Multiply or divide normally. Whenever the signs are different it’s always gonna be a negative.
A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
Some examples of rate include cost rates, (for example potatoes cost R16,95 per kg or 16,95 R/kg) and speed (for example, a car travels at 60 km/h). When we calculate rate, we divide by the second value, so we are finding the amount per one unit.
A=6
B= -1/2
C= 11
I had this one on my test and I got it right have a good day
Since the area of a square is side squared, you can find the length of each side by finding the square root of the area, which is 5. Since there are four sides in a circle, just multiple 5 by 4 and your answer is 20 units.
Answer:
t≤ 8/5
Step-by-step explanation:
-4t≥-2/5 (at last means greater than or equal to }
multiplying by -1
when we multiply or divide by negative number sign of inequality changes
4t≤2/5
t≤4(2/5)
t≤ 8/5
