Isolate x. First, add 2/5 to both sides
x - 2/5 (+2/5) = 1/3 (+2/5)
x = 1/3 + 2/5
to simplify, find common denominators (15 in this case). Multiply the same number to both the denominator and numerator
(1/3)(5/5) = 5/15
(2/5)(3/3) = 6/15
x = 5/15 + 6/15
Simplify
x = 11/15
11/15 is your answer for x
hope this helps
Answer:
y=-4/5x-1 3/5
or you can write as
y=-4/5x-8/5
Step-by-step explanation:
m=y1-y2/x1-x2
m=0-(-4)/-2-3 input
m=4/-5 solve
m=-4/5
we will find y-intercept now
we will input the points and the slope into the equation to find b
y=-4/5x+b
0=-4/5(-2)+b input
0=8/5+b multiply
-8/5=b isolate b
-1 3/5=b make improper fraction mixed number
so the y-intercept is -1 3/5
if we plug everything in we have equation
y=-4/5x - 1 3/5
or write y-intercept as improper fraction like
y=-4/5x - 8/5
Answer:
x=18
Step-by-step explanation:
The answer is 36 because you have to add the perimeter of each side
1/17r - 17 = 42
1/17r = 42 + 17
1/17r = 59
r = 59 * 17/1
r = 1003 <== Rhode Islands population density (r)
