Answer:

V=1

Step-by-step explanation:

6 - 4v = 3 - v

move the varible

6 - 4v + v = 3

collect like terms

-3v = 3 - 6

divide both sides by -3

V = 1

Answer: = 1

Step-by-step explanation: 6−4v=3−v

Step 1: Simplify both sides of the equation.

6−4v=3−v

6+−4v=3+−v

−4v+6=−v+3

Step 2: Add v to both sides.

−4v+6+v=−v+3+v

−3v+6=3

Step 3: Subtract 6 from both sides.

−3v+6−6=3−6

−3v=−3

Step 4: Divide both sides by -3.

−3v

−3

=

−3

−3

v=1

Answer:

v=1

Find the coordinates of a point on the directed segment from (-3,6) to (7,1) that divides it into a ratio of 3:1.
Masja [62]

Step-by-step explanation:

To divide a directed segment, we need to divide the length of the segment, along the x and the y directions separately.  Then add the subdivided segment to the starting point of the directed segment (-3,6) to get the point of division.

Let the length be denoted by delta, then

delta = (7,1) - (-3,6) = (10,-5)

Multiply delta by the ratio of 3 / (3+1) = 3/4

(10,-5) * 3/4 = (7.5, -3.75)

Add the subdivided segment to the starting point:

(-3,6) + (7.5, -3.75) = (4.5, 2.25)

So the point of division is (4.5, 2.25)

A dietitian at a hospital wants a patient to have a meal that has 109 grams of protein, 76
Alex787 [66]

The number of variables and the number of unknowns are equal, therefore, the system can be solved by simultaneous equation

The required number of servings are;

  • Number of servings of salmon steak is <u>1.5 servings</u>
  • Number of servings of baked eggs is <u>3 servings</u>
  • Number of servings of acorn squash is <u>1 serving</u>

Reason:

Given parameter;

Required mass of protein = 109 gram

Required mass of carbohydrate = 76 grams

Required mass of vitamins = 93.5 mg

The dinner = Salmon steak, baked eggs, and acorn squash

Mass of protein in a salmon steak serving = 40 grams

Nutrition value of salmon steak;

Protein = 40 grams

Carbohydrate = 30 grams

Vitamin A. = 1 milligram

Nutrition value of baked eggs;

Protein = 15 grams

Carbohydrate = 2 grams

Vitamin A. = 20 milligrams

Nutrition value of acorn squash;

Protein = 4 grams

Carbohydrate = 25 grams

Vitamin A. = 32 milligrams

Let <em>A</em> represent the amount of serving of salmon steak, let <em>B</em> represent the

number of serving of baked eggs, and let <em>C</em> represent the number of

servings of acorn squash, we have;

40·A + 15·B + 4·C = 109

30·A + 2·B + 25·C = 76

A + 20·B + 32·C = 93.5

Solving the above simultaneous equation with a graphing calculator gives;

A = 1.5, B = 3, C = 1

Therefore, the dietician should provide <u>1.5</u> serving of salmon stake, <u>3</u>

servings of baked eggs, and <u>1</u> serving of acorn squash
