When height turns to 3 times height or 3h

we can replace h with 3h and see what happens

A=1/2b(3h)
A=3/2bh
A=3(1/2bh)
well, the area is trippled

Bogdan [553]

Answer:

14.4acres

Step-by-step explanation:

The total acres is 48 acres, which is 100%

when you add percentage of others, wheat and cotton you get 70%.

which leaves you with 30%

therefore, 30% of the land is for corn..

which is 14.4 acres.

0.30 x 48acres= 14.4 acres

hope this helped:)

Question 7

(37,065 - 26, 102)/(37, 065) = P/100

(10, 963)/(37, 065) = P/100

37, 065P = (10, 963)(100)

37,065P = 109, 630

P = 109, 630 ÷ 37, 065

P = 2.9577768785

P = 295.78%

Do likewise for the rest of the questions.

To change from decimal to percent, move the decimal point two places to the right and then add the percent symbol (%).

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

8x - (2x - 13) = 42

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

  1. [Distributive Property] Distribute negative:                                                     8x - 2x + 13 = 42
  2. [Subtraction] Combine like terms:                                                                    6x + 13 = 42
  3. [Subtraction Property of Equality] Subtract 13 on both sides:                        6x = 29
  4. [Division Property of Equality] Divide 6 on both sides:                                 x = 29/6

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                                                                                                  8(29/6) - [2(29/6) - 13] = 42
  2. Multiply:                                                                                                             116/3 - [29/3 - 13] = 42
  3. [Brackets] Subtract:                                                                                           116/3 - -10/3 = 42
  4. Subtract:                                                                                                            42 = 42

Here we see 42 does indeed equal 42.

∴ x = 29/6 is the solution.
