Answer:
10
Step-by-step explanation:
x = Edith's age = 20 years
y = Ronald's age
x = 20 = y/4
y = 20×4 = 80 years
in z years we have
(x + z) = (y + z)/3
(20 + z) = (80 + z)/3
3(20 + z) = 80 + z
60 + 3z = 80 + z
60 + 2z = 80
2z = 20
z = 10
in 10 years Edith's age will be 1/3 of Ronald's age.
then Edith will be 30, and Ronald will be 90.
30 = 90/3
correct.
Step-by-step explanation:
Tan30=4/adj
adj Tan 30= 4
adj=4/tan30
adj=6.93m
Area=L×b
4×6.93=27.72m
Mary, She drank 3/8 and half would be 4/8. So 3/8 is less than 4/8. Please mark brainiest.
First you’ll subtract the base fee, which is 19.95 from the price payed, 243.81
243.81
-19.95
223.86
Now take 223.86, your remainder and divide it by .91, you will get 246, meaning Jim traveled 246 miles.
Answer: Jim travelled 246 Miles.
