Answer: A. -0.25
<em><u>Hope it helps :)</u></em>
Step-by-step explanation:
So since 0.75 and -1.25 are in parenthesis, u have to multiply them.
-1 (0.75 - 1.25) = 0.5
-3/4 - 0.5 = -0.25
So the answer is -0.25
Answer:
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
Step-by-step explanation:
In order to add or subtract two fractions, a common denominator is found and then the denominators of both fractions are made equal to the common denominator.
The given fractions are:
The common denominator is the number which is the multiple off denominators of both fractions involved.
Antonio made his first error in first step. Instead of finding a common multiple denominator, he add the denominator of both fractions which is wrong.
The correct method is:
Hence,
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
Answer:
y = -10
Step-by-step explanation:
−3(y+5)=15
Divide each side by -3
−3/-3(y+5)=15/-3
y+5 = -5
Subtract 5 from each side
y+5-5 = -5-5
y = -10
