Answer:

Step-by-step explanation:

There are 2 ways of looking at this problem

Method A

100% of the price is 598.00

75% of the price is x

So set up a proportion

100/75 = 598/x                Cross Multiply

100x = 75 * 598               Simplify the right

100x = 44850                   Divide both sides by 100

100x/100 = 44850/100    

x = 448.50

Method Two

The other way is just to take 25% from 598

598 * 25/100 = 149.5

That's the amount of the reduction

598 - 149.5

448.5

Both answers work. You have to choose.

HELP ASAP IM STRUGGLING : The instructions on a box of chicken patties state that one patty should be cooked for 2.5 minutes in
AveGali [126]

Answer:

y= 1.5x + 2.5

Step-by-step explanation:

So slope intercept form is y= mx + b.

y is the number of minutes, so that will be on the left of the equal sign, not part of the math side of the actual equation, because it's the answer.

1.5x is the mx part because it's 1.5 minutes for each extra patty. So that would explain the x attached to it. so for each extra patty you add, that's what x would be.

The + 2.5 at the end, is just the time for the initial patty.

Hope this helps and is easy to understand! :)

Can somebody help me with that? Thank:)

The sum of the angles in a triangle is 180, so the equation will be :
2k+k+45= 180
add similar variables
3k+45=180
3k=135 (divide each side by 3)
k= 45
So 2k equals= 90
k=25
This is right angle triangle for your info!

Write the equation of the line that passes through (0, 3) and is parallel to the line 3x + 5y = 6.
Sunny_sXe [5.5K]
There's more ways than one to solve this, just as there's more ways than one to skin a cat.

Two paralle lines have the same slope, so the desired new line looks exactly like the given line 3x + 5y = 6, except that the constant, 6, is replaced by another value.

Write out 3x + 5y = c
Replace x with 0 and y with 3.  Then 3(0) + 5(3) = c, and c = 15.

Thus, the equation of the new, parallel, line is 3x + 5y = 15.
