−8=x+11/−2

Step 1: Simplify both sides of the equation.

−8=x+−11/2

Step 2: Flip the equation.

x+−11/2=−8

Step 3: Add 11/2 to both sides.

x+−11/2+11/2=−8+11/2

x=−5/2

Answer:

x=−5/2

Which of the following is the solution to the compound inequality below? 3/2x+1/5≥-1 or -1/2 x-7/3≥ 5
borishaifa [10]

\frac{3}{2}x + \frac{1}{5} \geq -1

(10)\frac{3}{2}x +(10) \frac{1}{5} \geq -1(10)  

15x + 2 ≥ -10

<u>        -2  </u>   <u> -2  </u>

     15x ≥ -12

      \frac{15x}{15} \geq \frac{-12}{15}

         x ≥ \frac{-12}{15}

         x ≥ \frac{-4}{5}

OR

-\frac{1}{2} x - \frac{7}{3} \geq 5

-(6)\frac{1}{2} x - (6)\frac{7}{3} \geq 5(6)

-3x - 14 ≥ 30

<u>      +14</u>    <u>+14 </u>

     -3x ≥ 44

       \frac{-3x}{-3} \leq \frac{44}{-3}

       x \leq -\frac{44}{3}        

Graph:  ←--------  -\frac{44}{3}      \frac{-4}{5} ----------→

Interval Notation: (-∞, -\frac{44}{3}] U [\frac{-4}{5}, ∞)

What two ways can you find the product of 8x997 using mental math
ss7ja [257]
8=10-2 or
997=1000-3
so we can use distributive property
remember, a(b+c)=ab+ac

for the first one
8(997)=(10-2)(997)=997(10-2)=997(10)+997(-2)=9970-1994=7976

2nd one
8(997)=8(1000-3)=8(1000)+8(-3)=8000-24=7976

C. If one cubic foot contains about 7.5 gallons, how many gallons of water are in the pool? (3 points) I Water: gallons 3. A rec
Dominik [7]

Answer:

<u>One Rectangular Pan</u>

Step-by-step explanation:

Part C cannot be answered since the dimensions of the pool are not given.  Please check the question.

The cake pans may be compared by calculating the volume of each shape:

Rectangular pan:  Volume = Length x Width x Height

  Volume Rectangle = (13")*(9")*(2") = <u>234 in^3</u>

Round pan:  Volume = \pi r^{2} h

  Volume Round = (3.14)*(4")^2(2") = 100.5 in^3

Two round pans will hold 2*(100.5 in^3) or 201 in^3 of batter

One rectangular pan holds 234 in^3.

Go with the rectangular pan if you want more cake.
