Answer:

11

Step-by-step explanation:

first divide 715 and 13, which is 55

then you divide 605 and 55, which is 11

so he drove 605 miles in 11 hours.

Answer:

The time it would take Deandre to drive 605 miles is 11 hours.

Step-by-step explanation:

The problem is related to speed, distance and time.

Speed (or rate) of an object is the measure of how rapidly the object moves form point A to point B.

It is computed by dividing the distance traveled by the time taken to travel this distance. That is,

Speed=\frac{distance}{time}

It is provided that Deandre drove distance=715 miles in time=13 hours.

Then the speed at which Deandre was driving can be computed as follows:

Spped=\frac{distance}{time}\\ =\frac{715}{13}\\ =55

Thus, Deandre's speed was 55 miles/hour.

Now, if Deandre needs to drive 605 miles at the same speed, i.e 55 miles/hour, then the time taken will be,

Speed=\frac{distance}{time}\\time=\frac{distance}{speed}\\=\frac{605}{55}\\ =11

Thus, the time taken by Deandre to drive 605 miles at the speed 55 miles/hour is, 11 hours.

Solve for the variable a D =a+b-c/3
yuradex [85]
Hey there,
solving for a is just like you think of all other letter as a constant
i.e the only variable is a
so you need to subtract b as a start
      d=a+b-c/3
-b             -b
=============

    -b+d=a-c/3                now it's time to add c/3 (isolate a by itself in one side)

     -b+d=a-c/3
+c/3         +c/3
==============
c/3-b+d=a

Hence you have solved for a

FCD=x+41, BCF=x+78, BCD=95. Find x
Lorico [155]
You'll set the two expressions equal to 95.
So 2x+119=95
Then 2x=-24
Finally x=-12

Write an explicit formula for a_n, the nth term of the sequence 4, -20, 100, ...
saw5 [17]

Answer:

a_{n} = 4 (-5)^{n-1}

Step-by-step explanation:

There is a common ratio r between consecutive terms , that is

r = - 20 ÷ 4 = 100 ÷ - 20 = - 5

This indicates the sequence is geometric with nth term ( explicit formula )

a_{n} = a₁ (r)^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 4 and r = - 5 , then

a_{n} = 4 (-5)^{n-1}

Eleven plus forty-one is divided by a number. If the result is 13, what's the number?
sergij07 [2.7K]

Answer:

4

Step-by-step explanation:

Let the number be x.

(11+41)/x = 13

52/x = 13

13x = 52

x = 52/13

x = 4
