Answer: m=6, m=-4
Step-by-step explanation:
To solve this proportion, we have to cross multiply.
Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.
Combine like terms.
We can move all terms to one side and then solve for m.
We can actually factor this to:
We set each factor equal to 0 to find m.
m-6=0
m=6
m+4=0
m=-4
Answer:
670 animals
Step-by-step explanation:
First, round both numbers to the nearest ten. Remember that the numbers 4 and under round down (e.g. 143 = 140) and the numbers 5 and above round up (e.g. 145 = 150).
218 = rounds up = 220
454 = rounds down = 450
Finally, add the rounded numbers together.
220 + 450 = 670
The zoo has approximately 670 animals.
