Answer:
15
Step-by-step explanation:
1 dime = 10
1 quarter=25
x=number of coins - dimes
y= number of coins - quarters
x (10)+y(25)=10.25
x+y=50
x= 50-y
x(10)+y(25)=1025
(50-y)(10)+25y =1025
500-10y+25y=1025
500+15y=1025
15y= 1025 - 500
15y=525
y=525/15
y=35
x= 50-35=15
It by root you mean radical equations, well then I can’t help you there, as there is too much stuff to cover.
If you mean zeros, then to find the root of a function you just find the zeros.
C, or the last photo, shows a reflection.
Answer:
D
Step-by-step explanation:
Given that the segment is an angle bisector then the ratio of sides and base are equal, that is
= ( cross- multiply )
10x = 72 ( divide both sides by 10 )
x = 7.2 → D
