Correct answer: 231.04pi or 725.47
Answer:
$132
Step-by-step explanation:
1) In this system of eqn x represents the price of washing cars and y represents the price of washing SUVs
2) From the given eqn,
y = (84 - 4x)/2
and
y = (126 - 3x)/5
equating both the equation,
(84 - 4x)/2 = (126 - 3x)/5
=> 210 - 10x = 126 - 3x
=> 7x = 84
=> x = 12
=> y = (84 - 48)/2 = 18
Hence the co-ordinate of intersection will be (12,18)
3) The total cost of 1 car and 1 suv = x + y = 12 + 18 = $ 30
4) The total earning of hour 3
= 5x + 4y
= 5.12 + 4.18
= 60 + 72
= $ 132
So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.
x+109+x+89=180
add the numbers and x's together
2x+198=180
subtract 198 from each side
2x = -18
divide each side by 2
x = -9
Put -9 in for x in the equation x+89 to find that angle
-9+89
=80
ANSWER:
That angle equals 80°
No, in order to do the correct ratio she would have needed to add 4.5 pints to 3 pints because if you divide 9:6 by 2 it is 4.5:3 not 4:3
The answer is
15m^2n + 4/n
