Hello!

Answer:

$\Large \boxed{\sf CD= 18}$

Step-by-step explanation:

→ We want to calculate CD.

We know that CD = DE.

→ So we have this equation:

$\sf 3x-6 = 2(x+1)$

→ Let's solve this equation to find the value of x to find CD:

◼ Simplify the right side:

$\sf 3x-6 = 2x+2$

◼ Add 6 to both sides:

$\sf 3x-6+6 = 2x+2+6$

◼ Simplify both sides:

$\sf 3x = 2x+8$

◼ Subtract 2x from both sides:

$\sf 3x-2x = 2x+8-2x$

◼ Simplify both sides:

$\sf x = 8$

→ Now, let's calculate CD, let's replace x by 8:

$\sf CD = 3x-6\n\n= 3 * 8 - 6\n\n= 24 - 6\n\n\boxed{\sf= 18}$

Check:

$\sf CD = DE\n\n3x-6 = 2(x+1)\n\n3 * 8 - 6 = 2(8+1)\n\n24 - 6 = 2 * 9\n\n18=18$

So the check is good.

Conclusion:

CD is equal to 18.

If the midpoint between (18, y) and (20, -15) is (19, -5), find the value of y.

Answers

When trying to gather information in order to identify a problem, it is important to find reliable sources.

What is a reliable source?

A reliable source is known to be that source of information that gives a thorough, well-think through theory, argument, etc. and it is one that is found to be true.

So therefore, When trying to gather information in order to identify a problem, it is important to find reliable sources.

B. Find reliable resources

Step-by-step explanation:

A plane is flying due east in still air at 395 km/h. Suddenly, the plane is hit by wind blowing at 55 km/h toward the west. What is the resultant velocity of the plane?

Answers

The resultant velocity relative to the air is still 395 km/hr east.

The resultant velocity relative to the passengers is still zero.

The resultant velocity relative to the ground is (395 east) + (55 west) = 340 km/hr east.

the v towards the air is 395 kn/hr.
v towards passengers is 0.
so the v towards the ground is (395 kn/hr)east + (55km /hr)west = 340
hence solved
welcome :)
