Bonus Question

Mathematics
1 answer:
Sedbober [7]3 years ago
8 0

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:

4

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

So

(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!
