Given:
Given the sum 619+59
Required: Another expression using commutative property and the simplified expression
Explanation:
The commutative property says that for any two real numbers,
[tex]a+b=b+a[/tex]So, the expression 619+59 can also be written as 59+619, using commutative property.
Now, find the sum.
So, the sum is 678.
Final Answer: Another expression of 619+59 is 59+619 and its sum is 678.

Answers
Natural numbers are the non-negative integers
So we will put inside its circle all the positive integers and zero
Let us find them using the 1st picture
there are 0 and square root 36 because its value is 6
Whole numbers are positive numbers only
So we can put 0 in a natural circle and 6 in the whole part and 12/4 because it equals 3
Integers are positive and negative whole numbers
We have -8 and - square root 25 because it equals -5
So put -8 and - square root 25 in the integer circle
Rational numbers are all numbers can but in the form of the fraction
So we will choose the number with decimal or fraction
6.2, -1/2, 2.21 on the rational part
The rest of the numbers are irrational numbers
Put them in the part of irrational numbers

The amount of garbage, G produced by a city with population p is given by G = f ( p ) . G is measured in tons per week, and p is measured in thousands of people. The town of Tola has a population of 45,000 and produces 6 tons of garbage each week. Express this information in terms of the function f. f = 6 / 45 f ( 45 ) = 6 f ( 6 ) = 45
Answers
Solution:
Given that the amount of garbage G produced by a city with population p is expressed as
[tex]\begin{gathered} G=f(p) \\ where \\ G\text{ is measured in tons per week} \\ p\text{ is measured in thousands of people} \end{gathered}[/tex]If a town Tola has a population of 45,000 and produces 6 tons of garbage per week, this implies that we substitute these parameters into the above equation.
This gives
[tex]6=f(45)[/tex]Hence, in terms of function f, the information is expressed as
[tex]f(45)=6[/tex]The second option is the correct answer.
If a car travels at a speed of 45 mi/h fort hours, then travels 65 mi/h for m hours, what does theexpression 45t +65m represent?The expression represents the (select)
Answers
total distance travelled by the car (option D)
Explanation:
When speed = 45mi/h
time = t hours
when speed = 65mi/h
time = m hours
45t +65m means 45mi/h × t + 65mi/h × m
The formula that relates the speed and the time is distance:
speed = distance/time
distance = speed × time
The distance for the first speed and time = 45mi/h × t hours = 45t
The distance for the second speed and time = 65mi/h × m hours = 65m
The sum of the two distance = distance covered by the car = 45t + 65m
Hence, we can say the expression 45t +65m represents the total distance travelled by the car (option D)

50% of 90 is 45

a. 20% of 60 is 12 because 60x20/100 = 60x0.2 = 12
b. 25% of 24 is 6 because 6x100/25 = 24
c. 14% of 100 is 14 because 100x(14/100) = 14
d. 50% of 90 is 45 is 14 because 90x50/100 = 45
e. 10% of 70 is 7 because 7x100/10 = 70

The population of people in a town increases by 100 each year. Which equation represents the situation? Let p represent the amount the population has increased and t represent the number of years.t = 100 + pp = 100 + tt = 100pp = 100t
Answers
From the problem, the population increases by 100 each year.
a constant increase of 100 means that the slope of a line is 100.
Slope is the same as constant increase or rate of increase.
The equation of the line with a slope is :
[tex]y=mx+b[/tex]where m is the slope and b is the initital population.
Since we dont have an initital population, b = 0.
The equation will be :
[tex]y=100x[/tex]It is stated also that P represents the population that has increased. So y will be p.
and t represent the number of years. So x will be t.
That will be :
[tex]p=100t[/tex]ANSWER :
The equation is p = 100t

find the equation of line with points (3, 3) that passes through a slope of 2/3
Answers
hello
the standard equation of a straight line is given as y = mx + b
y = y-coordinate
x = x-coordinate
m = slope
b = intercept
the points given are (3, 3) and the slope = 2 / 3
y = mx + b
y = 3
x = 3
let's substitute in our values and solve for b
[tex]\begin{gathered} y=mx+b \\ 3=\frac{2}{3}(3)+b \\ 3=2+b \\ b=3-2 \\ b=1 \end{gathered}[/tex]since we have the value of the slope, we can simply write the equation from y = mx + b to y = 2/3x + 1
[tex]y=\frac{2}{3}x+1[/tex]this is the equation of the line.
but we can further simplify this by looking for the LCM of the denominators of the independent variables
[tex]\begin{gathered} y=\frac{2}{3}x+1 \\ y=\frac{2x+3}{3} \\ \text{cross multiply both sides} \\ 3y=2x+3 \end{gathered}[/tex]the equation can be rewritten as 3y = 2x + 3

Use graphs to find the set.(−2,4) ∪ [−1,6]Im not for sure on how to solve the set?
Answers
Answer:
A. The set is {-1, 0, 1, 2, 3, 4, 5, 6}
Explanation:
Note the following;
*When we use parentheses or open brackets, ( ), in an interval notation, it signifies that those points are excluded in the set.
*When we use closed or square brackets, [ ], in an interval notation, it signifies that those points are inclusive in the set.
*The union symbol (U) is used to join two intervals together.
Given the interval notation, (−2,4) ∪ [−1,6], since there -2 and 4 are in parentheses, it means that they are not included in the set while -1 and 6 are included in the set since they are in square brackets. So the members of the set can be represented in a graph as;
