Answer:

1.The formula to convert Celsius to Fahrenheit is:

F = 1.8 C + 32

Multiply the Celsius temperature by 1.8.

Add 32 to this number.

Report the answer in degrees Fahrenheit.

Example: Convert 20°C to Fahrenheit.

F = 1.8 C + 32

F = 1.8 (20) + 32

1.8 x 20 = 36 so F = 36 + 32

36 + 32 = 68 so F = 68°F

20°C = 68°F

Louise has only 5 cent, 10 cent, and 20 cent coins in her purse. She has 30 coins in total, and she has two more 10 cent coins t

Hoochie [10]

Let x = number of 5 cent coins.
Then there are (x+2) 10 cent coins.
Let y = 20 cent coins.
Total coins: x+(x+2)+y = 30
2x+y=28
y = 28-2x (1)
Total value: 0.05x + 0.1(x+2) + 0.2y = 3.80
0.15x + 0.2y + 0.2 = 3.80
0.15x + 0.2y = 3.60 (2)
Substitute (1) into (2).
0.15x + 0.2(28-2x) = 3.60
-0.25x + 5.60 = 3.60
2.00 = 0.25x
8 = x

From (1), obtain y = 28 - 2(8) = 12
Answer: (x+2) = 8+2 = 10
Louise has 10 10-cent coins
