80\frac{1}{2}:\frac{2}{5}=\frac{80\cdot2+1}{2}:\frac{2}{5}=\frac{161}{2}\cdot\frac{5}{2}=\frac{805}{4}=\frac{804+1}{4}=\frac{804}{4}+\frac{1}{4}=\boxed{201\frac{1}{4}}

80.5 ÷ 0.4 = 201.25
Or 
80 ½ ÷ 2/5 = 201 ¼

Lines N and Pare parallel. Angle M measures 126 degrees. Find the measure of angle Q.
DochEvi [55]

Answer:

Q= 126°

Step-by-step explanation:

Using the picture given, because these are parallel lines broken by a transversal, we can say the following

M=A=Q=F

B=C=D=G

Since, for example, M and C are the same line, we can say that M+C=180 and so on.

M=Q

Q= 126°

Answer:

2x + 3y = 6 ---(1)\\y = \frac{x}{6}  - 3 ----(2)\\\\substitute \ y \ in \ (1)\\2x + 3(\frac{x}{6}  - 3) = 6\\\\2x + \frac{x}{2}  - 9 = 6\\\\\frac{5x}{2}  = 6+9\\\\\frac{5x}{2} = 15\\5x = 30 \\x = 6\\substitute \ x \ in \ (2)\\\\y = \frac{6}{6} -3 = 1 - 3= -2

x = 6, y = -2

Anyone know the answer?
yan [13]

Answer:

0.

Step-by-step explanation:

The angle whose sine is 5/12 = 22.62 degrees and in Quadrant II it is

180 - 22.62 degrees

The angle whose tan is (5/12)  = 22.62.

So we can write  α as 180 - α  and β as α.

sin (α+β) = sin ( 180 - α = α) = sin 180

= 0.

The price of a video game was reduced from $60 to $45. by what percentage was the price of the video game reduced what is the an
lara31 [8.8K]

Answer:

Hey.

By what percentage was the price of the video games reduced ?

By 25%.

Step-by-step explanation:

$60 is the 100% price.

Now we have to find what percentage belongs to the reduced price, $45.

45×100/60 = 75.

75% is the percentage of the reduced price.

We can find the difference between them by doing a substraction.

100%-75% = 25%.

Hope I helped you !
