Step-by-step explanation:
3x+2y=2------------1
-3x+5y=5-----------2
adding 1 and 2 we get
7y=7
y=1
and from (1),we get
3x+2×1=2
3x=0
x=0 is the required value of x.
X and y are proportional hence when y is multiplied by a number, x is multiplied by the same number.
18=6*3 hence when y=18,x=9*3=27
x=27
Answer:
68
Step-by-step explanation:
Add all of the numbers together then divide by the amount of numbers there are.
10 is the answer because using the Pythagorean theorem 6^2 + 8^2 = 100. The square root of 100 would be 10
