Answer:
<h2>A)
x = 6, m∠LMN = 138°</h2><h2>
</h2>
Step-by-step explanation:
∠LMO = ∠NMO
15x - 21 = x + 63
15x - x = 63 + 21
14x = 84
x = 84/14
x = 6
∠LMN = ∠LMO + ∠NMO
∠LMN = 15x - 21 + x + 63
∠LMN = 15(6) - 21 + 6 + 63
∠LMN = 138°

I solved this with graphing and got d trust me
pls mark brainliest
Step-by-step explanation:
you mixed an 8% and a 12% solution together.
so, you get (8%×mass1 + 12%×mass2)/((mass1 + mass2)/2) as resulting % of the combined solution.
since the result is 10%, which is precisely the arithmetic middle
(8 + 12)/2
we see that mass1 = mass2.
in other words : the same quantity (mass) of the 8% solution and the 12% solution was mixed together.
so, 760g = 2×mass
=>
mass = 380g
380g of the 8% solution and 380g of the 12% solution were mixed together.
