Step-by-step explanation:
<u>Use distributive property:</u>
3x+6=4x+4
<u>Eliminate one variable:</u>
Subtract 3x from both sides.
6=x+4
<u>Subtract 4 from both sides:</u>
2=x.
B is correct.
145−5x(0.1)+0.5=14.5
Step 1: Simplify both sides of the equation.
145−5x(0.1)+0.5=14.5
145+−0.5x+0.5=14.5
(−0.5x)+(145+0.5)=14.5(Combine Like Terms)
−0.5x+145.5=14.5
−0.5x+145.5=14.5
Step 2: Subtract 145.5 from both sides.
−0.5x+145.5−145.5=14.5−145.5
−0.5x=−131
Step 3: Divide both sides by -0.5.
−0.5x
−0.5
=
−131
−0.5
x=262
Answer:
x=262
-19.2
12/(-5/8) means 12*(-8/5)
12*8=96
96/5=19.2
don’t forget the negative sign
so
-19.2
Answer:
Step-by-step explanation:
Let X be the solvent present
Then given that the manufacturer of industrial solvent guarantees its customers that each drum of solvent they ship out contains at least 100 lbs of solvent.
X is N(101.3, 3.68)
a) 
Probability = 0.6368
b) 
means Z score = 1.88
X=100+1.88(s) =101.3
s=1.3/1.88=0.6914
Answer:
17.76
Step-by-step explanation:
0.44 x 4 = 1.76
4 x 4 = 16
16+1.76=17.76
