3servings=2garms
6servings=xgrams
easy way is
3 imes 2=6 so
2 times 2=4
answer is 4 grams
the ratio and proportion way
3:2=6:x
3/2=6/x
3x=12
x=4
4 grams
now convert to miligrams
1gram=1000 milgram
4 grams=4000 miligram
answer is 4000 miligrams
So 3 bus tickets 3(64) = $192
and 4 train tickets 4(82) =$328
add them together 192+328 =520
it would cost $520 to buy 3 bus tickets and 4 train tickets
Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is thatnumber times itself. The perfect squares are the squares of the wholenumbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.
To get the solution of a set of equations means to get a point that satisfies both equations.
Part (1):The first line has a rate of change of 7, this means that slope of first line is 7
The second line has a rate of change of -7, this means that slope of second line is -7
Since the slope of the first line = - slope of the second line, then these two lines are definitely perpendicular to each other.
Two perpendicular lines will meet only in one point. This means that one point only will satisfy both equations (check the image showing perpendicular lines attached below)
Therefore, only one solution exists in this casePart (2): The first given equation is:
2x + 3y = 5.5
The second given equation is:
4x + 6y = 11
If we simplified the second equation we will get: 2x + 3y = 5.5 which is exactly similar to the first equation.
This means that the two given equations represent the same line.
Therefore, we have infinite number of solutionsPart (3):We are given that the two lines are parallel. This means that the two lines are moving the same path side by side. Two parallel lines can never intersect. This means that no point can satisfy both equations (check the image showing parallel lines attached below).
Therefore, we have no solutions for this case.
The inequality is < so 2/4 < 5/6.
