Given:

The sides of a triangles in the options.

To find:

Which of the following cannot be the lengths of the sides of a triangle?

Solution:

In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.

For option A,

[tex]6+8=14>12[/tex]

For option B,

[tex]4+4=8>12[/tex]

For option C,

[tex]6+6=12[/tex]

Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.

For option D,

[tex]6+8=14>10[/tex]

Therefore, the correct option is C.

Answer:

You just subtract 126 degrees from 180 degrees = 34 degrees for all angles

The measures of the angles ∠2,∠4,∠6, and ∠8 are 54°, 54°, 54°, and  54° respectively or all the angles are the same.

It is given that in the figure the line p and line q are parallel to each other.

It is required to find the measures of all angles.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

We have two lines p and q which are parallel to each other, line t is crossing both lines as shown in the figure.

∠1 = 126° and ∠3 = 126°

For the angles ∠2 and ∠4:

∠2 = 180° - 126° ⇒ 54°

From the definition of the vertically opposite angle:

∠2 =∠4 = 54°

∠5 = 126° and ∠7 = 126°

∠8  = 180 - 126° = 54°

From the definition of the vertically opposite angle:

∠8 = ∠6 = 54°

Thus, the measures of the angles ∠2,∠4,∠6, and ∠8 are 54°, 54°, 54°, and  54° respectively or all the angles are the same.

Answer:

After the sixth week, she would have more than enough money to buy the racket.

Step-by-step explanation:

First Week

Sarah = 40 + 10 = 50

Owner = 120 - 5 = 115

Second Week

Sarah = 50 + 10 = 60

Owner = 115 - 5 = 110

Third Week

Sarah = 60 + 10 = 70

Owner = 110 - 5 = 105

Fourth Week

Sarah = 70 + 10 = 80

Owner = 105- 5 = 100

Fifth Week

Sarah = 80 + 10 = 90

Owner = 100 - 5 = 95

Sixth Week

Sarah = 90 + 10 = 100

Owner = 95 - 5 = 90

After the sixth week, she would have more than enough money to buy the racket.

How many weeks until Sara has enough money to buy the racket?

40 + 10x = 120 - 5x

10x + 5x = 120 - 40

Answer:

G-$3000, L- $1200, M- $1800

Step-by-step explanation:

Georgia= 5/10 * 6000= $3000

Leanee= 2/10 * 6000= $1200

Maya= 3/10 * 6000= $1800

If a prize of $6000 was divided among Georgia, Leanne and Maya to the ratio of 5:2:3 Georgia received $3000, Leanne received $1200, and Maya received $1800.

To find out how much each girl received, we can divide the prize of $6000 according to the given ratio of 5:2:3.

First, let's calculate the total parts in the ratio:

Total parts = 5 + 2 + 3 = 10

Now, we can determine the share of each girl by dividing the total prize by the total parts and multiplying it by the respective ratio:

Georgia's share = (5/10) * $6000 = $3000

Leanne's share = (2/10) * $6000 = $1200

Maya's share = (3/10) * $6000 = $1800

Therefore, Georgia received $3000, Leanne received $1200, and Maya received $1800.

Answer:

1. Choose: 3

2. Choose: 144

3. Choose: 18

Step-by-step explanation:

The first thing you do is multiply 48 * 3/8= 18.  Then multiply 48 * 1/8= 6.  Then divide both answers to get 3, so 48 * 1/8 * 3.

Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).

Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

Answer:

A -1

Step-by-step explanation:

The coefficient is the number in front of a variable. since there isn't a number we can conclude that the y is only there once. There is 1 (one) y. Since it is subtracting in front of the coefficient, we can determine it is taking one away, or -1. So 6-y+3 is 6-1y+3.

Answer:

m=9

Step-by-step explanation:

3m-6-2m=3

Combine like terms

3m-2m=1m

1m-6=3

Add 6 to both sides

1m=9

Divide both sides by 1

m=9

Hi there! Your answer is m = 9

Please see the explanation for a clear understanding to the problem.

Any questions about the answer/explanation, feel free to ask in comments! :)

Step-by-step explanation:

Goal

Given

[tex]\Large{3m-6-2m=3}[/tex]

Step 1

Like terms are the terms have same variables. For example, 2m and 3m. 2m and 3m both are like terms because they both have same variable which is m-term.

But 2m and 3a are not like terms because 2m has m-term as a variable but 3a has a-term as a variable. Both are terms but not like terms.

From the equation:

[tex]3m-2m=3+6[/tex]

Since we combine like terms, we can't combine a constant with a variable so we move to the side where they are alike.

Evaulate 3m-2m = m and 3+6 = 9

[tex]m = 9[/tex]

There aren't really much steps solving this. The next step is going to be how to check an answer. It's useful when you are not certain or sure about the answer that you get. If you are not certain on the answer, this step is highly advised for a beginner.

Optional Steps - Answer Check

Step 2

The step is optional as said. From the equation:

[tex]3m-6-2m=3[/tex]

We can do this two ways which are when we simplify the equation then substitute in the value of m or we substitute m-value first then simplify/evaluate.

I will be demonstrating these two steps to you.

Step 2.1

[tex]3m-6-2m=3\\3m-2m=3+6\\m=9\\9=9[/tex]

Step 2.2

[tex]3m-6-2m=3[/tex]

Substitute m = 9 in the equation.

[tex]3(9)-6-2(9)=3\\27-6-18=3\\9-6=3\\3=3[/tex]

Notice that no matter which method you use, you'd still get the same answer. Since the equation is true for m = 9. Therefore, the solution is m = 9.
