For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
Answer: a system of linear inequations that represents the situation is: 
9mph because 20 minutes time 3 is one hour so multiply 3 by 3 to get 9
Answer:
'Twice the sum of a number and 5' can be translated into variable expression such as:
Step-by-step explanation:
Given the phrase
<em>Twice the sum of a number and 5</em>
First, let us breakdown the English Phrase
Let the number be = n
The sum of a number 'n' and 5 = n + 5
now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.
Thus,
'<em>Twice the sum of a number and 5</em>' can be translated into variable expression such as:
Answer:
<h3>The answer is option 3 </h3>
Step-by-step explanation:
4x² - 2y
when
x = - 2 and y = - 1
Substitute the values of x and y into the expression and simplify
That's
We have the final answer as
<h2>18</h2>
