Thomas earns 15 mowing lawns over 3 days. How much money would he earn in 4 days if he earned the same amount every day
Answer: 20 Dollars
Step-by-step explanation:
15 divided by 3 is 5. So, then multiply 4x5 and that equals 20
Answer:
$20
Step-by-step explanation:
$15 for mowing lawns for 3 days
15 / 3 = 5
He charges $5 for each lawn he mows.
5 * 4 = 20
So for 4 days he would earn $20 from mowing the lawns

Use elimination to solve the system of equations.
5x + 13y = 20
– 5x – 3y = 30
Answer:
y = 5
x = -9
Step-by-step explanation:
5x + 13y = 20
-5x - 3y = 30
5x - 5x = 0
13y - 3y = 10y
20 + 30 = 50
10y = 50
y = 5
~~~~~~~~~~~~~~
5x + 13(5) = 20
-5x - 3(5) = 30
5x + 65 = 20
-5x - 15 = 30
5x = -45
-5x = 45
x = -9

Let f(x) = 5x – 3 and g(x) = 2x². Perform the function operation and then find the domain of the result.
(f+g)(x)
(f+g)(x) = (Simplify your answer.)
Answer:
(f+g)x= 2x²+5x-3
The domain x∈ Real number.
Step-by-step explanation:
Given that f(x) = 5x - 3 and g(x) = 2x²
(f+g)x = f(x) + g(x)
So, by using the given function
(f+g)x= (5x-3) + (2x²)= 2x²+5x-3
As the result, 2x²+5x-3, is a polynomial, so domain of the result is all the real numbers.
You get in an elevator and ride down 5 floors. You realize you forgot something, so you stay on the elevator and ride back up 5 floors. Which expression represents the number of floors you are from your original position?
answers -5+5
Answer:
(0 - 5) + 5
Step-by-step explanation:
Picture the initial floor you were on in the beginning as ground level or "zero." you go down five floors- so youre going below zero, which would be a negative. However, because you are going back up those five floors, you are back on ground level. Thus, the answer would be zero.
what is the equation of the line that is perpendicular to 3x -6y =2 and contains the point (-2,--5)
Answer:
y=-2x-12
Step-by-step explanation:
first, putt 3x-6y=2 in standard form:
subtract 3x from both sides: -6y=-3x+2
divide both sides by -6 to isolate y: y=1/2x-1/3
if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2
now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)
y+2=-2(x+5)
Use the distributive property: y+2=-2x-10
subtract 2 for both sides to isolate y: y=-2x-12

For the system shown below, what is the value of z? 3x - y = 16 3x - 4z = 2 y = -2x +14
5
6

2
Answer:
c) 4
The value of z= 4
Step-by-step explanation:
Step(i):-
Given equations are
3x - y =16 .. . (i)
3x -4z =2 .. . (ii)
2x +y = 14 .. .(iii)
solving (i) and (ii) equations , we get
Adding (i) and (ii)
3 x -y + 2x +y = 16 +14
5 x = 30
x = 6
step(ii):-
Substitute 'x' =6 in equation (i), we get
3(6) -y =16
18 - 16 =y
y = 2
x =6 and y =2
substitute x=6 in equation (ii) , we get
3 (6) - 4 z = 2
18 - 2 = 4 z
16 = 4 z
z = 4
Final answer:-
x = 6 , y = 2 and z =4
The value of x from the given equation is 19
System of equationsGiven the system of equation expressed as;
3x - y = 16 3x - 4z = 2 y = -2x +14Substitute equation 3 into 1
3x - (-2x+114) = 16
3x + 2x - 114 = 16
5x = 130
x = 26
Since 3x - 4z =2
3(26) - 4z = 2
78 - 4z= 2
4z = 76
z=19
Hence the value of x from the given equation is 19

Eduardo takes a sheet of paper and cuts from one corner to the opposite corner, making two triangles. If the piece of paper is 45 centimeters long and 60 centimeters wide, how long is the diagonal cut that Eduardo made?
Given:
Length of sheet of paper = 45 centimeters
width of the sheet of paper = 60 centimeters
To find:
The length of the diagonal cut that Eduardo made.
Solution:
We know that, a sheet of paper is a rectangle.
Diagonal of a rectangle is
[tex]Diagonal=\sqrt{length^2+width^2}[/tex]
Putting length = 45 and width = 60, we get
[tex]Diagonal=\sqrt{(45)^2+(60)^2}[/tex]
[tex]Diagonal=\sqrt{2025+3600}[/tex]
[tex]Diagonal=\sqrt{5625}[/tex]
[tex]Diagonal=75[/tex]
Therefore, the length of the diagonal cut that Eduardo made is 75 centimeters.

Skye needs $17,150 for each year of college. She will receive $4300 in scholarships and grants each year, and she will earn $2100 each year through a work study program. Including her financial aid, what is Skye's estimated cost per year?
Answer:
$10750
Step-by-step explanation:
Given data
Total amount Skye needs= $17,150
We are told that each year She will receive $4300 in scholarships
and She will earn $2100 each year
Each year She will get= 4300+2100= $6400
Hence the deficit is = 17150-6400= $10750
Therefore the estimate cost she will have to pay per year is $10750

The sum of 3 consecutive multiples of 4 is 120. Find the numbers.
Answer:
The required numbers are: 36, 40, 44
Step-by-step explanation:
Let first number = 4x
Second number = 4(x+1)
Third number = 4(x+2)
There sum = 120
We need to find the numbers
We can write:
[tex]4x+4(x+1)+4(x+2)=120\\4x+4x+4+4x+8=120\\12x+12=120\\12x=120-12\\12x=108\\x=\frac{108}{12}\\x=9[/tex]
So, we get x = 9
Now, finding the numbers:
first number = 4x = 4(9) =36
Second number = 4(x+1) = 4(9+1) = 4(10) = 40
Third number = 4(x+2) = 4(9+2) = 4(11) = 44
So, The required numbers are: 36, 40, 44

Answer: y= (4/3)x + 5/3
Step-by-step explanation:
Write in Slope-Intercept Form
−3y + 5 = −4x
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Subtract 5 from both sides of the equation.
−3y = −4x − 5
Divide each term by −3 and simplify.
−3y/−3 = −4x/-3 + −5/-3
Cancel the common factor of −3 and divide y by 1
y= −4x/-3 + −5/−3
Dividing two negative values results in a positive value.
y= (4)x/3 + −5/-3
y= (4/3)x + 5/3

Given:
The equation of line p is
[tex]y=-\dfrac{1}{3}x-3[/tex]
Line p and q are parallel.
To find:
The equation of line q.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
The equation of line p is
[tex]y=-\dfrac{1}{3}x-3[/tex]
The slope of the line is [tex]-\dfrac{1}{3}[/tex].
We know that the slopes of parallel lines are equal.
Line p and q are parallel. So,
Slope of line q = [tex]-\dfrac{1}{3}[/tex]
Line q passes through (6,-4) with slope [tex]-\dfrac{1}{3}[/tex], so the equation of the line is
[tex](y-y_1)=m(x-x_1)[/tex]
Where, m is the slope.
[tex](y-(-4))=-\dfrac{1}{3}(x-6)[/tex]
[tex]y+4=-\dfrac{1}{3}x+2[/tex]
[tex]y=-\dfrac{1}{3}x+2-4[/tex]
[tex]y=-\dfrac{1}{3}x-2[/tex]
Therefore, the equation of line q is [tex]y=-\dfrac{1}{3}x-2[/tex].

What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:
a, a + d, a + 2d, ... , a + (n+1)d, ...
Its nth term is
[tex](n-1)dT_n = a + (n-1)d[/tex]
(for all positive integer values of n)
And thus, the common difference is
[tex]T_nT_{n+1} - T_n[/tex]
for all positive integer values of n
We are given that;
Sequence= C C G T A C
Now,
DNA replication is the process by which DNA is copied in cells123. During DNA replication, each strand of the original DNA molecule serves as a template for the synthesis of a new, complementary strand. The new strand is made by adding nucleotides that are complementary to the template strand, following the base pairing rules: A pairs with T, and C pairs with G.
This is the complementary sequence that follows the base pairing rules.
Therefore, by the given sequence answer will be G G C A T G.
