(2x+1)+(x-10)=90\\\\(2x+x)+(1-10)=90\\\\3x-9=90\ \ \ |+9\\\\3x=99\ \ \ |:3\\\\x=33^o

Yes. The equation make sense. It's has the solution.

x=33^o\\\\2x+1=2(33)+1=67^o\\\\x-10=33-10=23^o

I need help now I don't get this
Darina [25.2K]
The answer is $1.80.  You would take 25% of 3, which is 75, and subtract it from 3.  That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25.  That leaves you with a grand total of $1.80.  Hope that this helped!

Find a formula for the number of patrons as a function of profit.
Solnce55 [7]
Here is my answer. Let just give assumptions. For example,the relationship is linear.Therefore the slope, "m," is the same throughout.
Let us make patrons the independent variable, the two points are: (1314, 11333) and (1544, 13518).
m = (13518-11333)/(1544-1314)
m = 9.5
 
profit = 9.5 patrons (you pick the variable names)
For 1 more patron substitute 1:
profit = 9.5 (1)
profit = 9.5
 
Isolate "patrons" and you get the function based on profit:
patrons = profit/9.5
 
The break even point is for 0 < profit.
0 < profit = 9.5 patrons
0 < 9.5 patrons
0 < patron

Please answer Thank you please answer hurry PLease

Answer:

$(80.5x + 69)

Step-by-step Explanation:

Recall, distributive property of multiplication can simply be expressed as follows, x(y + z) = xy + xz or x(y - z). Where x, y, and z could be any number.

Now, let's use the distributive property to show the total costs of plants Gloria decides to buy as an expression and also simplify it.

Thus, Gloria buys:

4 ferns = 4(0.5x - 3) = 4(0.5x) - 4(3) = $(2x - 12)

2 palms = 2(10x - 2.50) = 2(10x) - 2(2.50) = $(20x - 5.00)

10 lilies = 10(5 + 0.25x) = 10(5) + 10(0.25x) = $(50 + 2.5x)

8 shrubs = 8(4.50 + 7x) = 8(4.50) + 8(7x) = $(36 + 56x)

Total cost of the plants = (2x - 12) + (20x - 5) + (50 + 2.5x) + (36+ 56x)

Open the parentheses and then simplify:

Total cost = 2x - 12 + 20x - 5 + 50 + 2.5x + 36 + 56x

= 2x + 20x + 2.5x + 56x - 12 - 5 + 50 + 36

Total cost = $(80.5x + 69)
