1. X/Y = Z
if x = 6, y = 2, then z = 3, not even
if x = 6, y = 3, then z = 2, even
<span>2. Z=XY </span>
so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)
<span>Sufficient, as if square of an integer is even ,then the integer is even</span>
20x+50=450
-50 -50
20x=400
Divide both sides by 20
X=20
Answer:
1/8 as a fraction
Step-by-step explanation:
Answer:
Length of x+3= 6.75
Length of 4x=15
Length of 3x-1=10,25
Step-by-step explanation:
- First make an equation and find x x+3+3x+1+4x=34
- Then solve for x, answer will be 3,75
- 3,75 represents x
