Simplifying
a + 5 = -5a + 5

Reorder the terms:
5 + a = -5a + 5

Reorder the terms:
5 + a = 5 + -5a

Add '-5' to each side of the equation.
5 + -5 + a = 5 + -5 + -5a

Combine like terms: 5 + -5 = 0
0 + a = 5 + -5 + -5a
a = 5 + -5 + -5a

Combine like terms: 5 + -5 = 0
a = 0 + -5a
a = -5a

Solving
a = -5a

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '5a' to each side of the equation.
a + 5a = -5a + 5a

Combine like terms: a + 5a = 6a
6a = -5a + 5a

Combine like terms: -5a + 5a = 0
6a = 0

Divide each side by '6'.
a = 0

Simplifying
a = 0

1 Cancel 5 on both sides.

a=-5aa=−5a

2 Subtract -5a−5a from both sides.

a+5a=0a+5a=0

3 Simplify a+5aa+5a to 6a6a.

6a=06a=0

4 Divide both sides by 66.

a=0a=0

------------------------------------------------------------------------------------------

a+5=-5a+5a+5=−5a+5

1 Let a=0a=0.

0+5=-5\times 0+50+5=−5×0+5

2 Simplify 5\times 05×0 to 00.

0+5=-0+50+5=−0+5

3 Simplify 0+50+5 to 55.

5=-0+55=−0+5

4 Simplify -0+5−0+5 to 55.

5=55=5

The perimeter of a triangle is 45 centimeters. find the lengths of its sides if the longest side is 7 centimeters longer than th
dangina [55]
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7

x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19

The sides are 12, 14, and 19 cm. long. Hope this helped!

A man is 5 feet 9 inches tall. To find the height of a tree, the shadow of the man and the shadow of the tree were measured. The
Rzqust [24]

Answer:

17 feets 3 inches

Step-by-step explanation:

Given :

Converting the parameters to inches only:

Recall:

1 feets = 12 inches

Man's height : 5 feets 9 inches = (12 *5) + 9 = 69 inches

Man's shadow : 3 feets 6 inches = (12 * 3) + 6 = 42 inches

Tree's shadow : 10 feets 6 inches = (12 * 10) + 6 = 126 inches

(Tree's height / tree's shadow) = (man's height / man's shadow)

Let tree's height = x

x / 126 = 69 / 42

Solve for x

42x = 126 * 69

42x = 8694

x = 8694 / 42

x = 207 inches

207 / 12 = 17 feets 3 inches

¿se puede hacer un triangulo con las siguientes medidas:2cm ,3cm ,10cm? ayudenme es para mañana
dezoksy [38]

Não, não podemos fazer um triângulo com os comprimentos dos lados de 2 cm, 3 cm e 10 cm. Isso ocorre porque a soma de 2+3 < 10. (in english: No, we cannot make a triangle with the side lengths of measurement 2 cm, 3 cm, and 10 cm. This is because sum of 2+3 < 10).

<h3>What is triangle inequality theorem?</h3>

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

(a+b) > c\\(b+c) > a\\(c+a) > b

Now, for this case, the sides given are:

  • a =2 cm,
  • b = 3 cm,
  • and c = 10 cm

But we see that:

a+ b = 5 cm which is < c which is of 10 cm.

Thus, these lengths don't satisfy the triangle inequality theorem, and therefore, cannot be sides of any triangle.
