You don't say <em>how many</em> numbers you want to do that with.

If you want just two numbers, then they're  <em>+7.3107</em>  and  <em>-12.3107</em> .
(Those are rounded, not exact.)

I took a quick look among the factors of 90, looking for sets of <em>3 numbers</em>
that would do it, and I couldn't find any.

Let
x-------> the first number
y-------> the second number

we know that

x+y=-5 \\ x=-5-y equation 1

x*y=-90 equation 2

substitute the equation 1 in equation 2

[-5-y]*y=-90 \\ -5y- y^{2} =-90 \\ y^{2} +5y-90=0

using a graphical tool to resolve the second order equation
see the attached figure
the numbers are
-12.311
7.311

Barb solved the following equation: 4(3x – 12) = 5(2x + 6)
katrin2010 [14]

Answer:

4(3 * 39 – 12) = 5(2 * 39 + 6)

x = 39


Step-by-step explanation:

4(3x – 12) = 5(2x + 6)

(12x - 48) = (10x + 30)

12x - 10x = 30 + 48

2x = 78

2x/2 = x

78/2 = 39

x = 39

No Prob :)

For the following right triangle, find the side length of x. round your answer to the nearest hundredth.
tatyana61 [14]

Answer:

14.87 units

Step-by-step explanation:

The sides of all right triangles share the same relationship known as the Pythagorean Theorem a² + b² = c². Substitute the lengths of the triangle into the theorem and solve for the unknown side. Since the problem does have an attached a picture, assume that a = 10, b = 11, and c = x.

10² + 11² = x²

100 + 121 = 221²

221 = x²

√221 = √x²

14.87 = x

-10 x + 4 = 52 x=___ help
Strike441 [17]

Answer: x=-4.8

Step-by-step explanation:

Given

-10x+4=52

Subtract 4 on both sides

-10x+4-4=52-4

-10x=48

Divide -10 on both sides

-10x/-10=48/-10

x=-4.8

Hope this helps!! :)
