Answer:

$x=26\\$

Step-by-step explanation:

The sum of the interior angles of a triangle add up to $180^{\circ}$ . Therefore, an equiangular triangle will have each of its angles equal to $60^{\circ}}$ . We can then set up the following equation:

$2x+8=60, \\2x=52, \\x=\fbox{$26$}$ .

The little Mexican restaurant sells only two kinds of beef burritos mucho beef sandwich Lucho beef last week the restaurant orde

Finger [1]

Answer:

Cost of a single Mucho beef burrito: $\$5.5$

Cost of a double Mucho beef burrito: $\$6.5$

Step-by-step explanation:

<h3> The exercise is: "The Little Mexican restaurant sells only two kinds of beef burritos: Mucho beef and Mucho Mucho beef. Last week in the restaurant sold 16 orders of the single Mucho variety and 22 orders of the double Mucho. If the restaurant sold $231 Worth of beef burritos last week and the single neutral kind cost $1 Less than the double Mucho, how much did each type of burrito cost?"</h3>

Let be "x" the the cost in dollars of a single Mucho beef burrito and "y" the cost in dollars of a double Mucho burrito.

Set a system of equations:

$\left \{ {{16x+22y=231} \atop {x=y-1}} \right.$

To solve this system you can apply the Substitution Method:

1. Substitute the second equation into the first equation and solve for "y":

$16(y-1)+22y=231\\\\16y-16+22y=231\\\\38y=231+16\\\\y=\frac{247}{38}\\\\y=6.5$

2. Substitute the value of "y" into the second equation and evaluate in order to find the value of "x":

$x=6.5-1\\\\x=5.5$

U=(1,2,3,4,5,6,7,8),a=(1,3,5,7), b=(4,5,6) is it true statement

kvv77 [185]

<u>Answer:</u>

U=(1,2,3,4,5,6,7,8), a=(1,3,5,7), b=(4,5,6) is false statement

<u>Solution:</u>

Given, two sets are a = (1, 3, 5, 7) and b = (4, 5, 6).

And their union set is U = (1, 2, 3, 4, 5, 6, 7, 8)

We have to find that whether above sets are true or not.

We know that, union of two sets will have the all elements in the two sets except the repeated elements.

Now, according to our knowledge.

Union of a and b = (1, 3, 5, 7, 4, 6)

Now compare the given union set with our set.

After comparison we can say that, both are not equal which means that given union set is false set.

Hence, given statement is false.

What is the value of y?<br><br><br><br> Enter your answer in the box.<br><br> y =

Olenka [21]

Answer:

$y=40\°$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles triangle

so

$AB=AC$

$5x=40\°$

$x=8\°$

The sum of the internal angles of a triangle is equal to $180\°$

so

Find the value of y

$(2y+20)\°+2(40\°)=180\°$

$2y=180\°-20\°-80\°$

$2y=80\°$

$y=40\°$
