W+b=30

5.50w+8.75b=204

Use simultaneous equations to solve. Replace w with 30-b and plug into the second equation.

5.50(30-b)+8.75b=204
165-5.5b+8.75b=204
3.25b=39
b=12

She sold 12 belts.

What is the difference of the two polynomials? (7y2 6xy) â€"" (â€""2xy 3) 7y2 4xy â€"" 3 7y2 8xy â€"" 3 7y2 4xy 3 7y2 8xy 3.
svet-max [94.6K]

The difference between the polynomials is 7y² + 8xy - 3

Polynomials are functions that have a degree of <u>power greater than two.</u>

<u />

According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)

f(x, y) = (7y^2 + 6xy) - (-2xy + 3)

f(x, y) = 7y² + 6xy + 2xy - 3

f(x, y) = 7y² + 8xy - 3

Hence the difference between the polynomials is 7y² + 8xy - 3

Hhellp pwease I want to know what's wrong and right
Studentka2010 [4]

Answer:

A: False

B: False

C: True

D: True

E: False

F: True

G: True

H: True

Step-by-step explanation:

A: 9(x - 2) = 9x + 2

9x - 18 = 9x + 2 FALSE

B: 65 - y = y - 65

(equation rearranged) -y + 65 = y - 65 FALSE

C: g (times) h = h (times) g     (TRUE due to the commutative property of multiplication)

D: a (times) 0 = 0      (TRUE because anything times 0 equals 0)

E: (4 (times) 2) - r = 4 (2 (times) r)

8 - r =  8 - 4r FALSE

F: k + 0 = k TRUE

G: (a + x) + y = a + (x + y)

a + x + y = a + x + y TRUE

H: 5(2x - 9) = 10x - 45

10x - 45 = 10x - 45 TRUE

<em>Answer:</em>

<h2><em>4</em></h2>

<em>Solution</em><em>,</em>

<em>2</em><em>(</em><em>4</em><em>x</em><em>+</em><em>3</em><em>)</em><em>=</em><em>1</em><em>0</em><em>x</em><em>-</em><em>2</em>

<em>or,</em><em>8</em><em>x</em><em>+</em><em>6</em><em>=</em><em>1</em><em>0</em><em>x</em><em>-</em><em>2</em>

<em>or,</em><em>8</em><em>x</em><em>-</em><em>1</em><em>0</em><em>x</em><em>=</em><em>-</em><em>2</em><em>-</em><em>6</em>

<em>or,</em><em>-2x=</em><em>-</em><em>8</em>

<em>or,</em><em>X=</em><em>-</em><em>8</em><em>/</em><em>-</em><em>2</em>

<em>X=</em><em>4</em>

<em>Hope </em><em>it</em><em> helps</em>
