Answer:
[tex]\huge\boxed{\sf{6x+15}}[/tex]
Step-by-step explanation:
Hello.
Let's solve this problem.
First, multiply 2 times 3x:
6x
Now, add 7 plus 8:
15
Write the expression:
6x+15
Can this expression be simplified any further?
No.
Why?
Because variables and constants are not like terms.
In this case, the variable is x, and the constant is 15.

Patrick makes about 74% of his free throws when playing basketball. He shoots 40 free throws at practice. About how many free throws will he make?
Pls help this is due today
Answer:
about 30
Step-by-step explanation:
Convert 74% to a decimal by dividing by 100 or by moving the decimal two places left.
74.% = 0.74
Multiply
0.74 x 40 = 29.6
Round to the nearest whole number

Explain how to find the axis of symmetry
Answer:
THE AXIS OF SYMMETRY IS ALWAYS THE X VALUE OF THE VERTEX
Step-by-step explanation:
The vertex is where the graph performs the u shape bend.
The vertex is always -b/2a. so in problem one, it would be 6/2(3) which is 1. That is the x value so the axis of symmetry would be x=1.
Solve the inequality for x. 1/2 x − 2 > 22
A) x > 12
B) x > 48
C) x > −12
D) x > −48
B is correct
1/2x-2>22
Remember 1/2=0.5
We write the equation as
0.5x-2 >22
Collect like terms
0.5x > 22+2
0.5x>24
Divide through by 0.5
X>24/0.5
X>48
Option b
Answer:
B x > 48
Step-by-step explanation:
1/2x -2 >22
Mulitply both sides of the inequality by 2
x - 4 > 44
Move the constant to the right
x > 44+4
Add the numbers
x>48

Consider x2 10x _____. How many unit tiles need to be added to complete the square and form a perfect square trinomial expression? unit tiles.
The number of unit tiles need to be added to complete the square and form a perfect square trinomial expression is 25.
What is algebra tile?Algebra tiles used to represent the algebraic expression in the table form. The shape of algebra tile is square and rectangle, in which the variables represented.
A trinomial which is expressed as the square of the binomial equation is a perfect square trinomial.
Let the missing number for the given expression is g. Therefore,
[tex]x^2 +10x+g[/tex]
Now, to make the above expression the perfect square trinomial expression, this has to be make such that it can be written in the squared form.
To find the value of g, half the middle term and square it. As the value of the middle term is 10. Thus, the value of the g is,
[tex]g=\left(\dfrac{10}{2}\right)^2\\g=5^2\\g=25[/tex]
Put this value in the above expression as,
[tex]x^2 +10x+25\\(x+5)^2[/tex]
Hence, the number of unit tiles need to be added to complete the square and form a perfect square trinomial expression is 25.

Answer: The 2nd choice.
Step-by-step explanation:
The y-intercept is the y coordinate when x = 0. Based on the table, we can see that the y coordinate is 12 when x is 0.
The slope is equal to (y2-y1)/(x2-x1) for any given points (x1,y1) and (x2,y2).
We can choose the point (0,12) to represent (x1,y1) and the point (6,0) to represent (x2,y2).
Therefore, the slope is (0-12)/(6-0) = -12/6 = -2

12. In a Fibonacci sequence, every term (except the first two) is the sum of the two

Find the sixteenth term of a Fibonacci sequence whose first two terms are -3 and 9.
13. If you buy 31 floops, the total cost will be less than 40$. But if you buy 32 floops, the total cost will be more than 41$. Assuming these prices do not involve tax, what is the cost of one floop?
12. If the first two terms of the sequence are -3 and 9, the next few terms are
-3 + 9 = 6
9 + 6 = 15
6 + 15 = 21
15 + 21 = 36
and so on. Continuing in this way, you'd find the 16th term to be 4359.
13. Let x be the cost of 1 floop.
31 floops cost less than $40, so 31x < 40 or x < 40/31.
32 floops cost more than $41, so 32x > 41 or x > 41/32.
Equivalently,
41/32 < x < 40/31
and
41/32 ≈ 1.28125
40/31 ≈ 1.29032
which means x = $1.29.

I really need answers
Answer:
x = 50°
y = 50°
z = 80°
Step-by-step explanation:
working out x:
angles on a straight line add up to 180°
x + 130° = 180°
subtract 130 on both sides
x = 180° - 130°
x = 50°
working out y:
two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°
y = 50°
working out z:
the sum of a triangle add up to 180°
add up the angles of x and y and equate to 180°
50 + 50 + z = 180
100 + z = 180
subtract 100 on both sides
z = 180 - 100
z = 80°

Answer:
first you find the common denominator, it is 6.
so the numbers would stay the same. now that our denominators are the same we shall add.
1+2 = 3
3/6.
You can simplify by thinking what multiplication table is 3 and 6 in? its 3 so simplify
3/6 divide both by 3
you get 1/2 so your final answer shall be 1/2

What is the circumference of the circle? Answer in terms of pi
Answer:
10π
Step-by-step explanation:
The circumference of a circle is the distance of the outside of the circle. The formula for circumference is C=2πr.
In the question, you are given the diameter. Diameter is the radius times 2. So, to find the radius you can divide the diameter by 2. Since, 10cm/2 is 5 cm, 5cm is the radius.
Then, plug this information into the formula to solve for C.
2*5π = 10πThis means that, in terms of pi, the circumference is 10π cm.
