The sum of two consecutive numbers is 157. This equation, where n is the first number, represents the situation:2n + 1 = 157.

What is the first number?

Answers

Answer:

Step-by-step explanation:

2n + 1 = 157

2n = 157 - 1

2n = 156

n = 156/2

n = 78

Answer:

the answer is B.78

Step-by-step explanation:

2n + 1 = 157

2n = 157 - 1

2n = 156

n = 156/2

n = 78

A point on the line y=3x-4 has an x- coordinate of 50. what is the y-coordinate of this point

Answers

The y-coordinate of the point is 146
In order to calculate y-coordinate, just substitute the value of x-coordinate into the expression:
y = 3x - 4
y = 3(50) - 4
y = 150 - 4
y = 146

In short, Your Answer would be 146

A flower shop sells tulips and roses. The price of each tulip is the same, and the price of each rose is the same. One customer bought 7 tulips and 9 roses for $25.90. Another customer bought 4 tulips and 8 roses for $19.80. How much will it cost a customer to buy 5 tulips and 6 roses?

Answers

You can use system of linear equations to find the solution.

The  cost to customer to buy 5 tulips and 6 roses will be $17.75

Given that:

  • The price of all tulips are same.
  • The price of all roses are same.
  • Price of 7 tulips and 9 roses is $25.90
  • Price of 4 tulips and 8 roses is $19.80

To find:

Cost of buying 5 tulips and 6 roses.

Naming the prices:

  • Let price of one tulip be $x
  • Let price of one rose be $y

Forming system of equations:

By given data, we have:

7 tulip + 9 roses costs $25.90

or

7x + 9y = 25.9

And

4 tulips + 8 roses costs $19.8

or

4x + 8y = 19.8

Thus, we have two equations.

Using method of substitution:

From equation first, we have:

7x + 9y = 25.9\n\nx = (25.9-9y)/(7)

Substituting this value in second equation, we get:

4((25.9 - 9y)/(7)) + 8y = 19.8\n\n103.6 - 36y + 56y = 138.6\n20y = 138.6 - 103.6\n\ny = (35)/(20) = 1.75\n

Thus, we have:

x = (25.9-9y)/(7) \n\nx = (25.9 - 15.75)/(7) = 1.45

Thus, the price of a tulip = x = $1.45

and the price of a rose = y = $1.75

Now, calculating price of 5 tulips and 6 roses:

\: \rm Total \: Cost = 5x + 6y = 5 * 1.45 + 6 * 1.75 = \$17.75

Thus, the cost to a customer who buys 5 tulips and 6 roses would be $17.75

It will cost a customer $17.75 to buy 5 tulips and 6 roses.

Step-by-step explanation:

Let,

Cost of one tulip = x

Cost of one rose = y

According to given statement;

7x+9y=25.90       Eqn 1

4x+8y=19.80       Eqn 2

Multiplying Eqn 1 by 4

4(7x+9y=25.90)\n28x+36y=103.60\ \ \ Eqn\ 3

Multiplying Eqn 2 by 7

7(4x+8y=19.80)\n28x+56y=138.60\ \ \ Eqn\ 4\n

Subtracting Eqn 3 from Eqn 4

(28x+56y)-(28x+36y)=138.60-103.60\n28x+56y-28x-36y=35\n20y=35

Dividing both sides by 20

(20y)/(20)=(35)/(20)\ny=1.75

Putting y=1.75 in Eqn 1

7x+9(1.75)=25.90\n7x+15.75=25.90\n7x=25.90-15.75\n7x=10.15

Dividing both sides by 7

(7x)/(7)=(10.15)/(7)\nx=1.45

Cost of 5 tulips and 6 roses = 5x+6y = 5(1.45)+6(1.75) = 7.25+10.50 = $17.75

It will cost a customer $17.75 to buy 5 tulips and 6 roses.
