Answer:
q = 20
Step-by-step explanation:
1/5q = 4
q = 20
X<0
y > 0
so x is negative and y is positive
Quad. II
answer
Quadrant II
X= [ 2*(-3)+ 3*(2)/( 2+3) = 0
y = [ 1*3+ 6*2 ]/2+3 = 3
so P is( 0,3 )
if it lies on the line x+ 5y = 15 then this point should satisfy the equation
so 0 + 5*3 = 15
so Plies on the given line x - 5y + 15 = 0
The perimeter is the sum of all sides. Start by listing out what the sides are given to be. Assign a variable to anything unknown.
1st side = x
2nd side = y
3rd side = z
Given: 1st side is 5 less than 2nd side.
x = y - 5
Given: 3rd side is 2 less that 1st side. But we want everything in only one variable to solve. So use the first given 1st side = y - 5
z = y - 5 - 2
z = y - 7
Sum of sides
(y - 5) + y + ( y - 7) = 42
3y - 12 = 42
3y = 42 + 12
3y = 54
y = 54/3
y = 18
Remember the sides, We have
1st, x = y - 5
= 18 - 5
= 13
2nd, y = y
= 18
3rd, z = y - 7
= 18 - 7
= 11
Answer:
56.7%
Step-by-step explanation:
30-13=17
(on a scientific calculator) 17/30=
0.56666667 x 100= 56.7 (round it up)
you can use this method everytime when trying to find a percantge.
