A set of 4 consecutive odd integers has a sum of 216. What are the integers?
Answers
Answer:
Hope this helps!!
Step-by-step explanation:
So the four consecutive odd integers are: 51 , 53 , 55 and 57 .
If the first integer is n, then the other three are n+2,n+4 and n+6
and we have:
216=n+(n+2)+(n+4)+(n+6)=4n+12
Subtract 12 from both ends and transpose to get:
4n=204
Divide both sides by 4
to get:
n=51
So the four consecutive odd integers are:
51,53, 55 and 57.

Let's solve your equation step-by-step.
7x+3+x+55=14x−5+x
Step 1: Simplify both sides of the equation.
7x+3+x+55=14x−5+x
7x+3+x+55=14x+−5+x
(7x+x)+(3+55)=(14x+x)+(−5)(Combine Like Terms)
8x+58=15x+−5
8x+58=15x−5
Step 2: Subtract 15x from both sides.
8x+58−15x=15x−5−15x
−7x+58=−5
Step 3: Subtract 58 from both sides.
−7x+58−58=−5−58
−7x=−63
Step 4: Divide both sides by -7.

What do the differences between the points (as shown on the graph) represent? On a coordinate plane, point B is at (2, 7) and point D is at (4, 14). StartFraction 7 over 2 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 2 over 7 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1. StartFraction 2 over 7 EndFraction can be used to find the unit rate if one divides 2 by 7 and compares the result to 1.
Answers
Answer:
StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
B(2, 7) and D(4, 14)
substitute the values
The unit rate is
therefore
StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

What is the volume of material he must purchase?
2 ft3
4 ft3
6 ft3
8 ft3
Answers
Answer:
In this problem, we use the formula for volume which is:
volume=(length*width*height)/3
Since the base of the triangle is a square, we simply know that the length and width is equal.
L = W = 2 ft
H = 6 ft
Solution:
V = (2*2*6)/3V = 8 ft^3
The correct answer is 8 ft^3

Question 2 An exponential model y = a.6 passes through the points (0,9) and (3,243). What are the values of a and b?
Answers
Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a [tex]b^{x}[/tex]
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 )
a = 9
y = 9 [tex]b^{x}[/tex]
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b = [tex]\sqrt[3]{27}[/tex] = 3
y = 9[tex](3)^{x}[/tex] ← exponential equation
