Method 1 of solving: 13.50 · 1.10 = 14.85

Method 2: (13.50 ÷ 10) · 11

Method 3: 10% of 13.50 is 1.35, so 13.50 + 1.35 = 14.85

What equation can be used?
Kryger [21]

Answer:

f(x)=89x+1800

Step-by-step explanation:

$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total

$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

f(x)=89x+1800

Area of aqua: A = bh/2 = (13.4cm) (4cm)/2 = 26.8cm2

Total area trapezoid: A = (a+b/2)h = ((13.4cm + 18cm)/2) 4cm = 62.8cm2

Area of purple = Total area - area of

What is the value of x and y?
Pavel [41]

Answer:

x=\boxed{2}

y=\boxed{4}

Step-by-step explanation:

\begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases}

From equations (1) & (2), we find:

6x - 8 = - 3x +10

\therefore 6x+3x = 8+10

\therefore 9x = 18

\therefore x =\frac{18}{9}

\therefore x = 2

Plug x = 2 in equation (1)

y = 6(2)-8 = 12-8 =4

So,

x=\boxed{2}

y=\boxed{4}
