If 16 gallons of water evaporates per week and we have 24 weeks, we can jsut multiply it.
So $16*24=384$ gallons of water evaporates.

What is the solution to the equation?

AleksandrR [38]

Solution of the equation: $x=6\frac{1}{2}$

Step-by-step explanation:

The equation that we have to solve in this problem is:

$13\frac{3}{4}+x=7\frac{1}{4}$

The first step to do is to rewrite the mixed fractions as improper fractions. We have:

$13\frac{3}{4}=\frac{13\cdot 4+3}{4}=\frac{52+3}{4}=\frac{55}{4}$

And

$7\frac{1}{4}=\frac{7\cdot 4+1}{4}=\frac{29}{4}$

So the equation becomes

$\frac{29}{4}+x=\frac{55}{4}$

Now we multiply by 4 each term on both sides, and we get

$29+4x=55$

Now we subtract 29 from both sides,

$4x=55-29=26$

And finally, we divide both sides by 4:

$x=\frac{26}{4}=\frac{13}{2}=6\frac{1}{2}$

Options: <br> y= -2x - 6<br> y= 2/3x + 6<br> y= -2/3x + 6<br> y=2x + 6

melisa1 [442]

Answer:

y = - $\frac{2}{3}$ x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 2) ← 2 points on the line

m = $\frac{2-6}{6-0}$ = $\frac{-4}{6}$ = - $\frac{2}{3}$

The line crosses the y- axis at (0, 6) ⇒ c = 6

y = - $\frac{2}{3}$ x + 6 ← equation of line
