First, get the sum of the ratio. (11 + 2 = 13)
Divide 52 by 13 to find one 'part' of the ratio. (52 ÷ 13 = 4)
Now that we have one 'part' of the ratio, we multiply it by 11 and 2 to get: (£4 × 11 = £44) and (£4 × 2 = £8).
The ratio will be £44:8.
We can check if this is correct by adding 44 and 8 to see if it adds up to 52. (44 + 8 = 52). It does, so it's correct.
Y=-x-2
y=3x+2
multiply the first equation by 3: 3y=-3x-6
add up this equation with equation 2: 4y=-4, y=-1
-1=3x+2, x=-1
so the solution point is (-1,-1)
Answer:
83°
Step-by-step explanation:
A triangle adds up to 180°
180-(53+44)
The answer is C because you would move the decimal 7 places to the right to get 15,000,000.
Merchandise sold = $900
Commission = 30%
30% of $900 = 0.3 x 900 = $270
