Question

6= -s + 77 Given the above equation, what is the value of 1 + 5(77 - s)?

Answer 1

Answer:

1 + 5(77 - s) = 31

Step-by-step explanation:

Solve for s:

$-s+77=6\qquad\text{subtract 77 from both sides}\\\\-s=-71\qquad\text{change the signs}\\\\s=71$

Put the value of s to the expression 1 + 5(77 -s):

$1+5(77-71)$

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

$=1+5(6)=1+30=31$

Answer 2

Answer:

$\boxed{\bold{31}}$

Explanation:

Solve $\bold{6= -s + 77}$

--------------------------

Add 's' To Both Sides

= $\bold{6+s=-s+77+s}$

Simplify

= $\bold{6+s=77}$

Subtract 6 From Both Sides

= $\bold{6+s-6=77-6}$

Simplify

= $\bold{s \ = \ 71}$

Insert '71' Into 1 + 5 (77 - s)

-------------------------------

1 + 5 (77 - 71)

Solve:

77 - 71 = 6

= 1 + 5 · 6

5 · 6 = 30

= 1 + 30

= 31
