Stephen Curry's record during the 2017 - 2018 NBA final game is made up of 2-point shots and 3-points.

grandymaker [24]

Answer:

x = 12 ( two points shots )

y = 7 ( three points shots )

Step-by-step explanation:

Let´s call "x" two points shots, and "y" three points shots, then

x + y = 19

2*x + 3*y = 45

We have to solve a two-equation system for x and y

y = 19 - x

2*x + 3 * ( 19 - x ) = 45

2*x + 57 - 3*x = 45

- x = 45 - 57

-x = - 12

x = 12

And y = 19 - 12

y = 7

If you want to add or subtract fractions :

1- make sure that the denominators of the fractions are equal. if they are not, then multiply each of them by a number so that they will be equal.

2- add or subtract the numerators.(if you already had multiplied the denominator of a fraction by a number, then you should multiply the numerator by the same number and do the adding or subtracting)

3- simplify it's possible

here are the answers :

$\frac{3}{7} + \frac{6}{11} = \frac{33 + 42}{77} = \frac{75}{77}$

$\frac{1}{3} + \frac{3}{4} = \frac{4 + 9}{12} = \frac{13}{12} = 1 \frac{1}{12}$

$\frac{4}{5} + \frac{3}{7} = \frac{28 + 15}{35} = \frac{43}{35} = 1 \frac{8}{35}$

$\frac{7}{12} - \frac{1}{8} = \frac{14 - 3}{24} = \frac{11}{24}$

$\frac{9}{10} - \frac{2}{3} = \frac{27 - 20}{30} = \frac{7}{30}$

good luck
