Given
An algebraic expression is the difference between seven times a number and three times that number.
To find:
The algebraic expression.
Solution:
Let x be the unknown number.
Multiplication is used for times and subtraction is used for difference.
7 times of a number = 7x
3 times of that number = 3x
The difference between seven times a number and three times that number is
Therefore, the algebraic expression for the given statement is 7x-3x and its simplified form is 4x.
Answer:
She makes $4.66
Step-by-step explanation:
In this problem we are required to calculate the profit she makes from each bracelet
Given data
Selling price for a bracelet =$9
Cost price for a bracelet = $4.35
Profit= selling price- cost price
Profit = 9-4.35= $4.66
We can to make the method of substitution.
Look:
3x + 15y = 35
Isolating 3x
15y = 35 - 3x
Dividing both the sides by 15
y = 35/15 - 3x/15
Simpliting:
y = 7/3 - x/5
Now let's equate this expression with the other
7/3 - x/5 = - x/5 + 7/3
0 = 0
Oh noOo!
There is solution infinatly to this question!
Because, the two equation are the same.
Hope this helps!
we are given
we can also write as
Since, the base of logs are same
so, we can use property
we can use property of log
so, we get
So, we get
