  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2x - 9y = 11

<em>x</em> = 7

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                                                                                                  2(7) - 9y = 11
  2. Multiply:                                                                                                             14 - 9y = 11
  3. [Subtraction Property of Equality] Subtract 14 on both sides:                       -9y = -3
  4. [Division Property of Equality] Divide -9 on both sides:                                 y = 1/3

Simplify 3/4(1/2×-12)+4/5​
Wittaler [7]

Answer: \frac{3}{8}x-\frac{41}{5} or  \frac{3}{8}x-8\ \frac{1}{5}

Step-by-step explanation:

Given the following expression:

\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}

You can follow these steps in order to simplify it:

1.  You need to apply Distributive property:

=\frac{3}{8}x-9+\frac{4}{5}

2. And now you must add the like terms. Then:

=\frac{3}{8}x-\frac{41}{5}

Therefore you get the following answer:

\frac{3}{8}x-\frac{41}{5} or  \frac{3}{8}x-8\ \frac{1}{5}

One base of a trapezoid is five times as long as the other. The height is the average of the two bases. The area is 441 square u
Gelneren [198K]

Answer:

The length of the longer base he 35 units

Step-by-step explanation:

Here, we want to find the length of the longer base of the trapezoid

Mathematically, we can find the area using the formula;

1/2( a + b) h

where a is the shorter base

b is the longer base

h is the height

Let the shorter base be x

The other base is 5 times this length and that makes 5 * x = 5x

Height is the average of both bases;

(x + 5x)/2 = 6x/2 = 3x

Substituting these in the formula, we have ;

1/2(x + 5x)3x = 441

3x(6x) = 882

18x^2 = 882

x^2 = 882/18

x^2 = 49

x^2 = 7^2

x = 7

But the longer base is 5x and that will be 5 * 7 = 35 units
