Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.

LA = 5x -5<br> B = 3 + 13<br> B<br> Solve for r and then find the measure of B:
topjm [15]

Answer:

x = 9º

∠B = 40º

Step-by-step explanation:

5x-5º = 3x+13º

<em>[add 5 to both sides]</em>

5x = 3x+18º

<em>[subtract 3x from both sides]</em>

2x = 18º

<em>[divide each side by 2]</em>

x = 9º

/ / / / / / / / / / / / / / / / / / /

3x+13º = 3(9º)+13º=27º+13º = 40º

I really need help with this, my teacher doesn't really teach and I'm stumped again.​
yarga [219]

Answer:

JMK = 54

JKH = 126

HLK = 90

HJL = 27

LHK = 63

JLK = 27

Step-by-step explanation:

Just use 180 for total angles in each triangle. Vertical angles mean the opposite to 126 is 126 and the other two that make up the inner vertices are (360- 126*2)/2 = 54

So, 126, `16, 54 , 54 are the inner angles in the circle. Just go from there.

What are the next two likely terms in each sequence:80.1, 85.3, 90.5, .
AnnyKZ [126]

Answer:

We have 85.3 - 80.1 = 5.2 and 90.5 - 85.3 = 5.2;

So, the next two likely terms are: 90.5 + 5.2 = 95.7 and 95.7 + 5.2 = 100.9;
