Let’s solve the equation
0.5(5x+1) = 3
= 2.5x + 0.5 = 3
= 2.5x = 3 - 0.5
= 2.5x = 2.5
= x = 1
Hope it helped !!!

Answer:
-13/6 or (in mixed number form) -2 1/6
Step-by-step explanation:
Rewriting our equation with parts separated
=10+512−12−712
Solving the whole number parts
10−12=−2
Solving the fraction parts
512−712=−212
Reducing the fraction part, 2/12,
−212=−16
Combining the whole and fraction parts
−2−16=−216
Another way to do it:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
125/12−151/12
Applying the fractions formula for subtraction,
=(125×12)−(151×12) / 12×12
=1500 − 1812/ 144
=−312/144
Simplifying -312/144, the answer is
=−2 1/6
Answer:
- 2 and 7
Step-by-step explanation:
A polynomial P(x) divided by (x + h) has remainder f(- h) ← remainder theorem
P(x) divided by (x + 5) has remainder P(- 5) = - 2 ( from result given )
P(x) divided by (x - 3) has remainder P(3) = 7 ( from result given )
About 15.7, or 16 if you're looking for a whole number.
