Solve for y: 5(x+y)=20+3x

consider the distance equation d=rt, where d is the distance (in feet), r is the rate (in feet per second), and t is the time (i

Answer:

yes, they are proportional

Step-by-step explanation:

A proportion is a relation that can be modeled by a straight line through the origin. The equation will have the form ...

y = kx

where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.

__

If you start with the equation relating distance, rate, and time:

d = rt

and you fix the time at 50 seconds, then the equation becomes ...

d = 50t

This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.

Can you help me I dont understand 6. Solve: 143 = 13y

Charra [1.4K]

Answer:

y=11

Step-by-step explanation:

To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.

To Check your answer:

Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.

T.L Hanna High School’s theatre department is putting on their annual play. Tickets (t) are $12 each. Parking is $5 flat. You an

GalinKa [24]

Answer:

No. of ticket bought is 4

Step-by-step explanation:

Let the no. of ticket bought be x

Given cost of 1 ticket = $12

Therefore cost x ticket = x*cost of 1 ticket = x*$12 = $12x

parking fee = $5

given that it is flat so, whatever be the no. of ticket bought or family member,

the parking cost will remain $5 only.

Total money paid by family = parking charge + cost x ticket = 5+12x

But , given that family paid total of $53

then

5 + 12x = 53

=> 12x = 53-5 = 48

=> x = 48/12 = 4

Thus, no. of ticket bought is 4.

This can be validated as shown below

cost of 4 ticket as 12 each will be = 12*4 = 48

thus total money paid = $(48+5 )= $53

41 is what percent of 205

gulaghasi [49]

Answer:

41 is the 20% of 205.

Step-by-step explanation:

Given the information, the question is what percentage of 205 is 41.

In this case, 205 is the one hundred percent and we need to determine the exact percentage of 41 in relation to 205.

Percentage = (41 * 100)/205

Percentage = 4,100/205

Percentage = 20%

41 is the 20% of 205.
