Answer:

C. 3x + 8

Step-by-step explanation:

A. can be factored; Factor 5 from all terms:

(15x - 10)/5 = 3x - 2

B. can be factored; Factor 4 from all terms:

(4x + 8)/4 = x + 2

D. can be factored; Factor 2 from all terms:

(2x - 2)/2 = x - 1

Answer:

$y = 30$

<u>Skills needed: Angle Geometry</u>

Step-by-step explanation:

1) First, let's see what we should know prior to solving.

---> We have to find the value of $y$ , and looking at that diagram, we have to create an equation.

---> The angle measure of a straight line is 180 degrees, otherwise known as a straight angle (a straight angle is 180 degrees).

---> When you add $3y+3y$ , you can set that sum equal to 180. This is because the two angles marked $3y$ added together make a straight line, which is a straight angle.

(Note: In geometry, ONE OF THE THINGS WE CAN ASSUME is that there is a straight line there.)

-------------------------------------------------------------------------------------------------------------

2) Now, the equation would be:

$3y+3y=180$

$6y=180$ --> Combining $3y$ and $3y$ (3+3 = 6)

$y = 180\div6$ --> Dividing by 6 on both sides, to get $y$ by itself.

$y=30$ ---> $180 \div 6$ is 30, so $y$ is equal to 30.

$y=30$

You are building a house and are making a drawing of the kitchen. the sink is 3 feet away from the dishwasher, and the sink is 8

Natasha_Volkova [10]

Consider the triangle with vertices S (sink), D (dishwasher) and F (fridge). From the conditions data SD=3, SF=8 and ∠S=48°.

Use the cosine theorem to find unknown distance:

$FD^2=SD^2+SF^2-2SD\cdot SF\cdot \cos S$ ,

$FD^2=3^2+8^2-2\cdot 3\cdot 8\cdot \cos 48^{\circ},\\ FD^2=9+64-48\cdot 0.67,\\ FD^2=40.84, \\ FD=\sqrt{40.84}, \\ FD=6.39$ feet.

Then the distance between dishwasher and fridge is 6.39 feet.

Are these dimensions reasonable is up to kitchen owner))
