M<MRT 133. What is m<MRN?

liberstina [14]

Answer:

MRN+NRT=MRT

2g-2+4g-9=133

6g-11=133

6g=133+11

6g=144

g=144/6

g=24

MRN=2g-2

=2(24)-2

=48-2

=46°

Hope it helps:-)

What is the vaule of m in this equation 188 = m + 80

Crazy boy [7]

Explanation:

First, switch sides of an equation.

$m+80=188$

Then, you subtract by the 80 from both sides of an equation.

$m+80-80=188-80$

And finally, simplify and subtract the numbers.

$188-80=108$

$\boxed{m=108}$

Hope this helps!

Thank you!

Have a great day!

Answer:

20,9

Step-by-step explanation:

this is how I did=x=1st, y=2nd; x=4y-16 and x+y=29; thus 4y-16+y=29; 5y-16=29; 5y=45; y=45/5=9, once you know y=9, put in equation, 4y-16=×, (4*9)-16=x, 36-16=x, 20=x

Help? Multi-Step Equations - Fractions. Solve the Equation.<br>PLEASE DO IT STEP BY STEP (visual)

GREYUIT [131]

R - 10/3 + 1/2 = -11/6...if u multiply everything by the common denominator 6, it will get rid of the fractions.

(6)r - 6(10/3) + 6(1/2) = 6(-11/6)
6r - 60/3 + 6/2 = - 66/6...simplify
6r - 20 + 3 = - 11
6r - 17 = -11
6r = -11 + 17
6r = 6
r = 6/6
r = 1 <===
