Answer:

h = 10/3

Step-by-step explanation:

-( 6h+7) +8= -19

Subtract 8 from each side

-( 6h+7) +8 -8= -19-8

-( 6h+7) = -27

Divide by -1

( 6h+7) = 27

Subtract 7

6h +7-7 = 27-7

6h = 20

Divide by 6

6h/6 = 20/6

h = 10/3

How many times can 8 go into 60
nignag [31]

The correct answers are:

(1) If EXACT number is required, then 7.5.

(2) If multiple of 8 is required then the answer will be 7 times with a remainder of 4.

Explanation:

First you need to express it in the form of equation to make things simpler as follows:

8 * y = 60

We need to find y; to do so, divide 60 by 8:

y = \frac{60}{8}

y = 7.5

Now if you want to find the whole number, then the answer will be 7 times, with 4 left over.

The variable z varies jointly with x and y. If z = 18 when x = 2 and y = 6, find the constant of variation, k, and then find the
solniwko [45]

Answer:

The constant of variation k is 3/2.

The value of z is -30.

Step-by-step explanation:

As we know Function form is

Z=kxy-------------1

So for k  

K = z/xy

So if z=18, x=2 y=6

k= 18/2 x6

k= 18/12

k=3/2

Now we have to find for z, now we know the value of x= -4  y =5 z =3/2

z= kxy

z= 3/2  (-4)(5)

z= -30

The length of a rectangle is three times its width. If the perimeter is at most 112 centimeters, what is its greatest possible v
Nana76 [90]

Answer:

Step-by-step explanation:

Perimeter= 2L+2W. If L=3W(three times the width) then 2(3W)+2W=112. Or 6W+2W=112 which is equal to 8W=112. To solve for the width, divide both sides by 8 and find 112/8=14, therefore W=14.
