The cost of one taco is $3.75.
We are given cost of salad, the sales tax and tip along with total expenditure. We already know, that sales tax is calculated on the cost of items. Hence, forming the equation accordingly. Let us assumed the cost of one taco be $x. So, the cost of two tacos will be $2x.
The equation will be -
2x + 2.50 + (2x + 2.50)×(6÷100) + 3 = 13.60
2x + 2.50 + (2x + 2.50)×0.06 + 3 = 13.60
Now, solving this equation to find the value of x and hence the cost of one taco.
2x + 2.50 + 0.12x + 0.15 + 3 = 13.60
Performing addition on Left Hand Side
2.12x + 5.65 = 13.60
Shifting 0.18 to Right Hand Side and performing subtraction
2.12x = 13.60 - 5.65
2.12x = 7.95
x = 7.95÷2.12
Performing division
x = 3.75
Thus, the cost of one taco is $3.75.

Answer: PR equals 6x-2 and x=6.
Step-by-step explanation: Try drawing a diagram to better visualize this, add both the equations, (2x+5)+(4x-7). Be careful of the negative, distribute properly. You should get 2x+5+4x-7 which becomes 6x-2. And finally since they have a midpoint between, both equations are equal to each other. So 2x+5=4x-7. Which should give you x=6.

Michael sold 220 candy bars to support his school band. Payday candy bars sold for $2 each and Baby Ruth bars sold for $3 each. Michael sold $600 worth of candy bars.
1. Set up the two equations that describe this situation.
2. How many Baby Ruth bars did Michael sell?
Answer:
See below
Step-by-step explanation:
Let the number of Payday be p and Baby Ruth be b
Then sub of the candy bars:
p + b = 220Payday candy bars worth ⇒ $2pBaby Ruth candy bars worth ⇒ $3bTotal ⇒ $6001. Required equations:
p + b = 2202p + 3b = 6002. Solving by substitution:
p = 220 - b, consider it in the second equation
2(220 - b) + 3b = 600660 - 2b + 3b = 600660 + b = 600b = 660 - 600b = 6060 Baby Ruth candy bars sold
a. when u and v are nonzero vectors, span{u,v} contains only the line through u and the line through v and the origin.
Span{u, v} contains the lines through u and v. But Span{u, v} also contains u + v which does not lie on either line.
A vector basic definition What is it?
A quantity or phenomena with independent qualities for both magnitude and direction is called a vector. The term can also refer to a quantity's mathematical or geometrical representation. Velocity, momentum, force, electromagnetic fields, and weight are a few examples of vectors in nature.False, If the vectors are said to span, then they encompass the area enclosed by au + bv, where a and b are real values. The line between u + v and the origin is a straightforward counterexample. This would be referred to as a plane via u, v, and the origin since it contains all possible combinations of u and v as well as multiples of each.Learn more about vector

The composite functions are listed below:
g ° f(3) = 29 g ° f(x + 1) = 2 · x² - 1 h ° g (- 3 · x) = - 36 · x - 36 f ° g (- 2 - t) = 73 + 72 · t + 16 · t² f ° g (x²) = 3 · x² + 17How to evaluate composite functions
In this problem we find five cases of composite functions, each of which has to be evaluated. A composition between the two functions f and g is defined below:
f ° g(x) = f ( g(x) )
Now we proceed to evaluate each of the five cases by using algebra properties and the definition of the composition of functions:
Case 1
g ° f(3) = g( f(3) )
g ° f(3) = 4 · (2 · 3 + 2) - 3
g ° f(3) = 4 · 8 - 3
g ° f(3) = 29
Case 2
g ° f(x + 1) = g( f(x + 1) )
g ° f(x + 1) = 2 · [(x + 1)² - 2 · (x + 1)] + 1
g ° f(x + 1) = 2 · (x² + 2 · x + 1 - 2 · x - 2) + 1
g ° f(x + 1) = 2 · (x² - 1) + 1
g ° f(x + 1) = 2 · x² - 1
Case 3
h ° g (- 3 · x) = h( g (- 3 · x) )
h ° g (- 3 · x) = 3 · [4 · (- 3 · x) - 3]
h ° g (- 3 · x) = 3 · (- 12 · x - 12)
h ° g (- 3 · x) = - 36 · x - 36
Case 4
f ° g (- 2 - t) = f( g (- 2 - t))
f ° g (- 2 - t) = [4 · (- 2 - t) - 2]² + 1 + 2 · [4 · (- 2 - t) - 2]
f ° g (- 2 - t) = (- 8 - 4 · t - 2)² + 1 + 2 · (- 8 - 4 · t - 2)
f ° g (- 2 - t) = (- 10 - 4 · t)² + 1 + 2 · (- 10 - 4 · t)
f ° g (- 2 - t) = 100 + 80 · t + 16 · t² + 1 - 20 - 8 · t
f ° g (- 2 - t) = 73 + 72 · t + 16 · t²
Case 5
f ° g (x²) = f( g(x) )
f ° g (x²) = 3 · (x² + 4) + 5
f ° g (x²) = 3 · x² + 12 + 5
f ° g (x²) = 3 · x² + 17

Yohanna is conditioning all summer to prepare for her high school's varsity soccer team tryouts. She is incorporating walking planks into her daily workout plan. Every day, she will complete six more walking planks than the day before. If she starts with two walking planks on the first day, how many walking planks will Yohanna do on the 15th day?
Answer: 86
Step-by-step explanation:
Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.
Therefore, the equation to solve this will be:
= 2 + 6d
where,
d = number of days = 14 days
= 2 + 6d
= 2 + 6(14)
= 2 + 84

Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, reflection, translation and rotation.
Given the vertices A (-4,3) B(-1,5) and C (-1,2).
If the vertices is reflected across the y = -1 line, the new location would be at:
A' (-4, -5). B'(-1, -7) and C'(-1, -4)
If it is then translated 8 units to the right i.e. (x, y) ⇒ (x + 8, y), the new location would be at:
