Answer:

$124 higher
Step-by-step explanation:
Given


Required
Represent the situation
Determine how much higher or lower is the remaining amount
Let the initial amount in his account be represented with x
When he deposited, the balance becomes

When he withdrew, the balance becomes

Hence, the algebraic expression is

Calculating how much higher or lower

Open bracket


Recall that the initial amount in the account is x
The difference between the balance and the x is as follows


<em>Hence, the account has a higher of $124 after both transactions</em>
The 3rd one because of the laws and newton’s ways
Answer:
x = 20
Step-by-step explanation:
The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is
4x + 2 + x + 78 = 180
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Answer:
7^18
Step-by-step explanation:
When you have an exponent to another exponent, you can multiply the exponents.
(7^3)^6
3*6 = 18
7^18
