Answer:

X = 7

AB = 14

BC = 14

CA = 14

Step-by-step explanation:

This is an equilateral triangle so you can set the lengths equal to each other in order to find X.

2x=x+7

 -x    -x

x=7

you can do this with any combination of the lengths and you will always get 7

Now you plug in 7 for x

Original: 2x

Plug in 7: 2*7

You get 14

Since this is after all, an equilateral triangle all lengths are equal so all lengths are 14.

Hello!

<em><u>Answer:</u></em>

<em><u>4 5/12</u></em>

<em><u>*The answer must have a whole number and a fraction.*</u></em>

Step-by-step explanation:

Lesson: Adding Fractions

First, you add by the whole number.

1+2=3

Then you combine by the fraction or number.

\frac{3}{4}+\frac{2}{3}=\frac{17}{12}

3+\frac{17}{12}

Next, you convert improper fraction into the mixed numbers.

\frac{17}{12}=1\frac{5}{12}

3+1\frac{5}{12}

And finally, add by the numbers.

3+1=4

Final answer: → 4\frac{5}{12}

Hope this helps!

Thanks!

Have a great day!

Answer:

d= 8.6 ft

Step-by-step explanation:

In similar triangles, the corresponding sides are in proportion.

\boxed{\dfrac{AW}{MZ}=\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}}

To find the value of x,

\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}\\\\\\\dfrac{6}{7}=\dfrac{d}{10}\\\\\\\dfrac{6}{7}*10=d

d = 8.6 ft

A restaurant offers a​ $12 dinner special that has 77 choices for an​ appetizer, 1010 choices for an​ entrée, and 44 choices for
krok68 [10]
<span>280 I'm assuming that this question is badly formatted and that the actual number of appetizers is 7, the number of entres is 10, and that there's 4 choices of desserts. So let's take each course by itself. You can choose 1 of 7 appetizers. So we have n = 7 After that, you chose an entre, so the number of possible meals to this point is n = 7 * 10 = 70 Finally, you finish off with a dessert, so the number of meals is: n = 70 * 4 = 280 Therefore the number of possible meals you can have is 280. Note: If the values of 77, 1010 and 44 aren't errors, but are actually correct, then the number of meals is n = 77 * 1010 * 44 = 3421880 But I believe that it's highly unlikely that the numbers in this problem are correct. Just imagine the amount of time it would take for someone to read a menu with over a thousand entres in it. And working in that kitchen would be an absolute nightmare.</span>
