We can solve this system of equation by reduction method.
  d+e=15
 -d+e=-5
-------------------
      2e=10   ⇒e=10/2=5

-(d+e=15)
 -d+e=-5
-----------------
  -2d=-20   ⇒d=-20/-2=10

therefore: d=10; e=5

Answer: d.(10,5)

HLP WILL GIVE BRAINLIEST PROMISE!
Ivanshal [37]

Answer:

It'd be C?

Step-by-step explanation:

Well, if you turn 5/2 into a mixed number, it will be 2 1/2, and if you add 2 1/2 to 3, it would be 5 1/2, and C is the only one that shows it. Not only that, you could probably find out with common sense, because there is no subtracting in this problem, but every other answer besides C is subtracting.

Hope this helps

Bit late though lol

The base of the pyramid is a square what is the surface area if the pyramids height is 4 feet in the area of the base is 36 ft.?
KATRIN_1 [288]

Answer:

96 ft²

Step-by-step explanation:

The general formula for the surface area of a pyramid is:  

SA = \frac{1}{2}pl + B, were p = the perimeter of the base, l = the slant height and B = the area of the base

Since the area of the base is 36 ft², then each side is √36, or 6 ft. The perimeter is the sum of all the sides, so 6 x 4 = 24 ft.

Given the overall height of the pyramid is 4 feet, you can use the Pythagorean Theorem (a² + b² = c²) to find the slant height (hypotenuse) of the pyramid.  Using 3 feet for 'a' and 4 feet for 'b':

3² + 4² = c² or 9 + 16 = 25

25 = c² or c = 5

SA =  \frac{1}{2}(24)(5) + 36

SA = 60 + 36 = 96 ft²
