Answer:
x=3
Step-by-step explanation:
First we should subtract 14 from both sides, getting 64 * 3^x = 1728. Then we can divide by 64 on both sides, leaving us with 3^x=27. x is equal to 3.
Answer:
-13 5/7 divided by -56/91 is 22 2/7
Step-by-step explanation:
By checking, (don't do it my way)
#1. 13 5/7 is 96/7 as an improper fraction.
#2 Then, make it negative.
#3 -56/91 is simplified as -8/13
#4 Divide. --> -96/7 :(-8/13)=-96/7*-13/8= -96/*(-13)/7*8=1248/56=156/7
=22 2/7
Identity
An identity is an equation that is true for all values of the variables. For example:
(x+y)^2=x^2+2xy+y^2
The above equation is true for all possible values of x and y, so it is called an identity.
Strictly speaking we should use the "three bar" sign to show it is an
identity as shown below. But it is very common to use the equal sign.
three consecutive integers
the sum of the first two integers is 24 more than the third integer.
This means that the three integers are 25, 26 and 27.
