Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation 
. From there we can solve for x.
Firstly, multiply both sides by 5: 
Next, divide both sides by 4 and your answer will be 
Answer:
12x
Step-by-step explanation:
8x+6x-3x
8x+3x
12x
hope it helped.
Hello :
let the equation : y = ax+b
<span>xx-intercept (4.5,0) : 0 = a(4.5) +b .... (1)
</span><span>yy-intercept (0,-5.4) .: - 5.4 = a(0)+ b .....(2)
by (2) : b = - 5.4
subsct in (1) : 4.5a -5.4 = 0
a = 5.4/4.5
a = 54/45
a = 6/5
</span><span>the equation of the line (in slope intercept form) is : y =(6/5)x - 5.4</span>
Perimeter is the distance around a shape. The way you find it is by adding the lengths of every side.
In this case, it is 3+4+5=12 cm
Answer:
I believe it should be (-4,2)
Explanation:
You can use substitution to solve this, so
1/4x+3 = 2x+10
(Because they both = y)
Then solve for x
X=-4
Then you plug x into one of the equations to solve for y. I used y=1/4(-4)+3
Hope this helps
