Subtract 4.58 on both sides, which is 2.5 - 4.58 = -2.08
THEREFORE; y = -2.08

A countertop is 16ft long &amp; 3ft wide what is the area in square meters
astra-53 [7]

ANSWER

Find out the area of the  countertop in square meters .

To proof

As given

A countertop is 16ft long & 3ft wide.

A countertop is in the shape of the rectangle.

FORMULA

Area of a rectangle = length × breadth

long = 16ft

wide = 3ft

put the value

we get

Area of a countertop = 16 ×3

                                   = 48 feet²

1 meter = 3.281 feet

1feet = \frac{1}{3.281} meter

convert Area of a countertop in  square meters

= \frac{48\times1\times1}{3.281\times3.281}

=  4.461 m² ( approx )

Hence proved

A Bill in the U.S House of Representatives passed because at least 2/3 of the members present voted in favor of it. If the bill
otez555 [7]

Answer:

Members of the House of Representatives present for the vote were atleast 426 .

Step-by-step explanation:

As given

A Bill in the U.S House of Representatives passed because at least \frac{2}{3} of the members present voted in favor of it.

If the bill received 284 votes .

Let us assume that the total members of the House of Representatives were present for the vote be x .

Than the equations becomes

\frac{2}{3}\times Total\ number\ of\ Representatives\ present\ for\ vote \geq 284

\frac{2}{3}\times x \geq 284

2x \geq 284\times 3

2x \geq 852

x\geq \frac{852}{2}

x\geq 426

Therefore members of the House of Representatives present for the vote were atleast 426 .

Using your answer from part (b) and inequality symbols, write one statement that shows the relationship among all of the numbers
Natali5045456 [20]

Answer:

(b) Least to greatest numbers are -1.0, -\frac{1}{4} , 0, 0.5, 1.5

(c) -1.0 <  -\frac{1}{4}  < 0 < 0.5 < 1.5

OR

1.5 > 0.5 > 0 >  -\frac{1}{4}  > -1.0

Step-by-step explanation:

P.S - The exact question is -

Given - Kendra collected data for her science project. She surveyed

             people asking them how many hours they sleep during a

             typical night.

             The chart below shows how each person’s response compares

              to 8 hours (which is the answer she  expected most people to say).

Name                Number of Hours                       Compared to Hours

                         (usually slept each night)

Frankie                        8.5                                                    0.5

Mr. Fields                      7                                                      −1.0

Karla                             9.5                                                     1.5

Louis                             8                                                         0

Tiffany                            7\frac{3}{4}                                                       -\frac{1}{4}

To find - (a) Plot and label each of the numbers in the right-most column

                   of the table above on the number line below.

               (b) List the numbers from least to greatest.

                (c) Using your answer from part (b) and inequality symbols,

                     write one statement that shows the relationship  among all

                     of the numbers.

Proof -

(a)

We can see that the numbers in the right-most column are  0.5, -1.0, 1.5, 0, -\frac{1}{4}

We can write -\frac{1}{4} = -0.25

Now,

We have to label them in the number line

The number line is as follows :

(b)

Least to greatest numbers are -1.0, -\frac{1}{4} , 0, 0.5, 1.5

(c)

By using inequality symbol, we get

-1.0 <  -\frac{1}{4}  < 0 < 0.5 < 1.5

OR

1.5 > 0.5 > 0 >  -\frac{1}{4}  > -1.0

When (8x − 4) = 2x is solved, the result is:
notsponge [240]

Answer:

x = 1

General Formulas and Concepts:

<u>Pre-Algebra</u>

Distributive Property

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

1/2(8x - 4) = 2x

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

  1. [Distributive Property] Distribute 1/2:                                                              4x - 2 = 2x
  2. [Subtraction Property of Equality] Subtract 2x on both sides:                      2x - 2 = 0
  3. [Addition Property of Equality] Add 2 on both sides:                                    2x = 2
  4. [Division Property of Equality] Divide 2 on both sides:                                  x = 1
