4 0

The scenarios which matches the equation given are scenarios 3 and 4

Scenario 1 :

Let :

Cost of hamburger = x

Number of hamburgers = 1

Cost of Burritos = y

Number of burritos = 5

Amount spent on soda = $20

Total cost = $20

x + 5y + 2 = 20

Scenario 2 :

Price per shirt = x

2 shirts = x

A pair of shirt = x

5 pairs = 5x

Total Amount spent = $20

Additional amount spent = $2

x + 5x = $20 + $2

x + 5x = 22

Scenario 3 :

Amount spent per person = x

Amount spent on Sunday (2 persons) = 2x

Amout spent on Monday = number of plays × 2x = 5(2x)

Shoe rental = $2

Total Amout spent = $20

Equation : 2x + 5(2x) + 2 = 20

Scenario 4 :

Let :

Cost per diamond = x

Cost of 2 diamonds = 2x

Cost of gem = 5 times the cost of 2 diamonds = 5(2x)

Tax paid = $2

Total amount spent = $20

Equation : 2x + 5(2x) + 2 = 20

Hence, only scenario 3 and 4 matches the equation.

Ulleksa [173]

Answer:

1) Total length in inches = 162 inches

Step-by-step explanation:

express the total length of rope the three friends have in inches, feet, and yards.

2) Total length in Feet = 13.5 feet

3)Total length in yard = 4.5 yard

a) Total length in inches

Morgan has 42 inches of rope

Malcolm has 4 feet of rope

Convert to inches

1 foot = 12 inches

4 feet = 4 × 12 inches

= 48 inches

Roberto has 2 yards of rope

Convert to inches

1 yard = 36 inches

2 yards = 2 × 36 inches

= 72 inches

Hence, the total length of rope in inches

= (42 + 48 + 72)inches

= 162 inches

2) Total length in Feet

1 inch = 0.0833 feet

162 inches = 162 × 0.0833 feet

= 13.5 feet

2) Total length in yard

1 inch = 0.0278 yard

162 inches = 162 × 0.0278 yard

= 4.5 yard

. Find sets of parametric equations and symmetric equations of the line through the point parallel to the given vector or line (
omeli [17]

Answer:

a) L(x,y,z) = (-4,0,2)+(2,8,-7)*t

b) (2-z)/7= y/8=(x+4)/2 (option B)

Step-by-step explanation:

the parametric equation of the line passing through the point P₀= (-4,0,2) and parallel to the vector v=2i + 8j - 7k is

L(x,y,z)=P₀+v*t

therefore

L(x,y,z) = (-4,0,2)+(2,8,-7)*t

or

x=x₀+vx*t = -4 + 2*t

y=y₀+vy*t = 8*t

z=z₀+vz*t = 2 -7*t

solving for t in the 3 equations we get the symmetric equation of the line:

(2-z)/7= y/8=(x+4)/2

thus the option B is correct
