A triangle is 1/2 bh so .5*8*6 which equals 25 cm square. hope I helped. brainliest would be much appreciated because I am trying to rank up!!!
The sum of x and y decreased by their product...
(x + y) - xy <== ur expression
Answer:
A. x = -3/10 , y = 69/20
B. x = 1/2 , y = 5/2
Step-by-step explanation:
A]
3x + 2y = 6......eq1
13x + 2y = 3.......eq2
From eq 2 - eq 1
10x = -3
x = -3/10
So,
3x + 2y = 6
3(-3/10) + 2y = 6
y = 69/20
B]
6x+2y = 8.....eq1
3x - y = -2.....eq2
eq2 x 2 and add in 1
12x = 6
x = 1/2
So,
6x+2y = 8
y = 5/2
Answer:
radius = C / 2π :)
Step-by-step explanation:
The circumference is 2πr, right?
Let's put this information into an equation :)
C = 2πr
Now, we can simply divide both sides by 2π here to isolate r (the radius) by itself, because that's what we want! (Something equal to the radius)
C / 2π = r
There's your answer! :)
