Solve for the value of p. (6p-2) न (3p-7)|

Westkost [7]

Answer:

The sum of angles on a straight line is 180 degrees.

Therefore,

$(6p-2)+(3p-7)=180$

$6p-2+3p-7=180$

$9p-9=180$

$9p=189$

$p=21$

A coat that usually cost $123 is marked 1/3 off. what is the sale price of the coat

Snowcat [4.5K]

Well if it is marked 1/3 off, then you're actually paying 2/3 of it. 2/3 of 123. " of " means multiply 2/3 * 123 = 246/3 = 82 So it now costs $ 82

Maya says that value of the 6 in 0.006 is 1/10 of the value of the 6 in 0.6 . Is she correct? Explain

Nikolay [14]

Answer:

Maya is NOT correct as

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$

Step-by-step explanation:

The value of 6 in 0.006 = $\frac{1}{1000}$

Also, the value of 6 in 0.6 = $\frac{1}{10}$

But, $\frac{1}{1000}$ is not 1/10 of the value $\frac{1}{10}$

as 1/10 of the value $\frac{1}{10}$ = $\frac{1}{100}$

Hence,Maya is NOT correct.

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$

X=4
After squaring both sides, you get
4(x+5)=x^2-20x+100
Multiply
4x+20=x^2-20x+100
Collect like terms
4x+20-x^2+20x-100=0
Reorder
24x-80-x^2=0
Change signs & Write as difference. You end up with
x^2-4x-20x+80=0
Factor
x-4=0 , x-20=0
4=4 , 0=20
x=4
