Jill is making lemonade. the original concentraton was 25 ml of concentrate to 2 l of water people found that too strong so she decreased the concentration to 20 ml of concentrate to 2 l of water by percentage did she decrease the concentrate

Answer:

You need to find equation of line containing (1,-3) and (7,15)

First find slope (m) = 15+3)/7-1 = 18/6 = 3

So, eq of line is y +3 = 3( x-1)

y+3 = 3x -3

y-3x +6 = 0

m∠A = 118 degrees (Angle ∠A is 118 degrees when you substitute x = 35 into the expression (3x + 13)).

In this problem, we are given three angles of a triangle: ∠A, ∠B, and ∠C, expressed in terms of the variable x. We need to find the measure of angle ∠A.

1. Start with the given information:

  - ∠A = (3x + 13) degrees

  - ∠B = (x - 8) degrees

  - ∠C = x degrees

2. We know that the sum of the angles in any triangle is always 180 degrees. So, we can write an equation based on this fact:

  ∠A + ∠B + ∠C = 180

3. Substitute the expressions for each angle:

  (3x + 13) + (x - 8) + x = 180

4. Now, simplify and solve for x:

  3x + 13 + x - 8 + x = 180

  Combine like terms:

  5x + 5 = 180

  Subtract 5 from both sides to isolate 5x:

  5x = 180 - 5

  5x = 175

  Divide by 5 to find the value of x:

  x = 35

5. Now that we've found the value of x, we can find the measure of ∠A by substituting x back into the expression for ∠A:

  ∠A = (3x + 13)

  ∠A = (3 * 35 + 13)

  ∠A = 105 + 13

  ∠A = 118 degrees

So, the measure of angle ∠A is 118 degrees.

The fraction of the ham sandwich will be 4.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Robert slices a large loaf of bread to make 12 sandwiches. He made 3 turkey sandwiches and 5 veggie sandwiches. The portion of the ham sandwich will be calculated as below:-

Total sandwich = Turkish sandwich  +  veggie sandwiches + ham

12 = 5 + 3 + ham

ham = 12 - 8 = 4

Therefore, the fraction of the ham sandwich will be 4.
