Q. Select all of the equations below that are equivalent to:b+c=−25Use properties of equality.Multi-select Choices:(A)−4(b+c)=100(B)(b+c)⋅−2=50(C)(b+c)⋅−3=75(D)3(b+c)=−75
Given Equation: We are given the equation b+c=−25. We need to determine which of the multiple-choice options are equivalent to this equation by using properties of equality.
Check Option (A): Let's start with option (A): −4(b+c)=100. To check if this is equivalent, we can divide both sides of the equation by −4 to see if we get the original equation.−4(b+c)/−4=100/−4b+c=−25This is equivalent to the original equation.
Check Option (B): Now, let's check option (B): b + c) \cdot (–2) = 50\. We can divide both sides by \$–2 to see if it simplifies to the original equation.(\newline\)(b + c) \cdot (–\(2) / (–2) = 50 / (–2)(\newline\)\b + c = –25(\newline\)This is also equivalent to the original equation.
Check Option (C: Next, we check option (C): b + c) \cdot (–3) = 75\. We divide both sides by \$–3 to check for equivalence.(\newline\)(b+c)⋅(–3)/(–3)=75/(–3)(\$b + c = –25(\newline\)This is not equivalent to the original equation because the correct division should give us \$b + c = –25\).
