Answer:

200km

Step-by-step explanation:

Car A purchase worth = $14000

Car B purchase worth = $15000

Car A drive worth= 25€ per km

Car B drive worth= 20€ per km

For the worth of the two cars to be equal let's first assume all of the currency to be in dollars$

For A

Worth= 14000+25(x)

For B

Worth= 15000+20(x)

Where x is the distance covered

For the both worth to be equal we equate.

14000+25(x)= 15000+20(x)

25x-20x= 15000-14000

5x= 1000

X= 200

The distance covered by the two cars for the worth to be equal is 200km

What is the solution to the linear equation?

KIM [24]

4b + 6 = 2 - b + 4

Combine like terms on the right side:

4b + 6 = -b + 6

Subtract 6 from both sides:

4b = -b

Add 1b to both sides:

5b = 0

Divide both sides by 5:

B = 0

A (1, 1)

Savatey [412]

Answer:

D(4, 1)

Step-by-step explanation:

The two diagonals have the same midpoint, so ...

(A+C)/2 = (B+D)/2

A+C = B+D . . . . multiply by 2

A+C-B = D . . . . . subtract B

D = (1, 1) + (5, 3) - (2, 3) = (1+5-2, 1+3-3)

D = (4, 1)

Misha and her cousin Darius made muffins for the Clark family reunion. Misha made 17 more muffins than Darius. Dark is made 56 m

VMariaS [17]

Answer:

Number of muffins per plate.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of muffins made by Dark

Then, number of muffins made by Misha =

$x + 17$

For x = 56

Muffins made by Dark = x = 56

Muffins made by Misha =

$x + 17 = 56 + 17 = 73$

Total number of muffins =

$56 + 73 = 129$

Total number of plates = 12

Number of muffins on each plate =

$=\dfrac{\text{Total number of muffins}}{\text{Total number of plates}}=\dfrac{129}{12} = 10.75\approx 11$

Thus, there were approximately 11 muffins on each plate.

Thus, the unit of this problem is number of muffins per plate.
