Answer:
volume of old tank=20×4×10=800m³
no of shark adjust =800/25=32 sharks is adjusted in old shark tank
for new
if length=25℅0f 20+20=25m
breadth=25%of 4 +4=1+4=5m
height is same=10m
new volume =25×5×10=1250m³
total no.of shark adjust=1250/25=50 shark
50-32=18 more shark that the new tank hold.
Answer: There are 5 grasshoppers, 15 crickets and 20 ladybugs
Step-by-step explanation:
The question in english is:
Jose has found several insects. There are 10 less grasshoppers than crickets. There are 5 less crickets than ladybugs. If Jose has found 5 grasshoppers, how many ladybugs did he find and how many crickets? Write two equations to solve the problem.
Let's tag grasshoppers with
, crickets with
and ladybugs with
.
So, we are tolde there are 10 less grasshoppers than crickets:
(1) We have the first equation
Then, we are told there are 5 less crickets than ladybugs:
(2) This is the second equation
If
and we substitute this in both equations we will have:
(3)
Isolating
:
(4) There are 15 crickets
Substituting (4) in (2):
(5)
Isolating
:
There are 20 ladybugs
Therefore:
There are 15 crickets and 20 ladybugs
