Philip is 5 years old and Jon is 19 years old now.

Step-by-step explanation:

Step 1 :

Let x be the age of Philip Now

Since Jon is 14 years older than Philip,

Age of Jon = 14 + x

Step 2 :

After  2 years,

Age of Philip = x+ 2

Age of Jon = 14+x+2 = 16+x

Step 3 :

Given that in 2 years, Jon will be 3 times as old as Philip.

So we have 16 + x =3(x+2)

=> 16 + x = 3x +6

=> 2x = 10 = x = 5

Hence age of Philip is 5 years

Age of jon = x + 14 = 5+ 14 =19 years

The sum of two numbers is -17 and their difference is 41 what are the two numbers?
liberstina [14]

Answer: the two numbers are 7 and -27

Step-by-step explanation:

Let the two numbers be a and b

From the question,

a + b = -27.......eqn 1

a - b = 41............eqn 2

Sum the two equations

2a = 14

Divide both sides by 2

a = 14/2; a = 7

Substitute a = 7 into equation 2

a - b = 41

7 - b = 41

Make b the subject of the equation

-b = 41 -7

-b = 34

b = -34

Check:

a + b = -27, slot the values of a and b

7 + (-34) = -27

7- 34 = -27

I hope this is clear, please mark as brainliest answer

A rectangular pan has a length that is the width. The total area of the pan is 432 in.2. What is the width of the cake pan? A =
spayn [35]

Answer:

Let width = w

length = 4w/3

Area = 432 = length*width = w*4w/3

4w^2/3 = 432

w^2 = 432*3/4 = 324

w = 18

so the width of the cake pan is 18 inches.

Simplify the following expression 6X2 plus 8X -3 minus 3X2-6
Murrr4er [49]

Answer:

-24

Step-by-step explanation:

I´m guessing by the big x sign you want me to multiply so the first step in the equation is to multiply because of PEMDAS so(6*2)+(8*-3)-3*2-6,

so 6*2=12,8*-3=-24,-3*2=-6

12+-24-6-6,

12-24=-12,-6+-6=-12

-12+-12=-24
