They will spend 4 1/4 hours at the aquarium. The students will need to visit five exhibits while they are there. If the time is evenly distributed, how many minutes will the students spend at each exhibit? Ask for details; Follow .... Given that 3x + y = 0 and 2x - y = 5, find the value of y. Estimate.0.143 divided
Step-by-step explanation:
Elvira (e) is 5 years older than Morton (m)
e = m + 5
Morton (m) is twice as old as Michelle (c)
m = 2c
The combined total of their ages is 85
e + m + c = 85
We want m at the end so let's write everything in terms of m.
e = m + 5
c = m/2
85 = e + m + c = m+5 + m + m/2 = 5 + (5/2) m
m = (2/5) (85 - 5) = 32
Answer: 32 years old
Check:
That makes Elvira 37 and Michele 16, total 32+37+16=85, good
Answer: 80
Step-by-step explanation: multiple b(3) with everything its next to, then add it all up
6x-8=16
