To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter C.
Answer:
-9.8n + 11.1
Step-by-step explanation:
1. Combine like terms
-5.8n - 4n = -9.8n
3.1 + 8 = 11.1
2. -9.8n +11.1
Answer:
90 percent
Step-by-step explanation:
15 divided by 4 so 3.75 i rounded it and i got 4
In a quadratic equation with the general formula of:
ax^2 + bx + c = 0
The discriminant is equal to b^2 - 4(a)(c). If the answer is a perfect square, then there are two real numbers. If not, then there are no real number root.
The discriminant for this equation is
(-6)^2 - 4(3)(1) = 24
Since 24 is not a perfect square, there are no real number roots.
Answer:
150
Step-by-step explanation:
100% represents 500 jars
Subtract the sum of the percentage of other jars for percent of blue jars
100 - (30 + 25 + 15) = 100 - 70 = 30%
That is 30% of the jars are blue
Calculate 30% of 500 to obtain number of blue jars
30% = 
= 0.3, hence
number of blue jars = 0. 3 × 500 = 150
