The space shuttle can travel at 28968 km/h what distance can it cover in 8 hrs?
Verdich [7]

Given:

A space shuttle can travel at 28968 km/h.

To find:

The distance it can cover in 8 hrs.

Solution:

We have,

Speed of space shuttle = 28968 km/h.

So,

Distance covered by the space shuttle in 1 hour = 28968 km/h.

Distance covered by the space shuttle in 8 hour = (28968 × 8) km

                                                                                 = 231744 km

Therefore, the distance it can cover in 8 hrs is 231744 km.

VMariaS [17]

Answer:

Her first coupon ti be used is $50 off a purchase above $300

Final purchase price= $340

Step-by-step explanation:

Marie has two coupons

one for a 15% discount and one for $50 off any purchase above $300.

The stores allow the two coupons to be combined and she spends a total of $450.

Her first coupon ti be used is $50 off a purchase above $300.

So Marie have $400 now

15% off $400= 400-(0.15*400)

15% off $400 = 400-60

15% off $400 =$ 340

What is the solution to this equation?<br> 9x - 4(x - 2) = x + 20
ioda

9x - 4(x - 2) =x + 20

We move all terms to the left:

  • 9x -4(x - 2) - (x + 20) = 0

Multiply

  • 9x - 4x -(x + 20) + 8 = 0

We get rid of the parentheses.

  • 9x - 4x - x - 20 + 8 = 0

We add all the numbers and all the variables.

  • 4x - 12 = 0

We move all terms containing x to the left hand side, all other terms to the right hand side

  • 4x=12
  • x = 12/4
  • x = 3
