Answer:
x= 3/4 or 0.75
Step-by-step explanation:
multiply by 7
-7x+3= 14x-25
3=21x-25
28=21x
x=3/4
Answer:
C (20,5)
Step-by-step explanation:
The committees should contain 5 persons each
The number of people are 20
Apply combination concept
where
²⁰₅C = 20! /[ {20-5}!*5! ]
=20! / 15!*5!
=15504 ------The number of 5 person committees that could be formed from a group of 20 people.
First, find the GCF. For these two numbers, it is 36. (Because 36 times 1 is 36 and 36 times 2 is 72)
Divide both sides by this, which gives you a
2:1 ratio
Answer:
No solution
Step-by-step explanation:
Step 1: Write out equations
y = -1/4x + 2
3y = -3/4x - 6
Step 2: Substitution
3(-1/4x + 2) = -3/4x - 6
Step 3: Distribute
-3/4x + 6 = -3/4x - 6
From here, we can see that we have the same slope but different y-intercept. This means that the 2 lines are parallel and therefore never intersect.
Alternatively, you could graph the equations and see that the 2 lines are parallel and never intersect.
