If x represents a number, then write an expression for a number that is three more than the number.

Answers

Answer: $x+3$

Step-by-step explanation: Since x is a quantity that we are unsure about, in order to represent it as an expression where we are adding 3 more to it, you would write it as $x+3$ .

The freezing point of water is 0 C. Scientists use positive numbers to show temperatures above the freezing point water and negative numbers to show temperatures below the freezing point of water.The freezing point of maple syrup is 18 C. What does -18'C represent in this situation

Answers

Answer:

The -18°C temperature as the freezing point of maple syrup means that the temperature at which maple syrup changes from liquid to solid (that is, freezes) is 18° below the freezing point of water.

Step-by-step explanation:

It is explained that the freezing point of water is used as the standard or reference point to calibrate the Celsius scale.

The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.

So, a temperature/freezing point of -18°C simply means that the temperature/freezing point is 18° lower than the freezing point of water.

Because of flu epidemic, 36 students are absent. If this is 1/6 of the school's population, what is its total population?A) 6
B) 42
C) 186
D) 216

Answers

The total population is 216. so option D is correct.

What is the unitary method?

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

Here, 36 is only 1/6 of the population,

then, 36 x 6 = 216

6/6 or one whole of the population which is 216.

Hence, option D is correct.

Solve by substitution
y=x+3
y=2x+5

Answers

y = x+3
y = 2x+5
x+3 = 2x+5
x+8 = 2x
x = 8

I think I did that right, anyway.

y=x+3
y=2x+5

1. Solve for the variable that is easiest to find.
In this case I will solve for x.
y=x+3
-3 -3
y-3=x

2. Now plug in (y-3) for x in the other equation.
y=2(y-3)+5 ~use distributive property
y=2y-6+5 ~combine like terms
y=2y-1
-2y=-2y
-y=-1 ~multiply both sides by -1
y=1

3. Since you have a value for y you can plug it in to solve for x.
y=x+3
1=x+3
-3 -3
-2=x

Answers:
y=1
x=-2

What is the value of 3 to the power 2 over 3 to the power 4? A. 1 over 81 B. 1 over 27 C. 1 over 9 D. 1 over 3

Answers

Answer:

Option C is correct.

Step-by-step explanation:

Given Expression:

$(3^2)/(3^4)$

We need to find Value of given expression.

Consider,

$(3^2)/(3^4)$

$\implies3^(2-4)$

$\implies3^(-2)$

$\implies(1)/(9)$

Therefore, Option C is correct.

One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do $3^((2-4))$ since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get $3^(-2)$ , which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.
