Step-by-step explanation:

First, you do what is inside the parantheses, so 11 - 5 is 6, then you multiply 1 x 2 = 2, and 3 x 6 is 18. Lastly, you add it all up and get the sum of 27. Hope this helps!

Answer:27

Step-by-step explanation:

3x 11 is 33 and 3 x 5 is 15 then you would do 1 x 2 which is 2 then you would add 2 to 33 which is 35 then subtract 15 which is 20 then add 7 to get 27

$17 \sqrt{2}$

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.

so, x = 17 (isosceles triangle)

then use pythagoreas theorem:

$y = \sqrt{x {}^{2} + 17 {}^{2} }$

and x = 17, so simplify and

$y = \sqrt{17 {}^{2} + 17 {}^{2} }$

$y = 17 \sqrt{2}$

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one sam

Serga [27]

Answer:

Price of advance ticket: 15$

Price of same-day ticket: $40

Step-by-step explanation:

Let $y$ be the price of one advance ticket and $x$ the cost of one same day ticket.

We know that the combined cost of one advance ticket and one same-day ticket is $55, so

$y+x=55$ equation (1)

We also know that 20 advance tickets and 35 same-day tickets cost $1700, so

$20y+35x=1700$ equation (2)

Now, let's solve our system of equations step-by-step:

step 1. Solve for $x$ in equation (1)

$y+x=55$

$x=55-y$ equation (3)

step 2. Replace equation (3) in equation (2)

$20y+35x=1700$

$20y+35(55-y)=1700$

$20y+1925-35y=1700$

$-15y=-225$

$y=\frac{-255}{-15}$

$y=15$ equation (4)

step 3. Replace equation (4) in equation (3)

$x=55-y$

$x=55-15$

$x=40$

We can conclude that the price of one advance ticket is $15 and the price of one same-day ticket is $40.

If each acute angle of a parallelogram measures 59 degrees, then what is the masure of each obtuse angle?

xenn [34]

A parallelogram has to have a total of 360 degrees in angles, so we take 59 x 2 to get 118, we then subtract 118 from 360, 360 - 118 = 242, we then divide by two because a parallelogram has 2 obtuse angles, giving us an answer of 121 degrees. Hope this helps
