Answer:
The first thing you do is make the denominators equal on both sides.
Step-by-step explanation:
As a example if you have the equation:
+ =
you would multiply the denominator by the smallest multiple. I would do 2 * 5= 10
this would make the equation
next you have to do the same with the numerator.
so sence you multiplied the by five you will get
same with the other fraction except you multiplied it by two. x 2 =
next you add and simplify if needed
Answer:
Step-by-step explanation:
$3/(2 batteries) = $1.50/battery
$15/(12 batteries) = $1.25/battery
Not proportional.
Hey there!
You can use subtraction:
1,897 - 834 = 1,063
1,063 + 834 = 1,897
x = 1,063 <------- Answer
Hope this helps
Have a great day (:
Answer:
-10.21 radians
Step-by-step explanation:
2π radians =360°
1radian=360°/2π
=57.2958°
Therefore to get the number of radians in -585°,
letting the number of radians to be x, we can calculate
if 1radian=57.2958°
x radians=-585°
the following expression is thus obtained
x=(-585°×1)/57.2957°
=-10.21radians
Answer:
<em> y = 4.25x</em>
Step-by-step explanation:
Given that:
After 2 week he has used 8 1/2 cups of dog food after 5 week he has used 21 1/4 cups, we can write this in coordinate form (x, y) where;
y is the amount of dog food
x is the time in weeks
The coordinates are (2, 8 1/2) and (5, 21 1/4)
get the slope m:
m = y2-y1/x2-x1
m = (21 1/4 - 8 1/2)/5-2
m = (85/4-17/2)/3
m = (85-34/4)/3
m = 51/12
m = 4.25
Get the intercept c:
Substitute any of the points say (2, 17/2) and m = 51/12 into the equation
y = mx+c
17/2 = 51/12(2) + c
17/2 = 51/6 + c
c = 17/2 - 51/6
c = 51-51/6
c = 0
Get the required equation:
substitute m - 4.25 and c = 0 into y = mx+c
y = 4.25x + 0
<em>Hence the required equation is y = 4.25x</em>
