The sum of two numbers is 19, and their difference is 55. What are the two numbers?

Answers

Answer 1

Answer:

37 and -18

Step-by-step explanation:

Let one number be x and other y

1 x + 1 y = 19 .............1

1 x -1 y = 55 .............2

Eliminate y

multiply (1)by 1

Multiply (2) by 1

1 x 1 y = 19

1 x + -1 y = 55

Add the two equations

2 x = 74

/ 2

x = 37

plug value of x in (1)

1 x + 1 y = 19

37 + 1 y = 19

1 y = 19 -37

1 y = -18

y = -18

37 and -18

Function R gives the amount of rain measured by a rain gauge hours since it started raining. The amount of rain is measured in millimeters.

What does each expression or equation represent in this situation

a. R(3)

b. R(0.5)=14

Answers

Answer:

R(3) means that it has rained 3 millimeter and R(0.5)=14 means in 14 hours it has rained half a millimeter.

Step-by-step explanation:

The function R defines the amount of rain for a certain number of hours.

R(3) means the amount of rain in 3 hoursR(0.5) = 14 means the amount of rain in 0.5 hours is 14 millimeters

This function R can be represented as:

[tex]\mathbf{y = R(x)}[/tex]

Where:

y represents the amount of rain, and x represents the time

So, the meaning of R(3) is:

The amount of rain in 3 hours

While the meaning of R(0.5) = 14 is:

The amount of rain in 0.5 hours is 14 millimeters

Trisha’s parents bought a new house that has 2,255 square feet.
The price per square foot was $98. How much did they pay for the house? Enter your answer in the box.

Answers

Answer:$220,290

Step-by-step explanation:

2,255 multiplied by 98 is 220,290

The total cost of Trisha’s parents new house is $220990.

Given that, Trisha’s parents bought a new house that has 2,255 square feet.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The price per square foot was $98.

So, the total cost of house = Number of square feet × The price per square foot

= 2,255 × 98

= $220990

Therefore, the total cost of Trisha’s parents new house is $220990.
