<u>Answer</u><u> </u><u>:</u>

  • The school cafeteria sold 35 vegetable wraps.

<u>Step-by-step explanation:</u>

  • Let the count of vegetarian wraps be x
  • Let the count of chicken wraps be y.

<u>Then</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>count</u><u> </u><u>we</u><u> </u><u>have</u><u> </u><u>:</u>

→ count of vegetarian wraps + count of chicken wraps = 103

→ x + y = 103......[Equation (i)]

<u>Then</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>cost</u><u> </u><u>we</u><u> </u><u>have</u><u> </u><u>:</u>

→ ❲$1.00 * x❳ + ❲$3.40 * y❳ = $266.20

<u>Dropping the dollar signs we get :</u>

→ ❲1.00 * x❳ + ❲3.40 * y❳ = 266.20

→ x + 3.40y = 266.20.....[Equation (ii)]

<u>Substr</u><u>acting</u><u> </u><u>equation</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>from</u><u> </u><u>equatio</u><u>n</u><u> </u><u>(</u><u>ii</u><u>)</u><u> </u><u>we</u><u> </u><u>get</u><u> </u><u>:</u>

→ 0 + 2.4y = 163.2

→ 2.4y = 163.2

→ y = 163.2 ÷ 2.4

→ y = 68

<u>Now</u><u>,</u><u> subsitute</u><u> </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>6</u><u>8</u><u> </u><u>in</u><u> </u><u>equatio</u><u>n</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>we</u><u> </u><u>get</u><u> </u><u>:</u>

→ x + y = 103

→ x + 68 = 103

→ x = 103 - 68

→ x = 35

  • <u>Hence</u><u>,</u><u> the school cafeteria sold </u><u>35</u><u> vegetable wraps.</u>

Answer:

35

Step-by-step explanation:

Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.

Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.

  • v + 3.40c = 266.20
  • v + c = 103

Subtract these equations.

  • 2.40c = 163.20

Divide both sides by 2.40.

  • c = 68

Substitute this value for c into the second equation.

  • v + (68) = 103

Subtract 68 from both sides.

  • v = 35  

The number of vegetarian wraps sold amounted to 35 in total.

Solve for x. 5(x – 10) = 30 – 15x
klio [65]
You can start by distributing the 5 to everything in the parenthesis.
5x-50=30-15x

Then get rid of your x values from one side, I chose to subtract 5x

-50 = 30 - 20x

Then subtract 30

-80=-20x
/-20
4=x

You can check by plugging your x into the equation to make sure it's right!

Billy left home at 9 a.M. And rode his bicycle to the park at an average speed of 10 miles per hour here I got the park at 9:30
tamaranim1 [39]

Answer:

Park is <u>5 miles</u> from Billy's home.

Step-by-step explanation:

Given:

Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.

Now, to find the distance from park to Billy,s home.

Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.

So, the time = (9.30 - 9.00) = 30 minutes

=\frac{30}{60}  =0.5\ hour.

Speed = 10 miles per hour.

Now, to get the distance from park to Billy's home we put formula:

Distance=Speed\times Time.

Distance=10\times 0.5

Distance=5\ miles.

Therefore, park is 5 miles from Billy's home.

Hi Help me with question 6b) pls
Romashka-Z-Leto [24]

Answer:

k = 9

Step-by-step explanation:

Consider the pattern on the right side , that is

T_{k} = k(k + 2) + 1 = k² + 2k + 1

Equating

k² + 2k + 1 = 100 ( subtract 100 from both sides )

k² + 2k - 99 = 0 ← in standard form

(k + 11)(k - 9) = 0 ← in factored form

Equate each factor to zero and solve for k

k + 11 = 0 ⇒ k = - 11

k - 9 = 0 ⇒ k = 9

But k > 0 , then k = 9
