Answer:
da answer of da number iz 17
Answer: c. explanation: you would just use the distributive property then you would add like terms do get your answer. heres my work: -(z+1) + 2(z-2) —> -z-1 + 2z-4 —> z-5
For this case defining variables we have:
x: total amount of liters of potting soil.
y: number of liters of potting soil in each pot.
We have then to find the number of pots we use the following expression:
Substituting values we have:
Rewriting we have:
Rounding to the previous whole we have:
Answer:
Yao Xin can fill 18 pots
Answer:
x= 20,1 degrees
Step-by-step explanation:
The sum of the inner angles of a triangle is 180 degrees
So it must be
3x-11+6x-10+x = 180
added up the terms with x
10x -11-10 = 180
added up the terms without x
10x - 21 = 180
added up (21) in the two members of the equation
10x-21+21 = 180+21
10x = 201
divide the two members by 10
x = 20,1 degrees
Answer:
24.68 gram
Step-by-step explanation:
Given that :
Volume = 182.8 ml
Density of liquid = 0.135 gram/ml
Recall :
Density = mass (g/ml) / volume (ml)
Substitute the value into the equation :
0.135 = mass / 182.8
Mass = 0.135 * 182.8
Mass = 24.678 gram
Hence, weight = 24.678 grams
