The prices of RacerZ and the Swiftee bicycles are $142 and $154.78.
In Maths, the basic explanation of multiplication is adding a number, with respect to another number, repeatedly.
Given that, The Speed monster's price is $64.80. The RacerZ is $20 less than 2.5 times the price of the Speed monster. The Swiftee is 1.09 times the price of the RacerZ.
According to question,
Price of RacerZ = 2.5*64.80-20 = $142
Price of Swiftee = 142*1.09 = $154.78
Hence, The prices of RacerZ and the Swiftee bicycles are $142 and $154.78.

Given:
Quadrilateral PQRS is a rhombus.
To find:
The value of y.
Solution:
In the rhombus PQRS,
PS = 10y and SR = y + 45
Property of rhombus:
All sides are congruent.
⇒ PS = SR
⇒ 10y = y + 45
Subtract y from both sides.
⇒ 10y - y = y + 45 - y
⇒ 9y = 45
Divide by 9 on both sides.
⇒ y = 5
The value of y is 5.
the answer is 15. 15.4 is closer to 15 than 16
