Answer:
6 grapples
Step-by-step explanation:
x = number of wins
y = number of ties
y = 15 - x
48 = 5x + 2y
48 = 5x + 2(15 - x)
48 = 5x + 30 - 2x
48 = 3x + 30
18 = 3x
x = 6
The number of grapples that Jeremy win will be 6.
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
Sensei's Judo Club has a competition for the students.
Let x be the number of wins and y be the number of ties.
If you win a grappling match, you are awarded 5 points.
Then the equation will be
x + y = 15
y = 15 - x
If you tie, you are awarded 2 points.
Jeremy grappled 15 times and his score was 48 points.
Then the equation will be
5x + 2y = 48
Put the value of y in the above equation. Then we have
5x + 2(15 - x) = 48
5x + 30 - 2x = 48
3x = 18
x = 6
The number of grapples that Jeremy win will be 6.
