Answer:
10
Step-by-step explanation:
if all of the sides across from it its 10
3y = 5x+30 , y+5x = 50
using elimination method ...
3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20
so using one of the original equations..
20 + 5x = 50
5x = 30
x =6
x = 6
y = 20
Lets do this week by week
beginning pressure 45 pounds
end of week 1
45 *.06 = 2.7
45 - 2.7 = 42.3
end of week 2
42.3 * .06 = 2.538
42.3 - 2.538 = 39.762
end of week 3
39.762 *.06 = 2.38
39.762 - 2.38 = 37.37
end of week 4
37.37* .06 = 2.2425
37.37628 - 2.2425= 35.12
end of week 5
35.12 * .06 = 2.107
35.12 - 2.107 = 33.012
end of week 6
33.012* .06 = 1.98
33.012 - 1.98 =31.03
Here is the fast way to get to this answer.
do 1-.06 = .94
then do
45(.94)(.94)(.94)(.94)(.94)(.94) = 31.04
-6x + 6y =6
-6x + 3y = -12
You would multiply the bottom equation by -1 to make -6x a positive so you can eliminate it.
-6x + 6y = 6
6x + -3y = 12
Eliminate -6y and add 6y to -3y as well as 6 and 12.
0 + 3y = 18
3y = 18
divide both sides by 3
y = 6
now that you know the value of y it will be easy to find x :)
