A and B are complementary angles. If m_A = (6x + 29) and m
Liono4ka [1.6K]

Answer:

m∠A=77°

Step-by-step explanation:

Complementary angles are a pair of angles whose measures have a sum of 90°. Since m∠A = 6x+29 and m∠B = x+5, we can write the following equation to solve for x:

6x+29+x+5=90

Solving for x, we get:

6x+29+x+5=90

7x+34=90 (Simplify LHS)

7x+34-34=90-34 (Subtract 34 from both sides of the equation to isolate x)

7x=56 (Simplify)

\frac{7x}{7}=\frac{56}{7} (Divide both sides of the equation by 7 to get rid of x's coefficient)

x=8

Therefore, m∠A=6x+29=6(8)+29=48+29=77°. Hope this helps!

The first step in solving 3.17 t - 2.431 = 5.06 is to divide both sides of the equation by 3.17. TrueFalse
Pavlova-9 [17]

Answer:

False

Step-by-step explanation:

3.17t - 2.431 = 5.06 \\ 3.17t = 5.06 + 2.431 \\ 3.17t = 7.491 \\  \frac{3.17t}{3.17}  =  \frac{7.491}{3.17}  \\ t = 2.363

Please solve and show your work: (-4m^9+2m^7-14m^6)÷2m^3
katrin2010 [14]
The first step for solving this expression is to write the division as a fraction. 
\frac{-4m^{9}+2 m^{7} -14 m^{6}   }{2} × m³
Factor out 2 from the numerator (top) of the fraction.
\frac{2(-2 m^{9} + m^{7}-7 m^{6} )  }{2} × m³
Reduce the fraction with 2.
(-2m^{9} + m^{7} - 7m^{6})m³
Lastly,, distribute m³ through the parenthesis to get your final answer.
-2m^{12} + m^{10} - 7m^{9}
Let me know if you have any further questions.

I need to know Simplify 2a + 8(b + a) is
KonstantinChe [14]
HELLO !

Okay so what you do is<em> eliminate the parenthesis </em>in the equation because it really helps

So you would multiply 8 and b
Also multiple 8 and a

You would get 8b and 8a

Your equation would look like ...

2a + 8b + 8a = ...

<em>Now you add the alike things in the equation </em>

8a and 2a are the alike things.

Now you would have ...

10a + 8b = ?
