is the inequality that represents this situation
<em><u>Solution:</u></em>
Given that sum of two numbers is no more than 28
Let "x" represent the first number
Let "y" represent the second number
<em><u>To find: Inequality that represents this situation</u></em>
Sum of two numbers means we have to add "x" and "y"
Sum of two numbers is no more than 28
Here, "no more than 28" , means that not greater than 28
It can be less than or equal to 28
Thus we frame a inequality as,
Thus the required inequality is found
Answer:
N-12 = 20
N=32
Step-by-step explanation:
Difference means subtract, is means equals
N-12 = 20
Add 12 to each side
N-12+12 =20+12
N = 32
Answer:
The answer is 120
Step-by-step explanation:
Answer:
C = $2.40
n = 6
Step-by-step explanation:
For Noelle,
Equation that represents the monthly cost 'C',
C = 0.2n + 1.20
Here, n = number of checks written in a month
For Micah,
Monthly cost for writing checks 'C' = $1.20
Number of checks 'n' = 3
Since, Cost of writing checks ∝ Number of checks written
C' ∝ n
C' = kn
k =
Here, k = proportionality constant
For C' = 1.2 and n = 3
k =
k = 0.4
Equation will be,
C' = 0.4n
For any month C = C'
Therefore, 0.2n + 1.20 = 0.4n
0.4n - 0.2n = 1.20
0.2n = 1.20
n = 6
Number of checks written by Noelle and Micah = 6
For n = 6,
C = 0.2(6) + 1.20
C = $2.40
Cost of writing checks = $2.40
The value of x is 5
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions made up;
- Factors
- variables
- terms
- constants
They also consist of mathematical operations such as addition, multiplication, division, subtraction, parenthesis, brackets, etc
We have the expression as;
7.5x = 5.5x + 10
collect like terms
7.5x - 5.5x = 10
subtract the like terms
2.0x = 10
Make 'x' the subject
x = 10/2. 0
x = 5
Thus, the value of x is 5
