Answer:

Please find the answer below

Step-by-step explanation:

2a-b+c= -5 ----(A)

a-b+c= -5 ------(B)

2a+b =5 -------(C)

from equation A subtracting 2a from both sides we get

-b+c = -5-2a

Substituting this value in B

a-5-2a=-5

a-2a-5+5=0

-a=0

a=0

Putting this value in C

2(0)+b=5

b=5

Putting these values in B

0-5+c=-5

c=0

We do not have any option with these solutions . Hence, it seems that there is something missing from the equation.

If p-1/p = 4 Find (p+1/p)²

DiKsa [7]

Answer:

Step-by-step explanation:

$\frac{p - 1}{p} = 4$

Solve for p.

The numerator. difference has to be 4 times the answer of the denomiator.

So we can say

$p - 1 = 4p$

Solve for p

$- 1 = 3p$

$p = - \frac{1}{3}$

Now plug this in for the other formula.

$( \frac{ - \frac{1}{3} +1}{ \frac{1}{3} } ) {}^{2} = 2 {}^{2} = 4$

(8.218+9.93)+(17.782+0.07)

Licemer1 [7]

First, using the order of operations(PEMDAS), you would solve what is inside the parenthesis.
<span>(8.218 + 9.93) + (17.782 + 0.07)
(</span>18.148) + (17.852)
18.148 + 17.852

Now, all you would have to do is add the two sums.
18.148 + 17.852 = <span>36
</span>
The answer would be 36.

I hope this helps!
