5. Basically you need to add the terms in the same positions in both matrices, so:

2 + 6 = 8 1 + (-4) = -3
-3 + 2 = -1 0 + 4 = 4

So the answer would be the first one :)

6. This one is not possible as to add or subtract matrices they must have the same order, which is not the case with this pair.

Fernando's family traveled 272 miles on a road trip last weekend. They drove for four hours. What was the rate at which Fernando
makvit [3.9K]
Total distance traveled by Fernando's family = 272 miles
Time taken to travel the distance of 272 miles = 4 hours
Then we can say that
The distance traveled by Fernando's family in 4 hours = 272 miles
So
The distance traveled by
Fernando's family in 1 hour = (272/4) * 1 miles
                                             = 68 miles
From the above deduction we can easily conclude that Fernando's family traveled at a rate of 68 miles per hour. I hope to have helped you.

Best buy is having a sale of 25% off all their computers. The original price on the computer was $1500 but there is a 8% shippin
skelet666 [1.2K]

Answer:

By 19% the computer was less than the original price  

Step-by-step explanation:

The original price on the computer was $1500

Discount is 25%= 0.25

Discount amount = 1500 * 0.25 = 375

Discounted price = 1500 - 375 = 1125

Now 8% shipping cost to discounted price

8% = 0.08

Shipping cost = 1125 * 0.08 = 90

cost of computer with shipping cost = 1125 + 90 = 1215

Percentage less = (original cost - cost of computer now ) / original cost

= \frac{1500- 1215}{1500}=0.19

To get percentage we multiply by 100

0.19 * 100 = 19%

Solve the equation 2/5x-1=9. Complete each step of the solution and check your solution
Fofino [41]

Answer:

x = 25

Step-by-step explanation:

2/5x - 1 = 9

Add 1 to both sides

2/5x = 10

Multiply by 5 on both sides

2x = 50

Divide by 2 on both sides

x = 25

Check the answer:

Plug in 25 for x

2/5(25) - 1 = 9

10 - 1 = 9

9 = 9

The answer is correct.
