zaharov [31]

Answer:

x = 13.4

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

x² + 6.8² = 14.1²

x² = 14.1² - 6.8²

x² = 152.57

Take the square root of both sides

x = 12.3519229272

Rounded

x = 13.4

Belinda bought a car one year ago.
lesya692 [45]

Answer:

$16,500

Step-by-step explanation:

The computation of the amount that should be paid for the car is shown below:

Since the car would be purchased one year ago

And, the value of the car would be decreased by 15% to $14025

So the amount that should be paid is

= $14025 × 100 ÷ (100 - 0.15)

= $16,500

Answer:

1) 4+5=9.

2)  2+(-6)=-4

3)  -3+(-7)=-10

4)  (-7)+3=-4

5)  9+(-4)=5

6)  -1+4=3

In first number line we have two rightarrows.

Rightarrow from 0-4 = 4

Rightarrow from 4-9 = 5

2+(-6)=-4

3)

-3+(-7)=-10

4)

(-7)+3=-4

5)

9+(-4)=5
