Answer:
The number of shots Nick sunk was 8
Step-by-step explanation:
Let
x -----> number of shots that Nick sunk.
y -----> number of shots Nick missed
we know that
x+y=28
y=28-x -----> equation A
5x-2y=0 ----> equation B
substitute equation A in equation B and solve for x
5x-2(28-x)=0
5x-56+2x=0
7x=56
x=8
Find the value of y
y=28-x ----> y=28-8=20
therefore
The number of shots Nick sunk was 8
<span>You have studied polynomials consisting of constants and/or variables combined by addition or subtraction. The variables may include exponents. The examples so far have been limited to expressions such as 5x<span>4 </span>+ 3x<span>3 </span>– 6x<span>2 </span>+ 2x containing one variable<span>, </span>but polynomials can also contain multiple variables. An example of a polynomial with two variables is 4x2y – 2xy2 + x – 7.</span>
Many formulas are polynomials <span>with more than one variable, such as the formula for the surface area of a rectangular prism: 2<span>ab </span>+ 2bc + 2ac, where <span>a, b, </span>and <span>c </span>are the lengths of the three sides. By substituting in the values of the lengths, you can determine the value of the surface area. </span>By applying the same principles for polynomials with one variable, you can evaluate or combine like terms in polynomials with more than one variable<span>.</span>

Answer:
-14x +21 = 7x -24
Step-by-step explanation:
We assume your use of the multiplication symbol in this problem (×) is intended to represent the variable x.
The distributive property tells you that the factor outside parentheses multiplies each of the terms inside parentheses:
a(b+c) = ab+ac
Your equation can be simplified as ...
-7(2x -4) -7 = 3(x -5) +4x -9 . . . . given
-7(2x) +(-7)(-4) -7 = 3x +3(-5) +4x -9 . . . . use the distributive property
-14x +28 -7 = 3x -15 +4x -9 . . . . . . . . . . . carry out the multiplication
-14x +21 = x(3+4) -(15 +9) . . . . identify and group like terms on the right*
-14x +21 = 7x -24 . . . . . . . . . . do the arithmetic

* note that the distributive property can also be used to combine terms:
3x +4x = x(3+4) = 7x
