Answers

Answer 1
Answer:

The prices of RacerZ and the Swiftee bicycles are $142 and $154.78.

What is multiplication?

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.

Answers

400 + (n-1) (-5) = 322 + (n-1) (-3)
-5n + 5 = 322 
-3n + 3    | 405 - 5n
               =325 - 3n
80=2n
n=40            n - 1 = 39    

 Answer = 39 , 39 weeks until they weigh the same

How do you set up this equation ?

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.

$\Rightarrow (9y)/(9) =(45)/(9)

y = 5

The value of y is 5.

Jessie drives 6 3/8 miles in a golf cart during a round of golf. Payton drives 7 3/4 miles. How much farther does Payton drive?

Answers

Payton drives  7 3/4
and Jessie drives 6 3/8
to find how much farther Payton drives subtract them
7 3/4 - 6 3/8
find the LCD or least common denominator in the fractions 
3/4 = 6/8 so now you have
7 6/8  - 6 3/8
7-6 = 1
6/8 - 3/8 = 3/8
gives you 1 3/8 miles farther
