L = W+8

P = 76 ft = 2(W) + 2(W+8) = 2W + 2W + 16 = 4W + 16.

Then 70 ft=4w, and w=70/4 = 35/2

L = W + 8 (as before).  Then L = (35/2) + 8 = 25.5 = 25 1/2 = 51/2 (answer)

x+x+(x+8)+(x+8)=76

4x+16=76

4x=60

x=15

with=15 length=23(15+8)

15+15+23+23= 76

19) Solve the system,<br> *****<br> x + 3y - 5<br> -2x + 2y = 14
faust18 [17]

Answer:

y = 3

x = -4

Step-by-step explanation:

Hopefully the first equation is x + 3y = 5

x = 5 - 3y

Plug in:

-2(5 - 3y) + 2y = 14

-10 + 6y + 2y = 14

8y = 24

y = 3

x = -4

Given the function k(t)=2t−1: a. Evaluate k(2). b. Solve(k)=7.
Aleksandr-060686 [28]

Answer:

k(2) = 3

t = 4

Step-by-step explanation:

Given

k(t) = 2t - 1

Solving (1): k(2)

Take t as 2 such that t = 2

This gives

k(2) = 2 * 2 - 1

k(2) = 4 - 1

k(2) = 3

Solving (2): k(t) = 7

Substitute 7 for k(t)

7 = 2t - 1

Add 1 to both sides

7 + 1 = 2t - 1 + 1

2t = 8

Divide both sides by 2

t = \frac{8}{2}

t = 4

A drawer contains loose socks. There are 2 blue and 4 black socks in the drawers. What is the probability that you choose a sock
stepladder [879]

The probability is p = 2/5, the correct option is the third one.

<h3>How to find the probability?</h3>

There is a total of 6 socks, such that 4 are black and 2 are blue.

Then the probability of first getting a black sock is the quotient between the number of black socks and the number of blue socks, which gives:

P = 4/6

Now there are 5 socks in total, such that 3 are black and 2 blue.

Then the probability of getting another black one is:

Q = 3/5

The joint probability (getting the two black socks) is given by the product of the individual probabilities:

p = (4/6)*(3/5) = 2/5

The correct option is the third one.
