Answer:

(8 * x) + 2x = 60

8x + 2x = 60

10x = 60

/10 /10

x = 6

8 is a constant that is being multiplied by an unknown number which we will name x. It is then being added to two times the unknown number(x), so we multiply x by 2, which is 2x. The final product will be 60, so in the equation it'll then equal 60.

We consider "a number" to be a variable that withholds an unknown value, which is x (or any other variable you prefer).

Answer:

$B = \frac{3}{2} * 21,356$

Step-by-step explanation:

Given

Represent Jimmy with J and Bob with B

$J = 21,356$

$B = 1\frac{1}{2} * J$

Required

Determine the expression for B

$B = 1\frac{1}{2} * J$

Substitute 21,356 for J

$B = 1\frac{1}{2} * 21,356$

Convert Mixed fraction to improper

$B = \frac{3}{2} * 21,356$

The above is an expression for B

Solving further, we have

$B = \frac{3 * 21,356}{2}$

$B = \frac{64068}{2}$

$B = 32034$

3. Antony and Cleopatra are 100 miles apart . To meet at a planned location , Antony travels at 12 mph and Cleopatra travels at

Vlad1618 [11]

Answer:

60 miles

Step-by-step explanation:

Distance apart = 100

Rate of travel. :

Anthony = 12 mph

Cleopafda = 8 mph

Using the relation :

Speed = distance / time

Distance = speed * time

If they leave at the same time, travel time Can be represented as x

Anthony's distance + Cleopafda distance = total distance

12x +. 8x = 100

20x = 100

x = 5

Hence, they both traveled for 5 hours before meeting.

Distance covered by Anthony :

Speed * time

12 mph * 5h = 60 miles

Anthony must travel. For 60 miles.
