Answer:
18 eagles
Step-by-step explanation:
Assuming Julie went bird-watching on each of those 6 days, she saw a total of ...
(3 eagles/day)(6 day) = 3·6 eagles = 18 eagles
Answer:
B. subtract 12 from both sides
Step-by-step explanation:
12-4x=54
<u>-12 -12</u>
<u>-</u><u>4</u><u>x</u><u>=</u><u>4</u><u>2</u>
To answer this item, we have 4 as the speed of the kayaker in still water and the speed of current be y.
When the karayaker moves upstream or against the current, his speed would be 4 - y. Further, if he moves downstream or with the current, the total speed would be 4 + y. The time utilized for the travel is equal to the ratio of the distance and the speed.
Total time = 9/(4 - y) + 9/(4 + y) = 6
We multiply the equation by (4-y)(4+y)
9(4-y) + 9(4 + y) = 6(4-y)(4+y)
Simplifying,
72 = 96 - 6y²
Transposing all the constants to only one side of the equation and rearranging,
6y² = 96 - 72
y² = 4
y = 2
Hence, the speed of the river's current is 2 miles/hr. <em>The answer is letter B.) 2 miles/hour.</em>
How many 3
wires can be cut from a spool of wire that is 100 inches long?
How many inches will be left over?
Number of pieces of wires = length of spool of wire ÷ length of each piece of wire.
Number of pieces = 100 ÷ 3 = 100 ÷ 
That gives 
Simplifying gives 
= 
This is equivalent to 26
pieces
So 26 pieces of wires can be cut from a spool and of a piece will be left over.
