Answer:
The number of Girls players in the Team of 18 players is 6 .
Step-by-step explanation:
Given as :
The total number of player including boys and girls = 18
And times girls player + times boys player = 7
Let The number of boys player = B
The number of girls player = G
So, According to question
G + B = 18 ...1
× G + × B= 7
or, + = 7 ...2
or, Put the value of B from eq 1
or, + = 7
Or, - + 6 = 7
or, = 7 - 6
Or, = 1
∴ G = 1 × 6 = 6
Hence The number of Girls players in the Team of 18 players is 6 . Answer

Answer:
1/3x - 6
Step-by-step explanation:
Perpendicular lines have the negative reciprocal slope. This means that you find the slope of the original line which is -3. Then you flip it so it’s -1/3. Lastly you change the sign 1/3. The negative 6 is the y intercept the question asked for.
An equation is formed when two equal expressions. The cost per pound of wheat flour is $0.55 and the cost of per pound of rye flour is $0.55.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the cost of a pound of wheat flour be x and the cost of a pound of rye flour be y.
A baker purchased 13 lb of wheat flour and 14 lb of rye flour for a total cost of $14.85.
13x + 14y = $14.85
x = (14.85-14y)/13
A second purchase, at the same prices, included 15 lb of wheat flour and 12 lb of rye flour.
15x + 12y = $14.85
Substitute the value of x from the above equation and solve for y,
Substitute the value of y in any one of the equations formed,
13x + 14(0.55) = 14.85
13x = 7.15
x = 0.55
Hence, the cost per pound of wheat flour is $0.55 and the cost of per pound of rye flour is $0.55.
