Juanita has saved 35% of the money for a bike. She has saved $63 dollars. How much does the bike cost?
lara [203]

Answer:

The total cost of the bike is $180.

Step-by-step explanation:

Given that Juanita has saved 35% of the money for a bike.

Let the total cost of the bike = x

As she has saved $63 dollars which represents the 35% of the money for a bike.

In other words, 35% of the total cost is $63 dollars.

As the total cost = x

Thus,

35% of x = 63

\frac{35}{100}x=63

Multiply both sides by 20

20\times \frac{35}{100}x=63\times \:20

simplify

7x=1260

Divide both sides by 7

\frac{7x}{7}=\frac{1260}{7}

Simplify

x=180 $

Thus, the total cost of the bike is $180.

I'll mark brainliest! Please help me, i'm desperate for an explanation lol!
borishaifa [10]

Answer:

Question 1: x = -75/38

Question 2: -5/6 X (-5/8) X 6/5 = 5/8

Step-by-step explanation:

Question 1:  3 4/5x - 2 1/2 for x = -10

Given equation is in whole number form so by simplifying we get:

19/5x - 5/2 = -10            (As 5*3 + 4 = 19  and 2*2+1 = 5)

Now Add 5/2 on both sides we get:

19/5x - 5/2 +5/2 = -10 + 5/2

19/5x  = -10 + 5/2

Taking LCM we get:

19/5x = (-20+5)/2

19/5x = -15/2

Multiply both sides by 5/19

x = -15/2 * 5/19

x = -75/38

Question 2:

= -5/6 X (-5/8) X 6/5

Multiplying first 2 fractions we get:

= 25/48 X 6/5   ("-" multiplied by "-" gives "+")

  • 25 in numerator will be cancelled from 5 in denominator giving 5
  • 6 in numerator will be cancelled by 48 in denominator giving 8

= 5/8 X 1/1

Multiplicative identity

= 5/8

I hope it will help you!
