The amount of money Mr. Brust made this summer was equal to the $55 he started with and the $15 for every lawn he mowed while st

earnstyle [38]

Let's start by declaring our varibles.

x = number of lawns Mr. Brust mowed

y = total amount of money Mr. Brust made

Let's create our equation.

y = 15x + 55

For part b, we can plug 800 in for y.

800 = 15x + 55

Subtract 55 from both sides.

745 = 15x

Divide both sides by 15

50 = x. Note, I rounded the answer to the nearest integer.

For part c, we can plug 13 in for x.

y = 15(13) + 55

Simplify the right side of the equation.

y = 250

Step-by-step explanation:

$(a+b)^{2} =a^{2} +2ab+b^{2}$

e.g.

$(x+9)^{2} =x^2+2(x)(9)+81$

$(x+9)^{2} =x^2+18x+81$

Verify this closure property of subtraction x= -4/5 , y= 1/-10

Rom4ik [11]

Answer:

x - y is also a rational number. Hence satisfies the closure property.

Step-by-step explanation:

$x =\frac{-4}{5} , y = \frac{1}{-10} = \frac{-1}{10}\\$

Closure property of subtraction states that for any two integers a and b, (a - b) must also be an integer.

Here x and y are rational numbers. so x - y must also be rational to satisfy the closure property.

$x - y = -\frac{4}{5}- ( - \frac{1}{10}) = -\frac{4}{5} + \frac{1}{10} = \frac{-8 +1 }{10} = \frac{-7}{10}$
