Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

I kinda know what to do but at the same time, I'm so lost right now. help
Answer:
THEY messed you upon this one and I don't see if you have to write or not!
More details please and thank you!
Step-by-step explanation:
write an equivalent expression for each of the following by combining like terms
3a+4(5a - 4)=
5b -2(5a -b) + 10a
Answer:
17a - 16
7b
Step-by-step explanation:
Given the following expressions
3a+4(5a - 4)=
Expand
3a + 4(5a)- 4(4)
= 3a + 20a - 16
= 17a - 16
For the expression
5b -2(5a -b) + 10a
Expand
5b - 2(5a)-2(-b) + 10a
5b - 10a + 2b + 10a
= 5b + 2b -10a + 10a
= 7b + 0
= 7b

One method that meteorologists could use to find the height of a layer of clouds about the ground is to shine a bright spotlight directly up onto the cloud layer and measure the angle of elevation from a known distance away. Find the height of the cloud layer in the diagram to the nearest tenth
Answer:
367.6 mStep-by-step explanation:
Use trigonometry
Let the height of the cloud be x, then we have:
tan 35° = x/525x = 525 tan 35°x = 367.6 (rounded)The height of the cloud layer is 367.6 m

3w - 10>-4
Answer:
If your trying to find w then it'll be 2
Step-by-step explanation:
3w - 10 > -4
+10 +10
3w > 6
3 3
w > 2
So I added 10 on both sides and guess positive 10 is bigger than -4, it'll be a positive 6. Then I divide 3 on both sides after I got 6 and thats how I got 2

A roofer props a ladder against a wall so that the top of the ladder reaches a 20 foot roof that needs repair. If the angle of elevation from the bottom of the ladder to the roof is 46 degrees, what is the length of the ladder to the nearest foot?
Answer:
19.33 ft
Step-by-step explanation:
This analogy has to do with Pythagoras theorem.
We're given our angle of elevation to be 46°, and told that the height of the building to be 20 ft. Using Pythagoras theorem, we know that the given height is opposite to the angle of elevation, and thus, the required distance is adjacent to it.
Sin 46° = opp / hyp
Sin 46° = 20 / hyp
hyp = 20 / sin 46
hyp = 20 / 0.719
hyp = 27.82 ft
We've gotten the length of the ladder, our hypotenuse, to be 27.82. It's tied length we'd then use top find the needed length.
Cos 46° = adj / hyp
Cos 46° = adj / 27.82
adj = 27.82 * Cos 46
adj = 27.82 * 0.695
adj = 19.33 ft
Therefore, the required length is approximately equal to 19.33 ft

I need help pls a quick answer would be great. Thanks!
Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3
can someone explain the answer ?
Answer:
x = 9.5
Step-by-step explanation:
Since you are given the adjacent side and need to find the hypotenuse then you need to use cos = adj/hyp so cos (47) = 6.5/x
So x = 6.5/.682, since cos 47 = .6819983601
x = 9.5
