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)

When a student sold an Xbox on eBay for $145, she was charged a two-part final value fee: 5.25% of the first $25 of the selling
Contact [7]
Selling Price = $145

Charge on first $25 is 5.25%
5.25% of $25 = \frac{5.25}{100}*25= \frac{5.25}{4} = 1.3125

Charge on rest is 3.25%
rest amount = $145 - $25 = $120
3.25% of $120 = \frac{3.25}{100}*120=3.9

Total\ charge=1.3125+3.9=5.2125 =\boxed{5.21}

WILL GIVE BRAINLIEST<br><br><br> Write 2/7x(1.4x^2-3.5y) as a polynomial
olya-2409 [2.1K]

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.

The expression is given below

\rm \dfrac{2x}{7} \times (1.4x^2-3.5y)

The expression can be written in the form of the polynomial

\rightarrow \rm \dfrac{2x}{7} \times (1.4x^2-3.5y)\\\\\\\rightarrow \rm \dfrac{2x \times 1.4x^2}{7} - \dfrac{3.5y\times 2x}{7 }\\\\\\\rightarrow \dfrac{2.8x^3}{7} - \dfrac{7xy}{7 }\\\\\\\rightarrow 0.4x^3 - xy

The expression in the form of a polynomial is given as

\rm \rightarrow 0.4x^3 - xy

More about the polynomial link is given below.
