Answer:

  each equation can be transformed to the other

Step-by-step explanation:

Starting with the given equation, we can subtract 4, then multiply by 2:

  x + 5 = 15

  x + 5 - 4 = 15 - 4

  x + 1 = 11

  2(x + 1) = 2(11)

  2(x +1) = 22 . . . an equivalent equation

The properties of equality allow one equation to be transformed into the other.

Calculate the missing value. (Not drawn to scale.)
True [87]

Answer:5in

Step-by-step explanation:

1. Identify the triangle

you are given a right triangle with the hypotonus missing and are given the side lengths 3 and 4 you know the hypotonus is 5 by the 3,4,5 Pythagorean tripe, if you do not notice this it can be solved with the Pythagorean theorem a^2+b^2=c^2

2. solve (if not done with 3,4,5 triple)

3^2+4^2=c^2

9+16=c^2

25=c^2

5=c | square root both sides to cancel the square

A cat spends about 7 out of 10 hours sleeping about what percent of a cat's day is spent sleeping
hram777 [196]
I understand that it means that out of every 10 hours, a cat spends 7 sleeping (not 7 hours in a day).


this means that a cat is sleeping\frac{7}{10}*100%=70%

a percentage stays constant, this means that a cat sleeps 70 % of each 10 hours, but also 70% of the day.
