6
Step-by-step explanation:
31-5=26

Answer:
[tex]\boxed{\textsf{ The first negative term of the sequence is \textbf{-4} .}}[/tex]
Step-by-step explanation:
A sequence is given to us . And we need to find the first negative term of the sequence. So the given sequence to us is :-
[tex]\sf\implies Sequence = 31 , 26 , 21 , 16 ..... [/tex]
Here first term of the sequence is 31. And the common difference is 26 - 31 = -5 . Hence here (-5) is added to each number to obtain the second number of the sequence .
Here the last term mentioned is 16. And we are subsequently adding (-5) to each term to obtain the next term . Next third term will be obtained after adding 5×(-3) = -15 .
And that term will be , 16 - 15 = 1 .
Hence the last positive term is 1 . The next term term after adding (-5) will be the first negative term.
[tex]\sf \implies 1st \ negative \ term = 1 -5 =\pink{-4} . [/tex]

Answer:
x = 38
y = 41
z = 123
Step-by-step explanation:
x + y + z = =202
y = x + 3
z = 3y = 3(x + 3) = 3x + 9
x + y + z = x + x + 3 + 3x + 9 = 5x + 12 = 202
5x + 12 = 202
5x = 190
x = 38
y = x + 3 = 41
z = 3y = 123

Which of the following is the product of (3x − 5) and (3x + 5)?
A. 9x2 − 25
B. 9x2 − 30x − 25
C. 9x − 10
D. 9x2 + 25
Answer:
Step-by-step explanation:
These binomials make up the difference of squares.
3x * 3x = 9x^2
3x * 5 = 15x
-5 * 3x = - 15x
-5 * 5 = - 25
Notice the 2nd and 3rd terms. They are equal except that one is plus and the other minus. That means they cancel. You are left with
9x^2 - 25

Brainiest answer to whoever is correct
Answer:
39 degrees
Step-by-step explanation:
Vertical angles are opposite angles made by two intersecting lines, this means they share a vertex. Vertical angles are always congruent. Congruent angles have the same measurements, so the other angle must be 39 degrees.

You have at most $75 to spend on books and music. You want to spend less than $20 on music and no more than $60 on books. Which system represents the situation?
Answer:
$20>$75>$60
Step-by-step explanation:
hope it helps
The system of inequalities that represent the situation are -
x < 20
y ≤ 60
x + y ≤ 75
We have $75 to spend on books and music and we want to spend less than $20 on music and no more than $60 on books.
We have to determine which system represents the situation.
You have $50 to spend on chocolates and toffees. You want to spend more than $20 on toffees and less than $15 on chocolates. How will you find the possible solutions under such constraints ?Assume the cost spend on toffees is $x and that on chocolates is $y. Then-
x > 20
y < 15
x + y ≤ 50
Solve them graphically and you will find the possible solution set.
According to the question, we have -
Amount available to spend = $75
For music → amount < $20
For books → amount ≤ 60
Assume the cost spend on music is $x and that on books is $y.
Then -
x < 20
y ≤ 60
x + y ≤ 75
Check the graph attached for solution region. The points inside the triangle formed (marked by red thick boundary) represents the points which satisfy the above conditions.

Calculate the area of this triangle.
17 cm
8 cm
15 cm-
Area - Triangles
Overview
Answer:
There are 3 possible answers because you didn't state which value was base or height.
Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*8)
A = 1/2(120)
A = 60
Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)
A = 1/2(b*h)
A = 1/2(17*8)
A = 1/2(136)
A = 68
Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*17)
A = 1/2(255)
A = 127.5
Marina has a bag of lemon watermelon and strawberry candies she is going to choose one candy from the bag the probability of choosing strawberry candy is 1/5 there are 16 lemon candies and eight watermelon candies in the bag how many strawberry candies are in the bag
Answer:
There are 6 strawberry candies in the bag
Step-by-step explanation:
The probability of an event occurring = (The number of required outcome) ÷ (The number of possible outcome)
The given parameters in the question are;
The number of different types of fruit in Marina's bag = 3
The type of fruits in the bag = Lemon, watermelon, strawberry
The probability of choosing strawberry, P = 1/5
The number of lemon candies in the bag = 16
The number of watermelon candies in the bag = 8
Let, 'x', represent the number of strawberry candies in the bag
Therefore, by the definition of probability, we have;
P = 1/5 = x/(x + 16 + 8)
x + 16 + 8 = 5·x
16 + 8 = 5·x - x = 4·x
24 = 4·x
∴ x = 24/4 = 6
The number of strawberry candies in the bag, x = 6 strawberry candies.
One stick is 9cm longer than the other 2/5 of the longer stick is equal to 1/2 of the shorter stick. Find the length of the longer stick
Answer:
Length of the longer stick = 45 cm
Step-by-step explanation:
Let the length of shorter stick be x cm
Therefore, length of longer stick = (x + 9) cm
According to the given information:
[tex] \frac{2}{5} (x + 9) = \frac{1}{2} x \\ \\ 2 \times \frac{2}{5} (x + 9) = x \\ \\ 4(x + 9) = 5x \\ \\ 4x + 36 = 5x \\ \\ 36 = 5x - 4x \\ \\ 36 = x \\ \\ x + 9 = 36 + 9 = 45 \\ [/tex]
Length of the longer stick = 45 cm
