6. When solving for the value of x in the equation, Martha wrote the following lines on the board.

Step 1 4(x - 1) + 3 = 18
Step 2 4(x - 1) = 15
Step 3 4x - 1 = 15
Step 4 4x = 16
Step 5 x = 4

Which property was used incorrectly when going from Step 2 to Step 3?

a. Addition Property of Equality
b. Distributive Property of Equality
c. Substitution Property of Equality
d. Transitive Property of Equality

We have to find the perimeter of the park and then add 50m to that

Perimeter = 2(l+b)

                 = 2(275+200)

                 = 2* 475

                 = 950m

Therefore: Total distance covered = 950+50 = 1000 m(1km)

Answer:

This quadrilateral is a SQUARE.

When we plot these points, we realize that they are equal distance apart.

So, when a quadrilateral has sides that are equal distance apart, that quadrilateral is a square.

Answer:

$1.67

Step-by-step explanation:

Given it's $1.12 for 12 eggs, we divide 1.12 by 12 to see how much it cost for 1 egg

1.12/12 = 0.093

so 0.093 cents for 1 egg

0.093x18 eggs = 1.674 = $1.67

Hope this helps, have a nice day :)

Answer:

M=-9/8

Step-by-step explanation:

-3/8-3/4=-3/8-6/8=-9/8

Answer:

m = -9/8

Step-by-step explanation:

First, let's get m by itself by subtracting 3/4 from both sides:

m = -3/8 - 3/4

The least common denonimator between our two fractions is 8, so we can turn 3/4 into the equivalent fraction 6/8 to subtract our two fractions:

m = -3/8 - 6/8 = -9/8

The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

Let the value is C.

The Pythagoras' theorem,

C² = (11)² + (12)²

C² = 121 + 144

C² = 265

C = 5.1 feet.

Therefore, the value is 5.1 feet.

Answer:

1. x=5/4

2. x=-4

3. x= 9/10

Step-by-step explanation:

Let's solve your equation step-by-step.

−x+3=3x−2

Step 1: Subtract 3x from both sides.

−x+3−3x=3x−2−3x

−4x+3=−2

Step 2: Subtract 3 from both sides.

−4x+3−3=−2−3

−4x=−5

Step 3: Divide both sides by -4.

−4x/−4 = −5/ −4

x= 5/4

Answer:

x= 5/4 (5 over 4)

Let's solve your equation step-by-step.

1.5x−3=2.25x

Step 1: Subtract 2.25x from both sides.

1.5x−3−2.25x=2.25x−2.25x

−0.75x−3=0

Step 2: Add 3 to both sides.

−0.75x−3+3=0+3

−0.75x=3

Step 3: Divide both sides by -0.75.

−0.75x/−0.75=3/−0.75

x=−4

Answer:

x=−4

Let's solve your equation step-by-step.

−1/3x+2=3x−1

Step 1: Subtract 3x from both sides.

−1/3x+2−3x=3x−1−3x

−10/3x+2=−1

Step 2: Subtract 2 from both sides.

−10/3x+2−2=−1−2

−10/3x=−3

Step 3: Multiply both sides by 3/(-10).

(3/−10)*(−10/3x)=(3/−10)*(−3)

Answer:A=2,4,6,8

One way of writing this in set builder notation could be:

A={x|2≤x≤8|x2∈N}

Which can be interpreted as:

The set A is the set of any  x  such that  2≤x≤8  such that half of  x  is a natural number ( N ).

There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e.  ∈ , | , N ), it becomes much easier to “read as a sentence”.

Here are a few more ways of writing the set  A=2,4,6,8  in set builder notation:

A={x|2≤x≤8|x∈2⋅N}

A={x|(x−2)(x−4)(x−6)(x−8)=0}

A={x|x=2p|p∈{1,2,3,4}}

A={x∈N|mod(x,2)=0|x≤8}

Answer:

56/19

Step-by-step explanation:

I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...

2X + 5(1.5X) = 8

2X + 7.5X = 8

9.5X = 8

19X = 16

X = 16/19

While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...

3X = 2Y

3(16/19) = 2Y

48/19 = 2Y

24/19 = Y

With the value of X and the value of Y, we can answer the question that's asked:

2X + Y = ?

2(16/19) + 24/19 =

32/19 + 24/19 =

56/19

Final Answer: 56/19

Answer:

[tex]x = - 1[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

[tex]3x + 2y = - 7[/tex]

[tex]2x - 5y = 8[/tex]

Apply elimination method. Let multiply the bottom equation by -3/2.

[tex]2 \times - \frac{3}{2} x = - 3[/tex]

[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]

[tex]8 \times - \frac{3}{2} = - 12[/tex]

Substitute new equation and add it to the top equation

[tex]3x + 2y = - 7[/tex]

[tex] - 3x + 7.5y = - 12[/tex]

[tex]9.5y = - 19[/tex]

[tex]y = - 2[/tex]

Now plug -2 for y into any equation and solve for x.

[tex]3x + 2( - 2) = - 7[/tex]

[tex]3x - 4 = - 7[/tex]

[tex]3x = - 3[/tex]

[tex]x = - 1[/tex]
