Answer:
let mother's age y and daughter age x
a/q y=3x and y-5=5x-25
put y in second eq we get x=10 &y=30(their present age)
Answer:
Right, Isosceles
Step-by-step explanation:
The side lengths of this triangle : 2√8 2√5 2√5
Scalane triangle has all side lengths in different measure but in this triangle we have two side lengths equal
Right triangle has a right angle with 90° and the square measure of hypotenuse is equal to sum of the square length of two side lengths in this triangle since 2√5 + 2√5 = 2√8 we can say that this is a right triangle.
Isosceles triangle are triangles with two side lengths equal to each other
Equilateral triangles are triangles with all side lengths equal to each other but we know one of the side length in this triangle is different
so the answer is Right and Isosceles.
Hello from MrBillDoesMath!
Answer:
The first choice, Pi + (-Pi) = 0
Discussion:
Pi is an irrational number. Saying the irrational numbers <u>are</u> closed under addition means if we add two irrational numbers we will get another irrational number. In our case, Pi + (-Pi) = 0, which is correct, BUT 0 is a <u>rational </u>number. This shows the set of irrational numbers is NOT closed under addition.
Thank you,

You would set it up like this: 150x + 280 = 255x The you just solve.
