Layla is baking a Double Chocolate Chocolate Chip cake. For this recipe, she will need one bag of flour and a number of bags of chocolate chips. At the grocery store, she sees that a bag of flour costs $3.59 and each bag of chocolate chips, c, costs $2.75. Write an algebraic expression to represent the total amount she will spend at the store.

Answer:

81 adult tickets

Step-by-step explanation:

Step 1:

Set up a system of equations

Since the adult tickets and student tickets add to 243, we can do

[tex]a+s=243[/tex]

and the student tickets sold were 2x the adult tickets, we can do

[tex]s=2a[/tex]

We can replace s in the first equation adding to 243 with 2a

[tex]a+s(2a)=243\\3a=243\\[/tex]

Step 2:

Solve for a. We can divide both sides by 3.

[tex]a=81[/tex]

Therefore, there were 81 adult tickets sold.

Step 3:

We can check our work! Since we learned earlier the student tickets are 2x adult tickets, we can multiply 81 by 2 and add that to 81 to see if it equals 243!

[tex]s=2a\\s=2(81)\\s=162[/tex]

And...

[tex]162+81=243[/tex]

So, 81 must be the answer!

Answer:

(x + 45) - (1.5x - 12) = 17

Step-by-step explanation:

The number of waffles there were initially is; 80 waffles

Let the number of pancakes be x.

Let the number of waffles be y

Hence, after she baked 45 more waffles, and her grandchildren eat 12 pancakes, what she has is;

There were 17 more waffles than pancakes.

Using a system of equations, it is found that Ajay is 25 years old today.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Wale was twice as old as Ajay 10 years back, hence:

[tex]x - 10 = 2(y - 10)[/tex]

[tex]x - 10 = 2y - 20[/tex]

[tex]x = 2y - 10[/tex]

Wale will be 40 years old in 10 years, hence:

[tex]x + 10 = 40[/tex]

[tex]x = 40[/tex]

Then, Ajay's present age is found as follows.

[tex]2y = x + 10[/tex]

[tex]2y = 40 + 10[/tex]

[tex]y = \frac{50}{2}[/tex]

[tex]y = 25[/tex]

Based on the system of equations, it is found that Ajay is 25 years old today.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

Based on the given information, we can say

Let Wale's age be x

Let Ajay's age be y

Ten years ago,

Wale = x - 10

Ajay = y - 10

If wale was twice as old as Ajay 10 years back, then;

x - 10 = 2(y - 10)

Since Wale will be 40 years old in 10 years, then;

x + 10 = 40

x = 40 - 10

x = 30

Recall that x - 10 = 2(y - 10)

30 - 10 = 2(y - 10)

20 = 2(y-10)

y = 20

Hence Ajay will be 20 years old today

Answer:

Step-by-step explanation:

You need to concern yourself with the +3. That will determine what the equal roots are.

(2x + √3)^2

Now expand this to see what p is. (Kind of a nasty question if you ask me).

4x^2 + 2x*√3 + (√3)^2

4x^2 + 2√3 x + 3                 also possible is

4x^2 - 2√3 x + 3

So the answer is p = 2√3

The answer could also be p = -2√3

Answer:

  p = ±4√3

Step-by-step explanation:

The discriminant of quadratic equation ax²+bx+c = 0 is ...

  d = b² -4ac

In your quadratic, its value is ...

  d = p² -4(4)(3) = p² -48

The discriminant will be zero when the quadratic has equal roots. In that case, the values of p are found by ...

  d = 0

  p² -48 = 0

  p² = 48 . . . . . add 48

  p = ±√48 . . . . take the square root

  p = ±4√3 . . . . simplify

__

Another way to get there is by looking at the factoring of a quadratic with equal roots:

  (ax +b)² = 0 = a²x² +2ab +b²

Comparing to the given quadratic, we find ...

  a² = 4   ⇒   a = ±2 . . . . . . coefficient of x²

  b² = 3   ⇒   b = ±√3 . . . . constant

  p = 2ab = 2(±2)(±√3) . . . . coefficient of x

  p = ±4√3

The answer is 6 ft.

Step-by-step explanation:

Step-by-step explanation:

Given:

log_(a) abc = x+1,

log_(b) abc = y+1,

log_(c) abc =z+1

Asked: x + y + z + 2 = ?

Solution:

Let

log_(a) abc = x+1 ⇛log_(abc) a = {1/(x+1)} →→→Eqn(1)

log_(b) abc = y+1 ⇛log_(abc) b = {1/(y+1)} →→→Eqn(2)

log_(c) abc = z+1 ⇛log_(abc) c = {1/(z+1)} →→→Eqn(3)

On adding equation (1),(2) and (3) then

log_(abc) a + log_(abc) b + log_(abc) c = {1/(x+1) + {1/(y+1)} + {1/(z+1)}

⇛log_(abc) abc = {{(y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)}/{(x+1)(y+1)(z+1)}]

⇛1 = {{(y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)}/{(x+1)(y+1)(z+1)}]

⇛{(x+1)(y+1)}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛{x(y+1)+1(y+1)}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛{xy + x + 1 + y}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛{xy + x + y + 1}(z+1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛z(xy + x + y + 1) + 1(xy + x + y + 1) = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛xyz + xz + yz + z + xy + x + y + 1 = (y+1)(z+1) + (z+1)(x+1) + (x+1)(y+1)

⇛xyz + xz + yz + z + xy + x + y + 1 = y(z+1)+1(z+1) + z(x+1)+1(x+1) + x(y+1)+1(y+1)

⇛xyz + xz + yz + z + xy + x + y + 1 = yz + y + z + 1 + xz + z + x + 1 + xy + x + y + 1

⇛x+y+z = y + z + 1 + x + 1

⇛x+y+z = x + y + z + 2

Therefore, x + y + z + 2 = x + y + z

Answer: Hence, the value of x + y + z + 2 = x + y + z.

Answer:

Tennessee

Step-by-step explanation:

First, let's find out how much tax he paid...

$695.49-$649.99=$45.50

We can use this to set up an equation...

x%(649.99)=45.50

We can convert x% to x/100 since any percentage is just that number over one hundred...

[tex]\frac{x}{100}*649.99=45.50\\\\\frac{649.99x}{100}=45.50[/tex]

Multiply 100 to both sides

[tex]649.99x=4550[/tex]

Divide both sides by 649.99

[tex]x$\approx$6.92[/tex]

This is closest to 7 (our answers is not exact since you can only have two decimal places in money), therefore he lives in D. Tennessee
