1.44 per kg
take 1.3 x 2, then subtract 12.7, finally divide that by 7
You need to add a -1
We can find this by setting up the equation like so
x + (-6) + 12 + 15 / 4 = 5
x + 21 = 20
x = 20 -21
x = -1
Now if we insert -1 where x is located in the equation, you will get a means of 5
First, create an equation with the criteria given.
If we let x be your number,

(

is twice the product of 3 and x, and if it exceeds

by 10, then we add 10 to

to make the two sides of the equation equal.)
Now, solve for

.
Answer:
12.5%
Step-by-step explanation:
8+4+4=16
2/16*100=12.5
12.5%
Solve x by simplifying both sides of the equation & then isolating the variable x=-4 & the negative comes in from the -12
