Answer:
arithmatic sequence
common difference
5
Step-by-step explanation:
This increases by 5 each time which means that it's an arithmatic sequence
because it's arithmatic that means that we have a common difference. To find it just take the second number and subtract it by the first (5)

4. THE LOV TEMPERATURES FOR A VEEK IN EDMONTON, ALBERTA ARE -15°C, -1200
-10°C, -12°C, -18°C, -20°C, AND_-25°C. WHAT IS THE MEAN LOV
TEMPERATURE FOR THE WEEK? SHOW YOUR WORK
Answer:
-16°C
Step-by-step explanation:
The lov temperatures for a week are :
-15°C, -12 , -10°C, -12°C, -18°C, -20°C, and -25°C.
We need to find the mean love temperature for the week.
Total no. of observations = 7
Mean = sum of observations/total no of observations
[tex]M=-\dfrac{15+12+10+12+18+20+25}{7}\\\\M=-16^{\circ} C[/tex]
So, the mean temperature is -16°C.
The junior class sold 120 turkey dinner plates and 200 chicken dinner plates for a total of $2,150. The senior class sold 100 turkey plates and 300 chicken plates, raising $2,625. What was the cost of each turkey dinner plate? What is the cost of each chicken plate?
Answer:
Write the system of equations with 2 unknowns x and y denoting the prices of two types of chickens:
(1) 120x + 200y = 2150
(2) 100x + 300y = 2625
Solving the system of equations above we have 2 solutions:
x = 15/2 = $ 7.5 and y = 25/4 = $ 6.25

Divide using any method 2x^2+5x+1 ÷ X+3
Question:
Solve the equation 2x2−5x+3=0 by the method of completing square.
Answer:
We have,
2x2−5x+3=0
⇒x2−25x+23=0 (Dividing throughough by 2)
⇒x2−25x=−23 (Shifting the constant term on RHS)
⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)
⇒(x−45)2=1625−23⇒(x−45)2=16
Augie has hit the baseball 75% of the time this year. How many times will he hit the ball if
he bats a total of 32 times?
I’m need some help please! :(
Answer:
24 times
Step-by-step explanation:
75% = 0.75, so then you just do 0.75 * 32 = 24
Answer:
For this question, multiply 75% or 0.75 with 32. The result would be 24. So, Augie has hit the baseball 24 times.

How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?
Answer:
The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.
Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.
Step-by-step explanation:
First let's find the area:
5x² × 12x
= 60x³
Now the perimeter:
2(5x² + 12x)
= 10x² + 24x
Solve the system of equations using elimination. How many solutions does the system have?
15j + 12k = 18
5j + 4k = 6
Responses
A. One solution, j = 3, k = 3
B. No solution
C. One solution, j = 10, k = 8
D. Infinitely many solutions
Answer:
I hope it helps u
Step-by-step explanation:
Let's solve your system by elimination.
15j+12k=18;5j+4k=6
Multiply the second equation by -3, then add the equations together.
(15j+12k=18)
−3(5j+4k=6)
Becomes:
15j+12k=18
−15j−12k=−18
Add these equations to eliminate j:
0=0
Answer:
Infinitely many solutions

What is parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
Given:
ABCD is a parallelogram.
And BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6.
The two diagonals bisect each other.
AC = AE + EC
AC = 2AE
AC = 8x-12
The diagonals of a parallelogram are equal.
So,
BD = AC
5x+3 = 8x-12
x = 3
So, AC = 12
Therefore, the AC is 12 unit.

In rectangle FGHJ , the diagonals intersect at point M, FM = 3.2x , and JG = 40.
What is the value of x?
Enter your answer as a decimal in the box.
Answer:
[tex]x=6.25[/tex]
Step-by-step explanation:
FM=3.2x
JG=40
