Answer:
x=5
Step-by-step explanation:

add 11 to both sides

Divide 4 on both sides

Take the square root of both sides to eliminate the power of two from x

Simplify

Answer:
(a) 
(b) 4 miles
Step-by-step explanation:
Given:
The sequence of run is an arithmetic sequence.
Miles traveled on day 1 = 1 mile
Miles traveled on day 7 = 2 miles
(a).
Explicit formula for an arithmetic sequence is given as:

Here, 
So,

Therefore, the explicit definition of the above sequence is given as:

Where,
is the miles covered on
day.
(b)
In order to find the distance covered by her on day 19, we plug in 19 for n in the above formula. This gives,

Therefore, the number of miles covered by her on day 19 is 4 miles.
For this case we have the following equation:
Density = mass / volume
If the volume is the same, then the object with the greatest weight will be the one with the highest density.
You must know the type of way to know the value of the density.
Answer:
The weight of the blocks will depend on the density if the volume is the same.
1 1/4?? because 7/4 cant be a whole number its a mixed number when simplified
Answer:
25.4575
Step-by-step explanation:First since one candy is 5.99 we multiply it by 4 1/4 ponds and then we get $25.4575
