1. What is the expanded form of the expression 3.6(t + 5)?


2. If you know the value of t, would the evaluated expression be different if you added the known value of t and 5 and then multiplied by 3.6? Explain.

Answers

Answer:

Step-by-step explanation:

1) The expanded form of 3.6(t + 5) is 3.6t + 18.

The expression 3.6(t + 5) is equivalent to 3.6t + 18 and yes, the given value will be different for different values of [t].

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the expression as -

3.6(t + 5)

We have the following expression -

3.6(t + 5)

3.6t + (3.6 x 5)

3.6t + 18

YES, the given value will be different for different values of [t].

Therefore, the expression 3.6(t + 5) is equivalent to 3.6t + 18 and yes, the given value will be different for different values of [t].

Given the equation y = 2 x - 8, what is the slope and the y -intercept?

Answers

Answer:

m=2 and b=-8

Step-by-step explanation:

This equation is organized in slope-intercept form, y=mx+b. In this form, m is the slope and b is the y-intercept.

When given the equation, y=2x-8, we can see that 2 is in the place of m and -8 is in the place of b. The reason the y-intercept isn't 8 is that y=2x-8 can be written as y=2x+(-8) since y=mx+b involves addition. Therefore, the slope is 2 and the y-intercept is -8.

m=2 and b=-8

**The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room are in the ratio 4 :3: 2. The combined area of these three rooms is 189 square feet. What is the area of each room?

Answers

Answer:4 : 3 : 2

x - area unit

area of the kitchen = 4x

area of the playroom = 3x

area of the dinning room = 2x

The combined area of these three rooms is 189 ft².

Therefore we have the equation

4x + 3x + 2x = 189

9x = 189    |:9

x = 21 ft²

area of the kitchen = 4x = 4(21) = 84 ft²

area of the playroom = 3x = 3(21) = 63 ft²

area of the dinning room = 2x = 2(21) = 42 ft²

Step-by-step explanation:

Answer:4 : 3 : 2

x - area unit

area of the kitchen = 4x

area of the playroom = 3x

 

area of the dinning room = 2x

 

The combined area of these three rooms is 189 ft².

Therefore we have the equation

4x + 3x + 2x = 189

9x = 189    |:9

x = 21 ft²

area of the kitchen = 4x = 4(21) = 84 ft²

area of the playroom = 3x = 3(21) = 63 ft²

area of the dinning room = 2x = 2(21) = 42 ft²
