Marco has ( d + 14.55 ) $
Step-by-step explanation:
Marco's mom gave him d dollars for his allowance one week.
Allowance of one week = d $
He also earned $ 1 4 . 5 5 for his newspaper route that week.
Earning of Marco by selling newspaper route that week = 14.55 $
Total earning = Allowance of one week + Earning of Marco by selling newspaper route that week
Total earning = ( d + 14.55 ) $
So Marco has ( d + 14.55 ) $
Answer:
1) Option A) is correct
The given rational exponent expression is not simplified correctly as a radical expression is
![x^{\frac{7}{4}}=\sqrt[7]{x^4}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B7%7D%7B4%7D%7D%3D%5Csqrt%5B7%5D%7Bx%5E4%7D)
2)Option A) is correct
That is 
Step-by-step explanation:
1) Given that 
![x^{\frac{7}{4}}=\sqrt[4]{x^7}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B7%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7Bx%5E7%7D)
is the correct answer but in the given problem they gave the RHS as wrong.
Therefore the given rational exponent expression is not simplified correctly as a radical expression is
2)Given that the rational exponent expression is 
To find it as a radical expression:
Therefore
Therefore Option A) is correct
That is
Answer:
42
Step-by-step explanation:
Because of its shape I would imagine another flipped so it makes a square then solve for the square the divide.
7 x 12 =84
84÷2=42
Answer:
B
Step-by-step explanation:
1. In order to determine the inequality, you must first solve the solution set to determine what x is less than.
So you would do this:
1 + 2x < 9 Subtract 1
2x < 8 Divide by 2
x < 4
2. Next, you need to understand the difference between an open circle and a closed circle shown on the solution sets.
An open circle is equal to the following inequalities:
<, >
A Closed circle represents inequalities in situations such as:
greater than or equal to, or less than or equal to
3. Because the inequality above represents only less than or greater than the inequality sets should have an open circle being used.
Since x is less than 4 it should be moving to the left of the line inequality set.
