Answer:
multiplication property of equality
Step-by-step explanation:
since it is x/6=7 you need to multiply 6 to both sides in order to find the solution, which is 42.
Answer:2/5
Step-by-step explanation:8 out of 20 marbles reduces down to 2/5.
True, they exist in exactly one plane
For the first problem the answer is -5/2
2x−7+10=−2
Step 1: Simplify both sides of the equation.
2x−7+10=−2
2x+−7+10=−2
(2x)+(−7+10)=−2
(Combine Like Terms)
2x+3=−2
Step 2: Subtract 3 from both sides.
2x+3−3=−2−3
2x=−5
Step 3: Divide both sides by 2.
2x/2=−5/2
x=−5/2
Answer:
x= -5/2
