Answer:
x=1
Step-by-step explanation:
20(3x-3/5) = 20(2x-2/4)
12x-12= 10x-10
12x-10x =12-10
x= 1
Answer:
m=60º
n=30º
Step-by-step explanation:
a triangle is 180º total
an equilateral triangle has all 60º angles
since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º
substituting the values 60+n=90
so n=30
Then since a triangle is 180º you can make an equation that says 180=90+m+n
again substituting 180=90+m+30
60=m
an easy way to check is 180=90+30+60 180=180

Answer:
In Fraction = 10/100 simplified = 1/10
Decimal = 0.1
Percentage = 10%
Step-by-step explanation:
We add all marbles = 5+ 3+ 2 = 10
Event 1 = Red = 5/10
Event 2 = Green = 2/10
We follow this path and multiply = 2 x 5 / 10 x 10 = 10/100 = 1/10
