Answer:

There is no x to solve, so I will solve for y.

y=-1.8

What I did was simplify and get the term one side.

Answer:

y = -1.8

Step-by-step explanation:

0.6+(0.5y-1)=y+0.5

the parenthesis can be remove because there is no multiplication

0.6 + 0.5y - 1 = y + 0.5

now combine numbers

0.6 - 1 + 0.5y = y + 0.5

-0.4 + 0.5y = y + 0.5

subtract 0.5 from both sides

-0.4 - 0.5 + 0.5y = y

-0.9 + 0.5y = y

now subtract 0.5y from both sides

-0.9 = 1y - 0.5y

-0.9 = 0.5y

now divide both sides by 0.5 and switch

y = -1.8

Maslowich

Answer:

x = \frac{2A}{y}

Step-by-step explanation:

Given

A = \frac{1}{2} xy

Multiply both sides by 2 to clear the fraction

2A = xy ( divide both sides by y )

\frac{2A}{y} = x

dmitriy555 [2]

Tony’s club is selling oranges to raise money. For every box they sell, they get 1 1/8 dollars profit. They have sold 75 boxes already. How many more boxes must they sell to raise 180 dollars?

Answer: We are given:

The amount of money Tony's club get for every box they sell =1 \frac{1}{8} =1.125 dollar

They amount of money Tony's club has raised by selling 75 boxes is:

75 \times 1.125=84.375 dollars

The amount of money Tony's club is required to raise = 180 dollars

The remaining need to be raised is :

180-84.375=95.625 dollars

Therefore, the number of more boxes to be sold are:

\frac{95.625}{1.125}=85

Hence, 85 more boxes they must sell to raise 180 dollars

What is the answer to the equation x squared minus 2x equals 15.
anzhelika [568]

Answer:

x = 5 \\ x =  - 3

Step-by-step explanation:

{x}^{2}  - 2x = 15 \\  {x}^{2}  - 2x - 15 = 0 \\  {x}^{2}   + 3x - 5x - 15 = 0 \\ x(x + 3) - 5(x + 3) = 0 \\ (x - 5)(x + 3) = 0 \\ x - 5 = 0 \:  \:  \:  \:  \: or \:  \:  \:  \: x + 3 = 0 \\ x = 5 \:  \:  \:  \: or \:  \:  \:  \:  \:  \: x =  - 3
