Khadra spent $20 on some healthy snacks. Each apple costs $2 and each orange cost $4. She bought a
total of 8 snacks.

1. Write 2 equations to model this scenario.

2. Find the total number of apples that Khadra bought using the substitution method.

Answers

Answer 1

Answer:

2 + 2 + 2 + 4 + 4 + 4= 20          3 apples and 4 oranges

Step-by-step explanation:

20 - 4 = 16     16 - 4 =      14 - 2 = 12      12 - 4 = 8       8 - 4 = 4        4 - 2 = 2

1 orange   2 oranges     1 apple         3 oranges           4 oranges      2 apples

and 2 - 2 = 0

     3 apples

Jay organised a large wedding and 1/3 of them chose beef 5/12 of them chose Chicken and 69 of them chose vegetarian so how many guest were at the wedding ?

Answers

Answer:

276 Guests

Step-by-step explanation:

Calculation to determine how many guest were at the wedding

Guests that choose beef =1/3

Guests that choose chicken= 5/12

Guests that choose vegetarian=69

Now let calculate the how many guest were at the wedding

Let x represent the numbers of guest that were present at the wedding

Hence,

x/3 + 5x/12 + 69 = x

9x/12 + 69 = x

12x/12 - 9x/12 = 69

3x/12 = 69

x/4 = 69

x=69*4

x = 276 guests

Therefore the numbers of guests that were at the wedding is 276

Answer: 276

Step-by-step explanation: Let “x” be the number of guest.

1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276

1/3(276) + 5/12(276) + 69 = 276

92 + 115 + 69 = 276

Answers

Answer: y=5/3x-4

Step-by-step explanation:

Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).

y=mx+b (Or some people prefer y=ax+b, but the same thing).

Now, plug in the x and y values, getting:

6 = 6m+b and -4=0*m+b

When you simplify, you will get that b is -4, and then m is 5/3

So the equation is y=5/3x-4

You can plug the numbers of x and y in to check your answer.

Hope this helps!

Eq 1: 2x -4y = -2, Eq 2: 3x + y =4

Answers

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x - 4y = - 2 → (1)

3x + y = 4 → (2)

Multiplying (2) by 4 and adding the result to (1) will eliminate the y- term

12x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

14x + 0 = 14

14x = 14 ( divide both sides by 14 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

3(1) + y = 4

3 + y = 4 ( subtract 3 from both sides )

y = 1

solution is (1, 1 )

Write the number using scientific notation:
23,000

Answers

The scientific notation is 2.3 x 10^3

The scientific notation representation of 23,000 is 2.3 x 10⁴

To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.

Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.

Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.

Answers

Answer:

x=2, y = -4.

or as an ordered pair it is (2, -4).

Step-by-step explanation:

-x + 6y = -26

x + 5y =  -18      Add these 2 equations to eliminate x:

0 + 11y = -44

y = -44/11 = -4.

Now substitute y = -4 in the first equation:

-x + 6(-4) = -26

-x - 24 = -26

-x = -26 + 24 = -2

x = 2.

Check the result by substituting in equation 2:

x + 5y = 2 + 5(-4) = 2 - 20 = -18  - checks out.
