Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "<em>more</em>"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.
Answer:
Step-by-step explanation:
x= base
one side= x-6
other side= 4+x
x+x-6+4+x = 43
3x=43+2
x=15 length of base
The scientist was 83.5 feet below sea level while studying ocean life.
Given that:-
Distance the scientist ascended after studying the ocean life = 61.9 feet
Distance below sea level the scientist is after ascending = 21.6 feet
We have to find the distance by which the scientist was below sea level while studying the ocean life.
We know that,
Distance by which the scientist was below sea level while studying the ocean life = Distance the scientist ascended after studying the ocean life + Distance below sea level the scientist is after ascending
Hence, we can write,
Distance by which the scientist was below sea level while studying the ocean life = 61.9 + 21.6 = 83.5 feet.

"Rate of change" is another name for "slope".
In the table, every time 'x' increases by 2, 'y' also increases by 2.
So the rate of change (slope) of the function in the table is
(change in 'y') / (change in 'x') = 2/2 = 1 .
The rate of change (slope) in the function y = x + 4 is
the coefficient (number before) the 'x'. That's also ' 1 '.
So t<span>he rate of change in the function y = x + 4 is the same as (equal to)
the rate of change of the function represented in the table.</span>
