2x+1 = x-5
-x -x
X+1 = -5
-1 -1
X = -6
2(-6) +1= y
-12+1= y
-11 = y
-11 = -12+1
-11 = -6-5
GCF stands for "greatest common factor". This means what is the largest quantity you can divide into 6x and 20xyz without a remainder. First see what is the biggest number you can divide 6 by and also 20 without having a remainder. Next, you should see which variables 6x and 20xyz have in common. variables are the (x,y, and z). Put these two values togther and this will be your GCF.
Answer:
40 ways
Step-by-step explanation:
Step one:
given data
number of people= 6
number of committees=6
Required
The number of ways the committees can be formed differently
Step two:
Applying the combination formula we have
C(n,r)= n!/(n-r)r!
substitute
C(n,r)= 6!/(6-3)3!
C(n,r)= 6*5*4*3!/3*3!
C(n,r)= 6*5*4/3
C(n,r)= 120
/3
C(n,r)= 40 ways
Answer:
65x+91y+104
Step-by-step explanation:
13(5x + 7y + 8)
Distribute
12*5x +13*7y+13*8
65x+91y+104
Answer:
y = 360
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = 
← k is the constant of proportion
To find k use the condition y = 10 when x = 3 , then
10 = 
= 
( multiply both sides by 9 )
90 = k
y = 
← equation of proportion
When x = 
, then
y = 
= 
= 90 × 4 = 360
