The cost for one steak burger is $4.5. The price/ The cost of one order of fries is $2.25

Let one steak burger cost $x

and one fries order cost $y

Hence, we have

3x+2y = 18-----------1

2x+3y = 15.75-------2

multiply equation 1 by 2 and equation 2 by 3

6x + 4y = 36 ---------3

6x +  9y = 47.25 ----4

subtraction 4 from 3 we have

0x -5y = -11.25

Divide both sides by -5

y = 11.25/5

y = $2.25

Put y = 2.25 in equation 1 to find x

3x+2(2.25) = 18-----------1

3x + 4.5 = 18

3x = 18 -4.5

3x = 13.5

x = 13.5/3

x = $4.5

Using factorization method;

x²+13x+40=0

x²+13+40

Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).

The two numbers are +5 and +8

The equation will therefore be = x²+5x+8x+40

You'll then factorize (I.e use a common factor of both values to bracket them)

x(x+5)+8(x+5)

(x+8)(x+5)

x is therefore (x+8=0) or (x+5=0)

x=(x=0-8) or (x=0-5)

x= -8 or x= -5

Answer:

a₃ = 135

Step-by-step explanation:

using the recursive rule and a₁ = [tex]\frac{5}{3}[/tex] , then

a₂ = a₁ × - 9 = [tex]\frac{5}{3}[/tex] × - 9 = 5 × - 3 = - 15

a₃ = a₂ × - 9 = - 15 × - 9 = 135

Answer:

135

Step-by-step explanation:

since this is a recursive formula it shows that 5/3 is our 1st term and the common ration is -9 see: Step 1. a(1)=5/3  a(2) = Step 2. a(1)x-9=-15

Step 3. a(3) = -15x9=135 i hope this helps :D bye have a good day!!!!

Answer:

12 km

Step-by-step explanation:

going east by 5 km and then west by 5 km brings him 12 km to the north of where he started

Freddie's displacement is a vector with a length of 12 km pointing straight up (in the positive y direction).

Displacement is the distance between the final point and the initial point.

We have,

Freddie's distance traveled is the total length of the path he took, regardless of direction.

To find the distance, we can use the Pythagorean theorem, since he moved in a right-angled triangle:

distance = √(5² + 12² + 5²) = √(25 + 144 + 25) = √194 ≈ 13.928 km

So Freddie's distance traveled is approximately 13.928 km.

Freddie's displacement is the straight-line distance and direction from his starting point to his ending point.

We can represent his movements using vector notation:

East: 5 km to the right = +5 km in the x direction

North: 12 km upwards = +12 km in the y direction

West: 5 km to the left = -5 km in the x direction

The total displacement is the vector sum of these three movements. To calculate this, we can add up the x components and y components separately:

x displacement = +5 km - 5 km = 0 km

y displacement = +12 km

Thus,

Freddie's displacement is a vector with a length of 12 km pointing straight up (in the positive y direction).

Answer:

we know,

area of circle = πr²

area of semicircle of circle having diameter of 16.

according to formula = πr²

radius = 16/2 = 8 cm

22/7 × (8)² → 22/7 × 64 → 1408/7 = 201.14/2 = 100.57 cm (approx.)

area of semicircle of circle having diameter of 20 cm.

22/7 × 20² = 22/7 × 400 = 8800/7 = 1257.14/2 = 628.57

to get the area of shaded part 628.57 - 100.57 = 528 cm² (approx.)

The arrangement of the apples in the stack is in a sequence that can be

used to find the number of apples in each row and in the stack.

Correct response:

The given parameters are;

Dimensions of apples in the rectangular base = 7 apples by 5 apples

Number of apples on which each apple above rests = 4 apples

Required:

The number of apples in the stack.

Solution:

The dimensions, length and width of the apples in each row decreases

by 1 compared to the row on which the apple rests, as follows;

In the base, the dimension = 7 by 5

In the row directly above, the dimension = (7 - 1) by (5 - 1)

The number of apples sequence continues and is completed by a singles row of apples at the top, from which gives;

Number of apples in the stack = 7 × 5 + 6 × 4 + 5 × 3 + 4 × 2 + 3 × 1 = 85

Hi!

In the screenshot provided, the first graph has a positive slope, but in the second graph, the slope is negative.

Here's why:

When trying to find out if the slope is positive or negative, you look to see which direction the line in pointing.

In this case, in graph one, the line is going up so this means that the slope is positive. In graph two, the line is going down, so this means that the slope is negative.

Answer:

22

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable. x = 22

Answer:

22

Step-by-step explanation:

The diagonals are divided into 2 parts. They're both equal to each other in order to equal the total length.

Setting them up to equal each other is the easiest way to solve.

2x + 18 = x + 40.

Now with simple algebra, we can find the sidelength of x.

Subtract both sides by x.

x + 18 = 40

Subtract both sides by 18.

x = 22.

Answer:

1/6

Step-by-step explanation:

When the y is isolated on one side and is not multiplied by anything (other than one), the slope is the value before the x. In this case, it's 1/6. And in if y is perfectly isolated, then the y-intercept is the value after the x, which is positive 3/2 in this case.
