Answer:
no
Step-by-step explanation: You can use variables to find that out. PEMDAS works too (parenthesis, exponents, multiplication, division, addition, subtraction). Put a random number for x and then you can see that it is not equivalent. Example: 30 - 10x7 = 40 but 10 (30-70) = -400
Answer:
-n⁴ + 4n
Step-by-step explanation:
Step 1: Write expression
(3n⁴ + 6n + 6n) - (n + 4n⁴ + 7n)
Step 2: Combine like terms
3n⁴ + 12n - (4n⁴ + 8n)
Step 3: Distribute -1
3n⁴ + 12n - 4n⁴ - 8n
Step 4: Combine like terms
-n⁴ + 4n
C. 200
They earn $2.50 per box of markers, meaning that to make $500 they have to sell 200. [500/2.5=200]
Answer:
He can feed 200 plants
Step-by-step explanation:
To solve this, we will follow the step below:
first, convert 25 g to kg
25 g = 25/1000 = 0.025 kg
Now using proportion to solve;
Let x be the number of food plant he can feed the plant
0.025 kg = 1
5 kg = x
cross-multiply
0.025×x = 5×1
0.025x =5
Divide both-side of the equation by 0.025
0.025x/0.025 = 5/0.025
x=200 plants
Therefore, he can feed 200 plants
-x-1
all you do is subtract 9x from 8x.
