Answer:
y=6,5,4,3 are value for y
Answer:
1/20
Step-by-step explanation:
(1/4) / 5
When dividing a fraction by a whole number

(1/4) / 5 = 1/20
Answer:
<em><u>The number of students that like only Nokia </u></em>
<h2>= 30</h2>
Step-by-step explanation:
consider N the number of students who like Nokia → N=?
T the number of students who like Techno → T=35
Statement 1: In a class of 40 students, 5 like neither Nokia nor Techno
we can translate it like this: 35 student like Nokia or Techno
we can note it like this : T∪N= 35
Statement 2: 30 like Techno and Nokia
we can note it : T∩N = 30
using a rule concerning the number of element of a set :
T∪N = N + T - T∩N
then
35 = N + 35 - 30
⇒ N - 30 = 0
⇒ N = 30
Answer:
If the sum is 6, a small cone will be ordered
If the sum is 8 or 9, a medium cone will be ordered.
If the sum is 11, a large cone will be ordered.
Step-by-step explanation:
If the sum is 6, a small cone will be ordered
If the sum is 8 or 9, a medium cone will be ordered.
If the sum is 11, a large cone will be ordered.
The description above accurately explains how a fair decision can be made in this situation. Because the least sum of value = 6
While the highest sum of value of number = 11.
Answer: x=3 and y=4
Step-by-step explanation:
x+y=7;x+2y=11
Step: Solvex+y=7for x:
x+y=7
x+y+−y=7+−y(Add -y to both sides)
x=−y+7
Step: Substitute−y+7forxinx+2y=11:
x+2y=11
−y+7+2y=11
y+7=11(Simplify both sides of the equation)
y+7+−7=11+−7(Add -7 to both sides)
y=4
Step: Substitute4foryinx=−y+7:
x=−y+7
x=−4+7
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=4
