The sum of two numbers is 12. the difference of the same two numbers is -4 . find the two numbers

gtnhenbr [62]

Answer:

(4,8)

x=4

y=8

Step-by-step explanation:

x is the first number

y is the second number

x+y=12

x-y= -4

Let's add y and 4 to the second equation to get y by itself

x+4=y

We can substitute this value in for y in the first equation

x+x+4=12

2x=8

x=4

We can then use x=4 and plug that into any equation

4+y=12

y=8

The answer is (4,8)

The area of a triangle is 1/2 of base times height
for ΔPQS, the base is PS=6, the area is 16.5, so the height is 16.5×2÷=5.5
the height of the triangles is also the height of the trapezoid.

Sonja [21]

Answer:

The correct answer is that a possible value for n could be all numbers from 101 to 120.

Step-by-step explanation:

Ok, to solve this problem:

You have that: $10$

Then, applying the properties of inequations, the power is raised by 2 on both sides of the inequation:

$(10)^{2}$

$100$

Then, a possible value for n could be all numbers from 101 to 120.
