If x = -10 and x + √7 - 7p = -3 solve for p

Hence, in the given expression,  p  =  -0.6220

Step-by-step explanation:

Here, the given expression is:

x = -10 and

x + √7 - 7 p = -3

Now, substitute x = -10 in the second equation, we get:

x + √7 - 7 p = -3  ⇒ -10 + √7 - 7 p = -3

Substituting √7 = 2.645751

Solving, it further, we get

-10 + √7 - 7 p = -3

-10 + 2.645751  + 3  = 7 p

or,   -4.354248  =  7 p

or,  p =  -4.354248/7 =  -0.6220

or, p  =  -0.6220

Hence, in the given expression, p  =  -0.6220

145÷7.25 = 20

Step-by-step explanation:

This is a simple division of numbers with decimals.

Here we have dividend ( the number to be divided) (or numerator) = 145

and divisor (the number which divides dividend) (or denominator)= 7.25

Now, in case of decimals in denominator, we add number of zeroes in numerator equal to number of digits after decimal point in denominator, and thus the decimal point gets removed. So, this gives us 14500÷725, which by simple calculation is equal to 20.
