The sum of 7 consecutive odd integers is 217. What is the smallest of the integers?
Answer:
25
Step-by-step explanation:
n+(n+2)+(n+4)+(n+6)+(n+8)+(n+10)+(n+12)=217
7n+42=217
7n=175
n=25
25+27+29+31+33+35+37=217
Answer:
25
Step-by-step explanation:
Let the smallest odd integer be n.
The integers are: n, n + 2, n + 4, n + 6, n + 8, n + 10, n + 12
Their sum is 217.
n + n + 2 + n + 4 + n + 6 + n + 8 + n + 10 + n + 12 = 217
7n + 42 = 217
7n = 175
n = 25

x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
1/2x+1/3 x=10
Hey there!☺
[tex]Answer:\boxed{x=12}[/tex]
[tex]Explanation:[/tex]
[tex]\frac{1}{2}x+\frac{1}{3}x=10[/tex]
1/2x + 1/3x = 10 Simplify both sides
(1/2x + 1/3x) = 10 Combine like terms
5/6 x = 10
(6/5) * (5/6x) = (6/5) * (10) Multiply both sides by 6/5.
x = 12

Do this for at least three different values of n. What is the relationship between the lengths of the sides of and ? Explain the relationship in terms of n.
Answer:
n=3.5 a=1.41 units a'=4.95 units b3 units b'10.5 units c2.24 units c'=7.83 units
Step-by-step explanation:
This answer assumes that n = 3.5. The ratio of each side length on to the corresponding side length on is equal to 3.5. For example, a′ = 3.5a. The ratio is equal to the scale factor, n.
What is the solution for x in 12x - 4 = 5x + 24?
Answer:
x=4
Step-by-step explanation:
Add 4 to both sides.
12x=5x+24+4
Simplify 5x+24+4 to 5x+28
Subtract 5x from both sides
12x-5x=28
Simplify 12x-5x1 to 7x
7x=28
Divide both sides by 7
28/7
simplify 28/7
x=4
Answer:
4
Step-by-step explanation:
12x - 4 = 5x + 24 convert like terms to the same side of equation
12x - 5x = 24 + 4 as you can see, when we send a terms to the other side of equation its sign changes
7x = 28 multiply both sides by 7
x = 4

Answer:
The Answer would be OD) Dividing both sides of Equation A by-3 gives x + 7 = -8.
Step-by-step explanation:
Simplify by dividing both sides by negative 3 so -3(x+7)/-3 would be x+7 and 24/-3 would be -8,
Thus, OD) is the answer.
The statement that explains this is true would be OD) Dividing both sides of Equation A by-3 gives x + 7 = -8.
It is given that Mai says x is a number that makes Equation A true and also a number that makes Equation B true.
• Equation A: -3 (x + 7) = 24
• Equation B: x + 7 = -8
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Simplify the Equation A by dividing both sides by negative 3;
so -3(x+7)/-3 would be;
x+7 = 24/-3
Then x + 7 = -8
x= -8 + 7
x = -1
Therefore, The statement that explains this is true would be OD) Dividing both sides of Equation A by-3 gives x + 7 = -8.

scores on the act college entrance exam follow a bell-shaped distribution with mean 18 and standard deviation 6. Wayne's standardized score on the ACT was -0.5. what was Wayne's actual ACT score?
Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15

A) −10
B) −4
C) 4
D) 10
Answer:
x = 10
Step-by-step explanation:
[tex]3 - \frac{3}{4}x = \frac{1}{4}x - 7[/tex]
Start by subtracting 3 to both sides
[tex]-\frac{3}{4}x = \frac{1}{4}x-10[/tex]
Subtract 1/4x from both sides ( -3/4 - 1/4 ) = - 1
[tex]-x = -10[/tex]
Divide both sides by a negativ 1 to get rid of the negative
∴ [tex]x = 10[/tex]

A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk in 3/4 hours if he walks twice as fast?
PLS HELP ASAP
Answer: 9 miles
Step-by-step explanation:
The distance would be 9 because if the speed walker walked 4.5 miles in 3/4 of an hour, he would be going 6 mph (miles per hour).
If he walks twice as fast, he would be going 12 mph.
If he walks for 3/4 of an hour (45 minutes) at 12 mph, he would walk 9 miles.
9 miles he walks in 3/4 hours if he walks twice as fast.
What is speed?Speed is characterized as the pace of progress of the position of an item toward any path. Speed is estimated as the balance of length to the time in which the distance was covered. Speed is a scalar amount as it has just course and no size.
4 1/2 miles will be covered by him in 3/4 hour
if the speed walker covered 4.5 miles in just over an hour
The duration would indeed be 9 since the speed walker might be moving at a rate of six miles per hour.
He would be moving at 12 miles per hour if he walked twice as quickly.
He would cover 9 miles in 3/4 of an hour (45 minutes) of walking at a speed of 12 miles per hour.
