5 less than 4 times another. product is 6. find the integers​

Answers

y= 4x-5

x.y = 6

x = 6/y

substitute value

y= 24/y-5

y²+5y-24=0

y²+8y-3y-24=0

y(y+8) -3(y+8) = 0

y=3 or y = -8

consider y = 3,

3 = 4x-5

x= 2!

now y = -8

-8= 4x-5

x= -3/4

The answer is 2 and 3 Or -8 and -3/4

2 is not 5 less 4 times other so the solution is -8 and -3/4

Bob earns $60,000 a year at an accounting firm. Each year, he receives a raise.

Bob wonders if he should take the new job or take his chances with his current jo

Answers

Answer:

He should keep his job.

Step-by-step explanation:

We know that there is a 70% chance that he willend up getting a 10% raise. A 10% raise will allow him to make 66000 dolllars, which is 1000 more than getting a new job.

There is a 30% chance that he will make about 3,100 dollars less than a new job. However, 30% is much lower than 70%, so this probably wont be the outcome. And over future years, if this remains constant, he will end up still making more money staying wiht his job.

A square originally starts with an area of 64 cm2.
If each side of the square is increased by 2 cm, what is the area of the new square?

Answers

Answer:

100 cm2

Step-by-step explanation:

If the area is 64 cm2 that means that the side is 8 cm (square root of 64 is 8)

8 increased by 2 = 10

area 10x10 = 100 cm2

Answer:

the answer is 100cm²

since originally is 64 cm²

so square root of 64 is 8 cm.

after you get 8cm you get,

8+2 = 10cm (a side of square)

and then to find a new area you get,

10 × 10 = 100 cm²

A gymnasium floor is being covered by square shock-absorbing tiles. The new tiles are 2 inches larger in length and width than the old tiles. The new flooring will require only 600 tiles. What is the length of a side of one of the new shock-absorbing tiles

Answers

This question is incomplete, the complete question is;

A gymnasium floor is being covered by square shock-absorbing tiles.

The old gym floor required 864 square tiles. The new tiles are 2 inches larger in length and width than the old tiles. The new flooring will require only 600 tiles. What is the length of a side of one of the new shock-absorbing tiles  

Answer:

Length of the side of one of the new shock-absorbing tiles is 12 inches

Step-by-step explanation:

Given the data in the question;

Since both the area for old tiles and new tiles are the same;

so Area of old tiles = Area of new tiles,

given that; The old gym floor required 864 square tiles and new flooring will require only 600 tiles as new tiles are 2 inches larger in length and width than the old tiles.

Now let the length of the sides of the square tiles be x

Area of a square = length × length = x × x = x²

So, Area of Old tiles = 864 × x² = 864x²

Area of New tiles = 600( x + 2 )²

= 600( x² + 4x + 4 )

= 600x² + 2400x + 2400

Now, Area of old tiles = Area of new tiles

864x² - 600x² - 2400x - 2400 = 0

264x² - 2400x - 2400 = 0

we find x

Using; x = [-b ±√( b² - 4ac )] / 2a

x = [-( -2400) ±√( (-2400)² - (4 × 264 × -2400 )] / 2( 264 )

x = [ 2400 ±√( 5760000 + 2534400) ] / 528

x = [ 2400 ±√8294400 ] / 528

x = [ 2400 ±2880 ] / 528

x = [ 2400 - 2880 ] / 528  or  [ 2400 + 2880 ] / 528

x = [ -480 / 528 ] or  [ 5280 / 528 ]

x = [ -0.909 ] or  [ 10 ]

the length of the sides of the square tiles cannot be Negative

Hence, x = 10

Therefore, the length of a side of one of the new shock-absorbing tiles will be;

⇒ x + 2 = 10 + 2 = 12 inches

Length of the side of one of the new shock-absorbing tiles is 12 inches

Answers

Answer:

p = -5

Step-by-step explanation:

7(p + 1) = 2(3p + 1)

Distribute on both sides.

7p + 7 = 6p + 2

Subtract 6p from both sides.

p + 7 = 2

Subtract 7 from both sides.

p = -5

Answer:

p = -5

Step-by-step explanation:

7(p + 1) = 2(3p + 1)

Distribute

7p +7 = 6p +2

Subtract 6p from each side

7p +7 -6p = 6p+2-6p

p+7 = 2

Subtract 7 from each side p+7-7 =2-7
