What is the solution to the linear equation?

Answers

The answer is p=1

First you have to subtract 2/5 on both sides to get p=2/5x+3/5p.

Then subtract 3/5p on both sides to get 2/5p=2/5.

Then you divide by 2/5 on both sides to isolate p and you get 1 :)

(u²-4)/(u-6)(u-2)

= (u²-4)/(u²-8u+12)

= (u+2)(u-2)/(u-2)(u-6)

= u+2/u-6

The answer is A

5a³(2a)/ ab(35

= 10a^4/35ab

= 10a³/35b

= 2a³/7b

The answer is D

Sorry I don't understand the others. If you think this help is not enough please feel free to report it.

Please rate my answer.

The first one should be A since you can factor u^2-4 into (u+2)(u-2)

9.8 < 20 – 9.8t < 20

Answers

Answer:

0 < t < 1.04 or t ∈ (0, 1.04)

Step-by-step explanation:

Solving in steps:

9.8 < 20 – 9.8t < 20
9.8 - 20 < -9.8t < 20 - 20 ⇒ subtract 20 from all sides
-10.2 < -9.8t < 0 ⇒ divide all sides by -9.8, this changes inequality signs to reverse
0< t < 10.2/9.8
0 < t < 1.04 or t ∈ (0, 1.04)

Harriet wants to buy items worth $248.50. She is using a store coupon for 25 percent off her purchases. She has to pay 5 percent sales tax. Calculate the total cost of the items.

Answers

Starting price is : $248.50
Price with 25% off :
$248.50 x ( 1 - 0.25 ) = $248.50 x 0.75 = $186.375

$186.375 x 1.05 = $195.70
Answer:
The total cost of the items is $195.70.

Answer: $195.70
