Answer:
n=3 5/7
Step-by-step explanation:
8(n+7) Multiply each term in the parenthesis by 8
8n + 8 x 7
8n + 56
4 - 6n = 8n + 56
move variable to the left by adding its opposite to both sides
-6n - 8n + 4 = 8n - 8n +56
eliminate the opposites
-6n - 8n + 4 = 56
collect like terms by calculating the sum or difference of their coefficients
-6n - 8n
(-6 - 8)n
calculate the difference
-14n
divide both sides of the equation by -14
-14n / (-14) = 52 / (-14)
n = 52 / (-14)
n = -52/14
n= -26/7
alternative form of writing the answer is
n= -3 5/7 or n= 3.71429
Answer:
241
Step-by-step explanation:
= 5^2 + (10 -7)^3 x 2^3 ^ = exponent
= 10 - 7 = 3
= 25 + 3^3 x 2^3
Calculate the exponents
= 25 + 27 x 8
= 27 x 8 = 216
= 25 + 216
= 241
Answer is 241
