Answer:
We need 5 bags of Vigoro Ultra Turf and 4 bags of Parkers Premium fertilizer.
Step-by-step explanation:
Let's first list the percentage compositions of each fertilizer type:
<u>Vigoro Ultra Turf:</u>
Nitrogen (N) = 29 kg
Phosphoric Acid (P2O5) = 3 kg
Potash (K2O) = 4 kg
<u>Parkers Premium</u>
Nitrogen (N) = 18 kg
Phosphoric Acid (P2O5) = 25 kg
Potash (K2O) = 6 kg
We can set up simultaneous equations to find out the amount of 100 kg bags of each fertilizer needed:
x = Vigoro Ultra turf (one bag)
y = Parkers Premium (one bag)
29x + 18y = 217 -Equation 1
3x + 25y = 115 -Equation 2
4x + 6y = 44 -Equation 3
Solving for x and y, we get:
x = 5
y = 4
This means we need 5 bags of Vigoro Ultra Turf and 4 bags of Parkers Premium fertilizer.
X^5 & x^5. both of the answers are the same even though the expressions were different at the start. the results relate to the addition property from multiplication (with a negative number) and the subtraction property (with positives) from division.
Answer:
Step-by-step explanation:
okay so 40 divided by 159 equals .2515 than you are going to add 159 which gives you 159.2515 and than round that to the nearest 100
Answer:
90
Step-by-step explanation:
If the original price of a bracelet was a
70%a = 63
70/100a = 63
a = 63 × 100/70
a = 90
Answer:
slope of line one: 2/4 or 1/2
line two: 6/1
line 3: 6/3 or 2
line 4: -4/1
to find the slope of a line, you have to use rise/run the number of space going along the y-axis is the rise, and the space of the points on the x-axis is the run.
hope this helps!
