If abx - 5 = 0, what is x in terms of a and b?

Answers

Answer 1

Answer: Here we want to have x on one side of equation so,
we put number 5 on right side of equation:
abx=5
then we divide both sides by ab to obtain x on left side:
Result:
x= $(5)/(ab)$

Answer 2

Answer: $abx - 5 = 0$

$abx - 5 +5= 0+5$

$abx=5$

$(abx)/(ab) = (5)/(ab)$

$x= (5)/(ab)$

Notebooks cost $1.20 each. This weekend they will be $.80 What percentage is the sale?

Andrea is shopping for items for her pet sitting business because the store is having a sale where everything in the store is 5% off. Andrea buys a cat carrier for $39.99 and a cat tower for $19.99. She has a coupon for an additional 15% off on the cat tower. Before tax, Andrea estimates that her total, after discounts, will be about $54. Determine if Andrea has estimated correctly.

Answers

Given:
cat carrier : 39.99
cat tower: 19.99
1st discount : 5%
2nd discount: 15% - cat tower

39.99 * 5% = 1.99
39.99 - 1.99 = 38

19.99 * (5% + 15%) = 19.99 * 20% = 3.99
19.99 - 3.99 = 16

38 + 16 = 54

Solve for b. -9/3 + b = -1

Answers

$-(9)/(3)$ + b = -1
Simplify $-(9)/(3)$ , which is: -3
-3 + b = -1
take -3 to the other side
-3 (+3) + b = -1 + (3)
-3 and + 3 cancels out
b = 2

Check:
$-(9)/(3)$ + (2) = -1
-3 + 2 = -1
-1 = -1

What negative numbers multiply to get a positive 54

Answers

16 would be the answer

The negative numbers that will multiply to get a positive 54 are -9 and -6.

Solve the proportion. If necessary, round to the nearest hundredth. 9/(y +1) = 18/54 *22

18

30

26

Answers

Answer: y=26

Explanation: because if 18/54 was equivalent to 9/(y+1) and 9 is half than 18 then (y+1) would have to be equal to half of 54 which is 27. So if y+1 equals 27 then y would have to equal 26!
