Answer:
It means that above 0 degrees Celsius the water does not freeze, whereas 0 degrees are freezing teperatures of water.
Step-by-step explanation:
Water freezes at 0 degrees Celsius, but the freezing temperature can be lowered by adding salt to the water. A student discovered that adding half a cup of salt to a gallon of water lowers its freezing temperature by 7 degrees Celsius. What is the freezing temperature of the gallon of salt water?
0° - 7° = -7°
Answer:
Triangle b = 4, h = 7
Step-by-step explanation:
Rectangle area = L*W
Triangle area = (B*H)/2
Rectangle/2 = Triangle
If you want triangle to = rectangle, then rectangle*2/2
Rectangle = 4*3.5 = 14
Triangle = 4*7 = 28/2 = 14
Answer: d) 3 hours.
Step-by-step explanation:
Let x be the required number of hours for which the total fee charged by the companies the same.
Given: Peppy Pets charges a flat fee of $15 plus $3 per hour .
So Total charge = 15+3x ( in dollars)
Happy Hounds charges a flat fee of $21 plus $1 per hour.
So Total charge = 21+x ( in dollars)
When the total charge for both companies are the same, then
Hence, the correct option is d) 3 hours.

-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
