2x+y=6
y=3x+4
The resulting equation is
5x=2
where
x=2/5
Because its a square all its sides are 5cm
So area of square is 5x5=25cm^2
Triangle is 5x4= 20
20/2 is 10cm^2
25+10=35cm^2
1 liter= 1000 ml
3 liter= 3000 ml
-7 = 2x + 8
Solve for x. First subtract 8 to both sides.
-7 - (8) = 2x + 8 - (8)
-15 = 2x
Divide by 2.
-15/(2) = -2x/(2)
x = -15/2 = -7.5
Answer:
1/5 + z = 3/5
Step-by-step explanation:
1/5 + z = 3/5
z = 3/5 - 1/5
z = 2/5
