Answer:

1/4w -1

Step-by-step explanation:

(1/2w +3) -(1/4w +4) = w(1/2 -1/4) +(3 -4)

= 1/4w -1

_____

The distributive property applies. It is useful for distributing the minus sign and for collecting terms.

The eqaution for this question would be:

(1/2w+3) - (1/4w+4)

For the first step we need to take away the brackers:

1/2w + 3 - 1/4w - 4

We can then group the unknown and the other values together :

1/2w - 1/4w +3 -4
= (1/2 - 1/4)w +3 -4

We can then proceed to calculate the answer:

(1×2/2×2 - 1/4)w -1
=(2/4-1/4)w -1
= 1/4w - 1

Therefore the answer is 1/4w - 1.

Hope it helps!

Hunter-Best [27]

Answer:

x = 28.60 feet

Step-by-step explanation:

We are given a height of 2 feet above the ground and the angle of elevation of 86 degrees.

Now, let's assume that the form of our problem is in the form of a right triangle, we can solve for the remaining angle as follows;

180 - (90+86) = 4 degrees

The distance from the home plate to the centerfield is been calculated below as

2/sin 4 = x / sin 86

solving for x we have

x = 28.60 feet

We have 28.60 feet as our answer

mezya [45]

Answer: 1/5, 1/2, 0.

Step-by-step explanation:

given data:

no of cameras = 6

no of cameras defective = 3

no of cameras selected = 2

Let p(t):=P(X=t)

p(2)=m/n,

m=binomial(3,2)=3!/2!= 3

n=binomial(6,2)=6!/2!/4! = 15

p(3)= 3/15

= 1/5.

p(1)=m/n,

m=binomial(6,1)*binomial(2,2)=6!/1!/4!*2!/2!/0!= 7.5

n=binomial(6,2)= 15

p(2)= 7.5/15

= 1/2

p(0)=m/n,

m=0

p(0)=0

Here is the complete question: 40% of the memberships sold by Gym A were gold memberships. 25% of the memberships sold by Gym B were gold memberships.

Which statement must be true?

a) If both gyms sold 80 total memberships, Gym A sold 12 more gold membership.

b) If both gyms sold the same number of memberships, Gym A sold 15 more gold membership.

c) Gym A sold more gold membership than Gym A did.

d) If Gym B sold 50 membership, 25 would be gold memberships.

Given: Gym A have sold 40% gold membership of total membership.

Gym B have sold 25% gold membership of total membership.

Lets take option A first to find if it is true statement.

As per option A, There are total number of membership is 80.

∵ Gym A has sold 40% gold membership.

∴ Gym A gold membership= $40\% \times 80$
