D. \frac{21 \: b}{10}  - 48 ✅

Step-by-step explanation:

- 6( \frac{1}{4}  b+ 10) + 4( \frac{9}{10}b  + 3) \\  =  \frac{ - 6 \: b}{4}  - 60 +  \frac{36 \: b}{10}  + 12 \\  =  \frac{ - 3 \: b}{2}  +  \frac{18 \: b}{5}  - 60 + 12 \\  =   \frac{ - 3 \: b \times 5}{2 \times 5}  +  \frac{18 \: b \times 2}{5 \times 2}  - 48 \\  =  \frac{ - 15 \: b + 36 \: b}{10}  - 48 \\  =  \frac{21 \: b}{10}  - 48

I WILL GIVES BRAINLIEST!!!!
andrew-mc [135]

Answer:

3 1/3 cups

Step-by-step explanation:

one and one half dozen = 1.5 * 12 = 18 cookies


18 cookies    90 cookies

---------------- = -------------

2/3 cup          x cups

using cross products

18 * x = 2/3 * 90

18 x = 60

divide each side by 18

x = 60/18    

divide top and bottom by 6

x = 10/3

change the improper fraction to a mixed number

3 goes into 10 3 times with 1 left over

x = 3 1/3 cups

What is the vertex of the parabola with the equation y=1/5x^2 + 2x - 8
bixtya [17]

Answer:

(-5,-13)

Step-by-step explanation:

Find the vertex of the parabola y=1/5x^2+2x−8.  

In this equation a=15  and b = 2.  

x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5

Substitute −5 into the equation y=1/5x^2+2x−8

y=1/5(−5)^2+2(−5)−8

y=5−10−8

y=−13

The vertex is (−5 , −13)

What is the answer to this equation t+t+t=12
OLEGan [10]

Answer:

t = 4

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define equation</u>

t + t + t = 12

<u>Step 2: Solve for </u><em><u>t</u></em>

  1. Combine like terms (t):                    3t = 12
  2. Divide 3 on both sides:                   t = 4

<u>Step 3: Check</u>

<em>Plug in t into the original equation to verify it's a solution.</em>

  1. Substitute in <em>t</em>:                    4 + 4 + 4 = 12
  2. Add:                                    8 + 4 = 12
  3. Add:                                    12 = 12

Here we see that 12 does indeed equal 12.

∴ t = 4 is a solution of the equation.
