for equal sign

(7x+30)=11x

30=11x-7x

30=4x

30/4=x

7.5=x

for plus sign

<u>evalute</u>

(7x+30)+11x

7x+11x+30

18x+30

factorize

(7x+30)+11x

18x+30

6(3x+5)

hope it help yuh..

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?

stiks02 [169]

Answer:

solution,

$0.5(20x - 50y + 36) - 0.25( - 100x + 40y - 12) \\ = 10x - 25y + 18 + 25x - 10y + 3 \\$

Combine the like terms:

$= 10x + 25x - 25y - 10y + 18 + 3 \\$

Simplify:

$35x - 35y + 21$

Hope this helps...

Good luck on your assignment...

How do the perimeters of the triangles compare? Original: height-18, slant-30, length-24 Scaled: height-6, slant-10, length-8 A)

SVEN [57.7K]

Answer:

D) the scaled triangles perimeter is 1/3 the size of the original triangles perimeter

Step-by-step explanation:

Given

Original:

$Height = 18, Slant = 30, Length =24$

Scaled:

$Height =6, Slant=10, Length=8$

Looking at the dimension of both triangles, The relationship between the original and the scaled copy is:

$Scaled = \frac{1}{3} * Original$

Hence, the perimeter is:

$Perimeter (Scaled) = \frac{1}{3} * Perimeter (Original)$
