2/3z = -4


Z= ?

Answers

Answer:

z=(-6)

Step-by-step explanation:

(2/3)*z=(-4)

2*z=3*(-4) --> We move the 3 from the left to the right part of the equation. It was dividing, so we move it multiplying.

2*z=(-12)

z=(-12)/2 --> It's the inverse case of before. 2 was multiplying, so we move it to the right by dividing it.

z=(-6)

Tyler makes a sign that is 79 yard long and 23 yard wide. What is the area of his sign in square yards?

Answers

Answer:

[tex]A=1817\ \text{yards}^2[/tex]

Step-by-step explanation:

Given that,

The length of sign, l = 79 yard

Width, b = 23 yards

We need to find the area of his sign. It is in the form of a rectangle. The area of a rectangular shape is given by :

[tex]A=l\times b\\\\A=79\times 23\\\\A=1817\ \text{yards}^2[/tex]

So, the area of his sign is [tex]1817\ \text{yards}^2[/tex].

Answer:

c. 243 ft^2

Step-by-step explanation:

where l = length

w= width

given; l= w+18

perimeter= 2(l+w)

72= 2(l+w)

72/2 = l+w

36= l+w

36= (w+18) +w

36= w+w+18

36= 2w +18

36-18=2w

18=2w

18/2=w

w=9ft

l=w+18

l=9+18= 27ft

Area = l×w

= 27×9 = 243ft^2

If 1 inch = 2.54cm, then set up and solve a proportion that finds how many inches, n, there are in 10 cm. (Round your answer to the nearest tenth)

Answers

Given:

1 inch = 2.54 cm

To find:

The number of inches, n, in 10 cm.

Solution:

We have,

1 inch = 2.54 cm

On dividing both sides by 2.54, we get

[tex]\dfrac{1}{2.54}[/tex] inch = 1 cm

On multiplying both sides by 10, we get

[tex]\dfrac{1}{2.54}\times 10[/tex] inch = 10 cm

Now, number of inches n in 10 cm is

[tex]n=\dfrac{1}{2.54}\times 10[/tex]

[tex]n=3.93700787402[/tex]

[tex]n\approx 3.9[/tex]

Therefore, the number of inches in 10 cm is 3.9.
