Although the student in the example used in this question did not make
too many errors, there is a better way of working out this equation so
that you will find the correct answer. In an equation like this where
you need to get I on it's own, you need to divide everything by two to
get -w+P over 2 = l. To get to this point, to start with you would need
to do -2w+P=2l instead of P-2w=2l.
X= total acres on farm
x * 21%= 168
move decimal 2 places to the left to go from percent to decimal form
x * 0.21= 168
divide both sides by 0.21
x= 800 acres
ANSWER: There are a total of 800 acres on the farm
Hope this helps! :)
Answer: (2,8)
Step-by-step explanation:
The origin is the point (0,0), so when you move two units right you land on the x-value of 2. From there you then add 8 units, putting you at the y-value of 8. Therefore, you end with the point (2,8) after this translation.
Answer: X=8
Since it has a right angle and you have 2 sides.
The system of linear equations represents the situation is;
x + y = 125
x + y = 1255x + 8y = 775
<h3>Simultaneous equation</h3>
Simultaneous equation is an equation in two unknown values are being solved for at the same time.
let
- number of quick washes = x
- number of premium washes = y
x + y = 125
5x + 8y = 775
From equation (1)
x = 125 - y
5x + 8y = 775
5(125 - y) + 8y = 775
625 - 5y + 8y = 775
- 5y + 8y = 775 - 625
3y = 150
y = 150/3
y = 50
x + y = 125
x + 50 = 125
x = 125 - 50
x = 75
Therefore, the number of quick washes and premium washes Monica’s school band had is 75 and 50 respectively.
