Answer:
Symmetric Property
Step-by-step explanation:
Symmetric Property, because it tells that the both sides of the equal sign are actually equal, regardless of which side of the equal sign.

If LP = 15 and PR = 9, find LR. Explain. LR = 24 because 15 + 9 = 24 according to the addition property of equality. LR = 6 because LR + LP = PR according to the Segment Addition Postulate, and 6 + 9 = 15 using substitution. LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution. LR = 6 because 15 − 9 = 6 according to the subtraction property of equality.
Step-by-step explanation:
Given,
LP = 15, PR = 9
Point P lies on the line segment PR. It would mean that,
LP + PR = LR
⇒LR = 15 + 9
⇒ LR = 24
Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.
The students at Norton School were asked to name their favorite type of pet. Of the 430ilar results, about students surveyed, 258 said that their favorite type of pet was a dog. Suppose that only 100 students were surveyed, with similar results about how many students would say that a dog is their favorite types of pet?
Answer: 60
Step-by-step explanation:
From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:
= 258/430
= 3/5
= 0.6
Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:
= 0.6 × 100
= 60

Step-by-step explanation:
Caitlyn spends $17 at the store. She buys a mop for $5 and 3 bottles of floor cleaner. If x represents the cost of each bottle of cleaner, the equation that can be used to find the value of x is 3 x + 5 = 17. Which shows the first step that should be taken to verify that $4 is the solution to the equation?
3 (4) minus 5 = 17
3 (4) = 17 + 4
3 (4) + 5 = 17 + 5
3 (4) + 5 = 17
Answer:
3(4) + 5 = 17
Step-by-step explanation:
Caitlyn spends $17. Buys mop for $5 and 3 floor cleaner. x=cleaner
3x + 5 = 17
3(4) + 5 = 17
12 + 5 = 17
17 = 17 (true)

What direction will the parent graph move if... f(x - 6) = (x - 6)
Going from f(x) = x to g(x) = f(x-6) = x-6 will move the graph 6 units to the right.
Effectively replacing x with x-6 shifts the xy axis 6 units to the left, giving the illusion the function curve shifts 6 units to the right.
Answer: shifts 6 units to the right.Which phrase should be inserted on the line to make a true statement? Use the models to help.
