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
Answer:
6802
Step-by-step explanation:
just multiply 8950 x .76 (which is the 76 percent)
General Idea:
Integers in real life are used to denote both positive and negative numbers. For example to represent profit, gain, increase, deposit, Income we use positive integers and to represent loss, expenditure, decrease, withdrawal we use negative integers.
Conclusion:
The integer describes gaining 5 pounds is +5.
Answer:
55
Step-by-step explanation:
1st you would find the equation which would be (16 + 6.50x) = (10 + 7.50x) then you would find the answer which would be x = 6 then you would do 6.50 times 6 which would give u 39 add that to 16 which is 55 and do the same on the other side (7.50 times 6) which would give u 45 and then add the 10 which is 55 so the answer is 55.
Answer:
x=-8, y=76/3
