Answer:
a=7.75
Step-by-step explanation:
19 = 4a − 12. 19+12=31. 31/4=7.75
Answer:
Solution given:
slope(m)=½
passing through point (x',y')=(0,3)
now
equation of a line is:
y-y'=m(x-x')
y-3=½(x-0)
y=½x+3
<u>D</u><u>.</u><u>y</u><u>=</u><u>½</u><u>x</u><u>+</u><u>3</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>equation</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>line</u><u>.</u>
To do this you have to fill in the equation

, but you don't know the height, so we'll use

for height. Plugging in the numbers you gave me, the equation is:

. To solve this, we need to find

. To find height you do

. Doing this, we get

=
3.75 ft.Hope this helped!
(11/12) / 3 =
11/12 * 1/3 =
11/36 qts per glass <==
Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10
