4(x-1) = -1(6x-36)
=> 4x-4 = -6x+36
=> 4x-4+4 = -6x +36+4
=> 4x+6x = -6x+6x+40
=> 10x = 40
=> (10x)/10 = 40/10
=> x = 4.
The measures of three of the interior angles of a quadrilateral are 60°, 110°, and 90°. What is the measure of the fourth angle of this quadrilateral?
Answer:
100°
Step-by-step explanation:
all four angles added together total 360°
x = 360° - 60° - 110° - 90°
x = 100°

Answer: 22
Step-by-step explanation:
Here, we need to know the concept of changing signs. Under any circumstances, if there is a "-" sign outside of parenthesis, the signs inside need to be the opposite. If you are still not very clear, I can provide some examples below:
1-(+1) ⇒ there is a "-" sign, so we need to convert the sign inside "+" to "-" ⇒ 1-1 ⇒ 02-(-1) ⇒ there is a "-" sign, so we need to convert the sign inside "-" to "+" ⇒ 2+1 ⇒ 3-------------------------------------------------------
Given
13 - (-9)
⇒There is a "-" sign outside
⇒We need to convert the sign inside "-" to "+"
⇒13+9
⇒22

Mark this and retum
Answer: are perpendicular
Step-by-step explanation:
Two lines intersecting at a right angle are said to be perpendicular. When the lines cross each other, we say the lines have intersected.
The point of intersection of the lines is the pointe where they cross one another. In case the lines never interesct, such lines are refered to as the parallel lines.
Mark runs to catch a ball. Explain how the structure of muscle tissue helps him perform this function
Answer:
Muscles give structure and power for any kind of movement, so the tissue needs to be flexible and tightly packed for movement. The tight bands of tissue shown in the picture allows this movement to occur.
Step-by-step explanation:
By running your muscles can get stronger in power so it gives you a better chance to catch the ball with your speed and strength.
Answer:
Muscles give structure and power for any kind of movement, so the tissue needs to be flexible and tightly packed for movement. The tight bands of tissue shown in the picture allows this movement to occur.

Which is a greater angle of rotation? 720° or 6π radians? Explain how you know.
Answer: the angle would be much greater because the angle calculated up to over 12 radians
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 6 \pi \ radians}}[/tex]
Step-by-step explanation:
It's hard to compare degrees and radians, so we should convert, then compare.
To convert radians to degrees, we multiply by 180 over pi. This way, the pi will cancel out when dividing.
[tex]radian * \frac {180}{\pi}[/tex]
[tex]6 \pi * \frac {180}{\pi}[/tex]
[tex]\frac {1080 \pi}{\pi} \\[/tex]
[tex]1080[/tex]
6π radians is equal to 1080 degrees, which is much larger than 720 degrees, so it is the greater angle of rotation.

You have been asked to analyze the popcorn recipes of three different local theatres in order to figure out which theatre has the best popcorn. In this case, the "best" popcorn is the most buttery! In your quest to find the best, you meet with each theatre manager individually and ask for the ratio of oil to popcorn kernels that they use in their recipes. Here are their responses.
The manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.

Theatre A uses 2 cups of salt for
every 10 cups of oil.
Theatre B uses 1/8 cup salt for every cup of oil.
Theatre C uses 1 cup of salt for every 6 cups of oil.
For Theatre C, the ratio of oil to popcorn kernels can be described by the equation _____.
O = 4 × P
O = 1/4 × P
O = 3/16 × P

Answer:
Equation B, 10 + 5.50n = y.
Step-by-step explanation:
N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.
Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.
If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)
Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.
You need to add 10 to 5.50, in order to get the total amount, or y.
The final equation is going to be 5.50n + 10 = y, or choice B.
