Answer:
x=31
y=6
Step-by-step explanation:
2x+3y=80
x+y=37
solve by elimination:( multiply second equation by 2) to eliminate x
2x+3y=80
2x+2y=74
subtract the two equations:
2x+3y-(3x+2y)=80-74
2x+3y-3x-2y=6
y=6 (3 point basket)
substitute: x+y=37, x=37-6=31
x=31 (2 point shot)
Answer:
d and e
Step-by-step explanation:
IV must have a pos x value and a negative y value
we can eliminate everything except d e & f
f is wrong bc it has a positive 3 value
Hello,
<span>
Let's
x pairs of women’s shoes sold
</span>y<span> pairs of men’s shoes sold
R(x,y)=45*x+50y=2500 (each week)
Or the week, =0 =>50*y=2500=>y=500.
</span>
Selling Price = $145
Charge on first $25 is 5.25%
5.25% of $25 =

Charge on rest is 3.25%
rest amount = $145 - $25 = $120
3.25% of $120 =

The expression (2/7)x (1.4x² - 3.5y) can be written in the form of a polynomial as 0.4x³ - xy.
<h3>What is polynomial?</h3>
Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
