Answer:
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.
We know that
<span>the garden's perimeter is 112 =[(x+4)+(x+4)+(x+4)+(x+4)]
112=4*[x+4]------------ > 112/4=x+4
x=(112/4)-4=28-4=24 units
the answer is x=24 units</span>
Answer:
The equation is x= (7.74 /9) 6
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.
Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.
Mathematically speaking:
x= (7.74 /9) 6
Where:
x = Cost of 6 pencils in $
Solving:
x = 0.86 x 6 = $5.16
The numbers are 10 and 7
X = 10
Y= 7
X + Y = 17
X - Y = 3
