the sum of 3 consecutive integers is -69. Find the largest
x = the first integer
x + 1 = the second integer
x + 2 = the third integer.
Let's set each of our variables equal to -69
x + x + 1 + x + 2 = -69
Combine like terms
3x + 3 = -69
Subtract 3 from both sides.
3x = -72
Divide both sides by 3
x = -24
The first integer = x = -24
The second integer = x + 1 = -24 + 1 = -23
The third Integer = x + 2 = -24 + 2 = -22

A straight line is 180 degrees:
25x + 8 + 9x + 2 = 180
Combine like terms:
34x + 10 = 180
Subtract 10 from both sides:
34x = 170
Divide both sides by 34:
X = 5
Now solve the smaller angle:
9x + 2 = 9(5) + 2 = 45 + 2 = 47
They angle with the y is a vertical angle to 47 so needs to also equal 47:
7y + 5 = 47
Subtract 5 from both sides:
7y = 42
Divide both sides by 7:
Y = 6
Answer: x = 5, y = 6

The sum of the measures of a triangle is 180 degrees.a triangle has angle measures of 5x+2,6x and 134.find the measures of x
Answer:
4
Step-by-step explanation:
6x + 5x+2 + 134 = 180 All triangles have 3 angles = 180. Combine
11x + 136 = 180 Subtract 136
11x = 180 - 136
11x = 44 Divide by 11
x = 44/11
x = 4

Angles are
5x + 2 = 22
6x = 24
<3 = 134
Total = 180

Personal behavior is the only factor that determines if a person becomes ill.
The answer is False. Personal behavior is not the only factor that determines an individual’s illness or sickness. There are other factors which determine an individual’s sickness and dysfunction. There are reasons like obesity which leads to several diseases.
This is false because genetics and environmental factors may also come into play. So there are many factors to be considered if a person becomes ill.

12. Venu and Tanuj are running along a circular track. They take 48 seconds and 56 seconds to
complete a lap respectively. They begin from the starting point at the same time
6) How long does it take for them to meet at the starting point again?
How many laps will each boy have run by then?
Answer:
The meet at first time at starting point after 336 seconds,
Vanu have completed 7 laps while Tanuj has completed 6 laps.
Step-by-step explanation:
Given that Venu and Tanuj take 48 seconds and 56 seconds to
complete a lap respectively.
To meet them again at the startiong point, the time taken must be multiple of 56 and 48.
So, the minimum time required to meet them again at the startiong point is time taken for first time meet.
Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.
Number of laps by Venu
[tex]=\frac{336}{48}=7[/tex]
Number of laps by Tanuj
[tex]=\frac{336}{56}=6[/tex]
4. GROCERIES A local grocery store sells grapes for $1.99 per pound. Determine whether the function that models the
cost of grapes is discrete, continuous, or neither discrete nor continuous. Then state the domain and range of the
function.
Answer:
Ok, we know that the price, per pond of grapes, is $1.99.
Now the function that models the cost of grapes is:
C(x) = $1.99*x
Where x is the number of pounds that you buy.
Here we can assume two things:
1) The grapes are already in bags, so x can be only whole numbers, as x can take only whole numbers, the cost c(x) will be discrete because there are a lot of possible costs that are not accessible.
Then the domain is:
D: {0, 1, 2, 3, 4.....}
And the range is :
R: {0*$1.99. 1*$1.99, 2*$1.99, ...}
2)You can choose any amount of grapes that you want, and then the grapes are weighted when yo pay. (This has not really sense, but it is fun to analyze the problem in different ways)
Here the weight can take almost any value, because with individual grapes you can have almost any number of pounds.
But the unit that defines the total weight is the weight of a single grape.
Then if you have N grapes (and all of them weight almost the same, let's say M)
The total weight will e N*M
If you add one more grape, the weight is: (N + 1)*M
Then it is still discrete!
As we do not know the mean weight of a grape, we can not find the domain nor the range in this situation, so the one above is the one that we should consider the correct one.

Answer:
d
Step-by-step explanation:
If three distinct points lie in a plane, can also form a straight line. Therefore, option D is the correct answer.
Given that, if three distinct points lie in a plane, then the points can form a triangle.
We need to identify the counterexample for the conditional statement given.
What is a counterexample?A counterexample to a mathematical statement is an example that satisfies the statement's condition(s) but does not lead to the statement's conclusion. Identifying counterexamples is a way to show that a mathematical statement is false.
Now, if three distinct points lie in a plane, then the points always can not form a triangle.
If three distinct points lie in a plane, can also form a straight line.

77 is written as the product of two prime numbers 7 × 11. Can 702 be written as the product of two prime numbers? If not, why? What about 703?
Answer:
702 can't be written as the product of 2 prime numbers because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore, 702 is a prime number.
The prime factorization of 703 is 19 × 37. Since it has a total of 2 prime factors, 703 is a composite number.

Write 0.12 as a fraction.
Let x = ?
100x = ?
100x - x = ? - ?
99x = ?
X = ?
Answer:
Let 0.12 be x.
Here, x is recurring in two decimal places so we'll multiply it by 10-
10x = 1.22Now, by subtracting them-
[tex] \\ \implies \sf \: 10x - x = 1.22 - 0.12 \\ \\ \\ \implies \sf \: 9x = 1.1 \\ [/tex]
Now, we'll divide both sides by 9 to get x as a fraction -
[tex] \\ \implies \sf \: x = \frac{1.1}{9} \\ \\ \\ \star \: \large{ \boxed{ \sf{x = \frac{11}{90} }}} \\ [/tex]
