D=deana's age
b=bernice's age
sum is 48
b+d=48
8 years from now, dena will be 3 times bernice age
d+8=3(b+8)
ok we gots
d+b=48
d+8=3(b+8)
d+b=48
minus b from both sides
d=48-b
subsitute 48-b into the other equation for d
d+8=3(b+8)
48-b+8=3(b+8)
56-b=3b+24
add b to both sides
56=4b+24
minus 24 both sides
32=4b
divide both sides by 4
8=b
bernice is 8 years old
The experimental probability is what you actually rolled
24/60 = 2/5 = 40%
The theoretical probability is what we expect to happen
=number of even numbers / total number of numbers
3/6 = 1/2 = 50%
Answer:
C $250
Step-by-step explanation:
based on the question we can get the equation
where m = money, the years are converted to months
15000 = 60m
divide by 60 to each side
m= 250
3r - 8 = 7 + 8r (make rs on 1 side, numbers on other)
5r = -15(divide by 5 now)
r = -3 (<---Answer)
Hope this helped!
I’m pretty sure that the answer is D
