Answer: 4 is 12.5% of 32
Step-by-step explanation:
12.5/100 = 0.125
4/0.125 = 32
Step-by-step explanation:
since all angles add up to 180:
(8x-1)+(3x+4)+(3x+9)=180
add like terms:
14x+12=180
x=12
Hope that helps :)
Answer:
x= 22
y = 35
Step-by-step explanation:
The base angles of a isosceles triangle are equal
3x-11 = 2x+11
Subtract 2x from each side
3x-2x -11 = 2x-2x+11
x-11 = 11
Add 11 to each side
x-11+11 = 11+11
x = 22
The sum of all the angles in a triangle is 180
3x -11 + 2x+11 + 2y = 180
Combine like terms
5x +2y = 180
5*22 + 2y = 180
110 + 2y = 180
Subtract 110 from each side
110+2y-110 = 180-110
2y = 70
Divide by 2
2y/2 =70/2
y = 35
Step-by-step explanation:
conditional :
3-2x ≥ 0
-2x ≥-3
x ≤ 3/2
1-x ≥ 0
-x≥ -1
x ≤ 1
so, the domain is:
{ x | x € the Real numbers, x ≤ 1}
