Let the length of the base of this isosceles triangle be = x

One of its equal sides = 3x

Another one of its equal sides = 3x

Their perimeter = x + 3x + 3x = 21 cm

To find the value of each side let us first solve this equation .

= x + 3x + 3x = 21 cm

= 7x = 21 cm

= x = 21 ÷ 7 ( transposing ×7 from LHS to RHS changes ×7 to ÷7 )

= x = 3

Then length of base = 3 cm

Length of one equal side = 3 × 3 = 9 cm

Length of another equal side = 3 × 3 = 9 cm

Therefore , the the three sides of this triangle = 3 cm , 9 cm and 9cm .

Expand: 9 - 15 +12x

Simplify: -6 + 12x

-6 (1 - 2x)

The solution of the given expression 9-3(5-4x) is -6 (1 - 2x).

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 9-3(5-4x). The expression will be simplified as:-

E = 9 - 15 +12x

E = -6 + 12x

E = -6 (1 - 2x)

Therefore, the solution of the given expression 9-3(5-4x) is -6 (1 - 2x).

Answer:

[tex]Giraffe:Others = 3:7[/tex]

Step-by-step explanation:

See Attachment for complete question

For this question, we only need the data at the Congtin column.

So, we have:

[tex]Giraffes = 124[/tex]

[tex]Other = 108[/tex]

First, we need to reduce Giraffe by 63%.

This gives:

[tex]New\ Giraffe = Giraffe - 63\% * Giraffe[/tex]

[tex]New\ Giraffe = 124 - 63\% * 124[/tex]

[tex]New\ Giraffe = 124 - 78.12[/tex]

[tex]New\ Giraffe = 45.88[/tex]

Represent this as a ratio:

[tex]Giraffe:Others = 45.88:108[/tex]

The closest to this ratio is 3:7.

This is shown by dividing the ratio by 15

i.e.

[tex]Giraffe:Others = 45.88/15:108/15[/tex]

[tex]Giraffe:Others = 3.0589:7.2[/tex]

Approximate:

[tex]Giraffe:Others = 3:7[/tex]

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

We have to create 2 fractions with the repeating number placed after the decimal point.

let x = 0.88.... → (1) ( multiply both sides by 10 )

10x = 8.88.... → (2)

Subtract (1) from (2), eliminating the repeating decimal

9x = 8 ( divide both sides by 9 )

x = [tex]\frac{8}{9}[/tex]

Thus 0.888..... = [tex]\frac{8}{9}[/tex]

Well, we know that it costs $60 plus 5 per month for Alpha Fitness Club.

We also know that it costs $20 plus 10 per month for Omega Fitness Club.

In order to find out which one would cost the most, we must add the additional costs to the original join cost.

(NEVER add the join cost, just do the join cost at the beginning or else the clubs will never become the same cost.)

Club      M1  M2  M3  M4  M5  M6  M7  M8  M9

Alpha:   60   65  70   75   80   85   90  95  100

Omega:20   30  40   50   60   70   80  90  100

If you look above, you realize that there is a time when they both cost the same.

Summary sentence:

After 9 months, the cost to belong to either fitness club would be $100.

Answer:

5(10) + 5(7) = 85

Step-by-step explanation:

The true statement about the given triangle figure is B and C.

The triangle has the following characteristics: All triangles, regardless of kind, have an angle total of 180 degrees. The length of a triangle's two longest sides added together is longer than the third side. Similarly to this, the length of the third side of a triangle third side is shorter than the difference between its two sides.

Given a triangle, where m∠4 is an outer angle. from the properties of the outer angle of the triangle, Each Exterior angle = 180° - Interior angle. This formula can be used if the corresponding interior angle is given. Exterior angle = Sum of Interior opposite angles. The sum of all the exterior angles of a triangle is 360°.

Therefore, only option B and C which is m∠4 = m∠1 + m∠2 and m∠4 = 180 − m∠3 respectively are true statements about the given triangle.

Answer:

  a) (146 +135 +(p-8) +p)/4 = 135

  b) 3rd game: 125.5; 4th game: 133.5

Step-by-step explanation:

The average score is the sum of scores divided by the number of games.

We are told the 4th game score is p, and the third game score is p-8. So, the scores in the four games are ...

  146, 135, p-8, p

__

a) Their average is 135, so we have ...

  (146 +135 +(p-8) +p)/4 = 135 . . game average

__

b) Solving the equation, we get ...

  273 +2p = 540 . . . . . . . . . . . . . multiply by 4, collect terms

  2p = 267 . . . . . . . . . . . . . . . . . .  subtract 273

  p = 133.5 . . . . . . divide by 2

Then the third game score is p-8 = 133.5-8 = 125.5, and the fourth game score is 133.5

Pavan's scores in the 3rd and 4th games were 125.5 and 133.5, respectively.
