Answer:

Step-by-step explanation:

do 20.50 minus 13.50 but you can just take out the .50 because both sides have them and they will cancel out anyways then its just 20 minus 13 and that is 7.

Write an equation of a line that is perpendicular to

Ulleksa [173]

Answer:

y = (-3/2)x + 4

Step-by-step explanation:

The slope of the given line is 2/3. The slope of any line perpendicular to the given line is the negative reciprocal of 2/3, which comes out to -3/2.

Now we have the slope of the new line and know that it passes through (0, 4). (0, 4) happens to be the y-intercept, b, in y = mx + b:

Substituting -3/2 for m and 4 for b, we get y = (-3/2)x + 4.

Jim's backyard is a rectangle that is 12 5 6 yards long and 10 2 5 yards wide. Jim buys sod in pieces that are 1 1 3 yards long

Alborosie

Answer: 75

Step-by-step explanation:

In order to cover his backyard with sod, he needs to cover the area of the backyard.

His backyard is a rectangle, and area of a rectangle represented by A is given as l*w

Where,

is the length, and

is the width

So, the area of Jim's backyard is square yards.

l*w=12/5/6*10/2/5=2002/15 or 133.466

The area of each sods are solved using the area of the rectangle formula.

l*w=1/1/3*1/1/3=16/9

To find HOW MANY of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:

=2002/15 divided by 16 /9=3003/40or 75.075

Since, fractional sods can't be bought, Jim has to buy 75 sods approximately .

Use addition to solve the linear system of equations. <br> x-y=4 <br> x+2y=4

ICE Princess25 [194]

Hey, There 20percntcooler! :)

To solve these equations, we will need to substitute.
$x-y=4$
or
$4+y=x$

We can substitute this for x so, we don't have to deal with two different variables.
$x+2y=4$
or if substituted:
$4+y+2y=4$

Solve for y.
$4+y+2y=4$
Add like terms.
$4+3y=4$
Subtract 4 from both sides.
$(4+3y)-4=(4)-4$
$3y=0$
Divide both sides by 3.
$(3y)/3=(0)/3$
$y=0$

Now lets input the value for y into the equation to find the value of x.
$x-0=4$
Add 0 to both sides.
$(x-0)+0=(4)+0$
$x=4$

$x=4$
$y=0$

Hope this helps.
