Answer: 14

Step-by-step explanation:

Okay so it asks in all, which means morning distance + afternoon distance

We got the afternoon distance so now we have to find the morning one

it says the afternoon distance (6), is 25% less than the morning distance.

Which means the afternoon distance is 0.75 of the morning distance.

so 0.75x = 6, x = 6/0.75 = 8

Then you add 8 to 6 to get 14

Simplify the Expression. [4 + (-8)] x (-7) A.) -84 B.) -28 C.) 28 D.) 84

Helen [10]

C. 28 is the answer
Staring from the brackets we have 4+(-8) we can open the parentheses and get 4-8 and get -4. Now we can open the -7 up and now we have
-4 * -7 = 28
Hope this helps!

The length of a picture is 15.75 inches shorter than twice the width. If the perimeter of the picture is 106.5 inches, find its

Vladimir79 [104]

Answer:

Length = 45.37 in

Width = 30.56 in

Step-by-step explanation:

Let the width of the picture be 'w' inches.

Given:

Perimeter of the picture is, $P=106.5\ in$

Length is 15.75 inches shorter than twice the width. So, length is:

$l=2w-15.75$

Now, we know that the perimeter of a rectangular shape is given as the sum of all of its side. So, the picture is also of rectangular shape and hence the perimeter is given as:

$P=2l+2w$

Plug in the values of 'l' and 'P' and solve for 'w'. This gives,

$106.5=2w-15.75+2w\\106.5=4w-15.75\\106.5+15.75=4w\\4w=122.25\\w=\frac{122.25}{4}=30.56\ in$

Therefore, the width of the rectangular picture is 30.56 inches.

Length of the picture is, $l=2(30.56)-15.75=61.12-15.75=45.37\ in$

So, length of the picture is 45.37 inches and width is 30.56 inches.

Inscribed angle Help please

Dafna11 [192]

Answer:

x = 3

Step-by-step explanation:

The measure of the inscribed angle is half of measure of the intercepted arc .

Find the half of 192.

192/2 = 96

The inscribed angle is 96°.

Create an equation and solve for x.

31x + 3 = 96

31x + 3 - 3 = 96 - 3

31X = 93

31x/31 = 93/31

x = 3
