Answer:
A rate: a measure, quantity, or frequency, typically one measured against some other quantity or measure.
A unit rate: 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. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
Hope this helps.
Answer:
the sum of the other two angle is 93
Step-by-step explanation:
180-87=93
Answer:
D
Step-by-step explanation:
A is not, because 2-5x = -5x+2
(nothing has changed but the order)
B is not, because 3-5+2x = 2x-2
because 3-5 = -2. so -2+2x can be rewritten as 2x-2.
C is not, because 5x-2x = 3x
because you combine like terms, and 5-2 is 3
D <em>i</em><em>s</em><em>,</em> because 2x-2+3x = 5x-2
because you combine like terms (2x+3x=5x) and -2 is left.
Answer:
1080
Step-by-step explanation:
648x2=1296÷3=432+648=1080
In this case the answer is 1/4 because she makes 2 revolutions in 8 minutes. 2/8 = 1/4
