Dhanraj spent $204.20 purchasing volleyballs and basketballs.

Lemur [1.5K]

Answer:

Number of volleyballs bought = 8

Number of basketballs bought = 11

Step-by-step explanation:

Given that:

Total amount spent = $204.20

Let,

x be the number of volleyballs

y be the number of basketballs

According to given statement;

y = x+3 Eqn 1

8.20x+12.60y=204.20 Eqn 2

Putting value of y from Eqn 1 in Eqn 2

8.20x + 12.60(x+3) = 204.20

8.20x + 12.60x + 37.80 = 204.20

20.80x = 204.20 - 37.80

20.80x = 166.40

Dividing both sides by 20.80

$\frac{20.80x}{20.80}=\frac{166.40}{20.80}\\x=8$

Putting x=8 in Eqn 1

y = 8+3 = 11

Hence,

Number of volleyballs bought = 8

Number of basketballs bought = 11

Alisiya [41]

1,969.35.
first you add them all up (6.45+150+500)=656.45, which is how much he rode in 1 day, no you multiply it by 3. so 3(656.45)=1,969.35 so thats how many km he rode in three days

Convert degrees Fahrenheit (F) into degrees Celsius (C) using the formula C = 5/9(F - 32). Rewrite the equation to convert degre

marissa [1.9K]

To answer the question above, isolate F on the other side of the equation by multiplying both sides by 9/5. This gives,
(9/5) C = F - 32
Next, transpose -32 to left side.
(9/5)C + 32 = F
Rearrange the equation to give an answer of
F = (9/5)C + 32
