So, for the second problem, they've reversed the situation: Now we have the temperature, and we have to think backwards to figure out the number of cricket chirps (in five minutes)!
We ended up with 60 degrees (somehow). Well, let's subtract 37. That gives us 23. What does this number mean? It is the number of times the cricket chirps in 15 seconds. But we want five minutes... I bet you can take it from here... :)
Answer:
It could be 9 or 23. It could also be many other things.
Step-by-step explanation:
The other side of the triangle has to be greater than 15 when added to 7 or greater than both when they are added together.
If the proportion of iris to roses in Nikki's garden is 2: 5, it means that for 25 roses: (2/5) = (10/25). Therefore to maintain the proportion by adding 20 roses: (2/5) = (18/45). The number of irises after the addition of roses will be 10 + 18 = 28 irises.
Let the variable be x
A number isn’t given so pick any number.
Let’s use 10
Set up the equation to get:
X + 10 = -8
Solve for the variable by subtracting 10 from both sides:
X = -18
Let the variable be y and pick any number, let’s use the number 2.
Equation: 2 x y = 4/5
Solve for y by dividing both sides by 2:
Y = 2/5
