Answer: x=11
Step-by-step explanation:
First distribute 3 to both x and -3.
3x-9=24
Then add 9 to both sides to leave the x on its own.
3x=33
Divide by 3 on both sides.
X=11
Answer:
The correct option is the second option;
a. Division property of equality
b. Symmetric property of congruency
c. Multiplication property of equality
Step-by-step explanation:
a. For the equation in part a., we have;
6·a = 30
Therefore;
6·a/6 = 30/6
a = 5
Which is of the form, if a = b then a ÷ c = b ÷ c, which is the division property of equality
b. For the relationship in part b., we have;
∠ABC ≅ ∠LMN
∠LMN ≅ ∠ABC
The above relationship is of the form, if a ≅ b then b ≅ a, which is the symmetric property of congruency
c. For the equation in part c., we have;

Multiply both sides by 3, to get;

Cancel like terms on the left hand side of the equation, to get;
2·(x - 6) = 24
Which is of the form, if a = c, then a × c = b × c which is the multiplication property of equality
Let s be the son's age 15 yeasr ago and m the mother's age that year.

We also know that:

Plotting vallues:

Remember that they were that age 15 years ago.
So their actual age is 30 and 60.
