Answer:

Number = -1/2

Step-by-step explanation:

Let the number = x

Now

According to given conditions:

8x + 6 = 2

Subtracting 6 from both sides we get:

8x + 6 - 6 = 2 - 6

8x = -4

Dividing both sides by 8 we get:

x = -4/8

Reducing to lowest form:

x = -1/2

Proof:

8(-1/2) + 6 =2

-8/2 +6 =2

-4 + 6 =2

2 = 2

Hence proved

I hope it will help you !

larisa [96]
Y+x=98
y-x=22

I'm going to use elimination. 

y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60. 

Substitute that into either equation and you get y=60 and x=38

Have a nice day! :)

larisa86 [58]

Answer:

688.7

Step-by-step explanation:

Top and Bottom

Area = 3/4 * pi * r^2

r = 6

Area = 3/4 * 3.14 * 6^2

Area =                                                               84.78

Don't round yet.

Vertical surface

Vertical surface = 3/4 * pi * d * h

d = 12 inches (the diameter)

Vertical surface = 3/4 * 3.14 * 12 * 15

Vertical surface =                                          423.9

Two inner faces

They are both rectangles

Area = 2 * L * W

L = 15

w=6

Area = 2 * 15 * 6                           <u>                  180</u>

Total                                                               688.68

Total = 688.7

Ainat [17]

Answer:

\Huge\boxed{z

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25
