5(x-7)=55 5x-35=55 5x=90 x=18 Which property was used to write the equation in step 2?
@hughesy123
Is this multiple choice? If so, can you provide the answers?
distributive property addition property of equality subtraction property of equality division property of equality
It is the distributive property :) Thats because they distribute 5 over x and 7.
-5(a+3)=-55 what is the value of A My guess is 14 but here are the options -14 -8 8 14
-5(a+3)=-55 -5a+(-15)=-55 -5a=-40 a=8
1/2(x+6)=18 What is the value of x? 6 7 1/2 14 1/2 30
my guess is 6 it makes the best since to me
1/2(x+6)=18 1/2x + 3=18 1/2x=15 x=7.5 or 7 1/2
2.5x=5.7 Which method should be used to solve for x? distributive property addition property of equality combining like terms division property of equality
last one plz.!;3
The correct answer is Division Property, since you would divide 2.5 across the = sign in order to find x.
