you mark my answer brainliest? Tysm! :D

Answer:
x = 21
Step-by-step explanation:
Given
5(3x - 9) = 2(6x + 9) ← distribute parenthesis on both sides
15x - 45 = 12x + 18 ( subtract 12x from both sides )
3x - 45 = 18 ( add 45 to both sides )
3x = 63 ( divide both sides by 3 )
x = 21
