Which number is irrational?<br><br> A.0.3  B. C.0.777... D.0.454545…
Savatey [412]
Each of A, C, and D are rational, so presumably B is the answer here.

A is rational, since 10\times0.3=3, so 0.3=\dfrac3{10}.

C is also rational. If x=0.777\ldots, then 10x=7.777\ldots. This would mean 10x-x=9x=7, and so x=\dfrac79.

D is rational by a similar argument. If x=0.4545\ldots, then 100x=45.4545\ldots. So, 100x-x=99x=45, which means x=\dfrac{45}{99}=\dfrac5{11}.

Aaron is 15 centimeters taller than Peter, and five times Aaron's height exceeds two times Peter's height by 525 centimeters. Th
Tatiana [17]
The system of linear equations that relates x and y:
x= 15 + y
5 x = 2 y+ 525
We will solve this system using substitution method:
5(15 + y)=2 y + 525
75 + 5 y = 2 y + 525
5 y - 2 y = 525 - 75
3 y = 450,           y = 450 : 3        y = 150
x = 15 + y           x = 15 + 150     x = 165
Answer: Aaron´s height is 165 cm and Peter´s height is 150 cm.

Simplify these expressions
makkiz [27]

Answer:

4) 7a+20

5) 14+2b

6) 25c² - 15

Step-by-step explanation:

4) 9a+7-2a+13= 9a-2a+7+13 = 7a+20

5) 21-3b+5b-7= 21-7+5b-3b = 14+2b

6) (3c)² + (8c)² - 15 = 9c² + 16c² - 15 = 25c² - 15
