Answer:
3(2y + 5) = -21
open the bracket
6y + 15 = -21
collect like terms
6y = -21-15
6y = -36
divide by the coefficient of y
y = 36÷6
y= 6
Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 18, 10, 20, 18, 12, 19,12, 11 find the mean and median number of movies that the students saw
Answer:
I. Mean = 15
II. Median = 15
Step-by-step explanation:
Given the following data;
Total number of students = 8
x = 18, 10, 20, 18, 12, 19,12, 11
F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11
F(x) = 120
To find the mean;
Mean = F(x)/n
Mean = 120/8
Mean = 15
To find the median;
Median refers to the middle number of a sorted data.
x = 10, 11, 12, 12, 18, 18, 19, 20
Middle numbers = 12 and 18
Median = (12 + 18)/2
Median = 30/2
Median = 15
anyone think they could help me with this ???
Answer:
12°
Step-by-step explanation:
As we can see the triangles are congruent so
< F = < C ( being corresponding angles of congruent triangle)
< C = 29
Now
<A +<B + <C = 180° { being sum of angles of triangle }
5x + 1 + 90 + 29 = 180°
5x = 180° - 120°
5x = 60°
x = 12°

Factor the expression using the GCF 7+14
Answer:
We found the factors and prime factorization of 7 and 14. The biggest common factor number is the GCF number. So the greatest common factor 7 and 14 is 7.
Step-by-step explanation:
The value of the Expression 7+ 14 using the GCF is 21.
What is Greatest Common Factor?The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. The GCF of 18 and 24 is 2 * 3 = 6, which we multiply to obtain.
Given:
We have to add 7 + 14
Factorise the terms separately
7 = 7 x 1
14 = 7 x 2
So, the Greatest Common Factor is 7.
Thus, 7+ 14 = 7(1+ 2) = 7 x 3= 21

Of the numbers 5, 6, or 7, which is a solution of the inequality y + 4 < 10?
[tex] \begin{cases}5 \in y \\ 6 \in y \\ 7 \in y \end{cases}[/tex]
Solve the Inequality.[tex]y + 4 < 10 \\ y < 10 - 4 \\ y < 6[/tex]
Therefore, the value of y is lesser than 6. That meane it can't be y = 6 or greater. Hence, 5 is the solution to the Inequality.
Answery = 5 is the solution to the Inequality.

Answer:
r = 1Step-by-step explanation:
Use the slope formula:
m = (y₂ - y₁)/(x₂ - x₁)m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11Substitute values and solve for r:
-3 = (-11 - r)/(8 - 4)-3 = -(11 + r)/411 + r = 12r = 12 - 11r = 1Answer:

Answer: f(2)=1
Step-by-step explanation:
This is a function-related problem. In order to solve f(2), you need to substitute the value into the original function.
-----------------------------------------------------------------------------------------
f(x)=5x⁵-3x⁴- 17x³-4x²+10x+21
f(2)=5(2)⁵-3(2)⁴- 17(2)³-4(2)²+10(2)+21

r + 4s = -8
3r + 2s = 6
Answer:
R = 4
s = -3
Step-by-step explanation:
r + 4s = -8
3r + 2s = 6
there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:
-6r - 4s = -12 and added it to the first equation
+ 1r + 4s = -8
-5r = -20
r = 4
plug in to find 's': 4 + 4s = -8
4s = -12
s = -3

Answer: 6(u-2)+2=6u-10
Step-by-step explanation:
Then, any value of u makes the equation true.
The other side of this equation 6 (u-2) + 2 is 6u - 10 and is true for all values of u.
What is equation?An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.
Given:
6 (u-2) + 2
Simplify the above expression as shown below,
6 × u - 6 × 2 + 2 (Use distributive property)
6u - 12 + 2 (Add constant terms)
6u - 10

Answer:
100% is 9, 55% is 4.95, 75% is 6.75.
Step-by-step explanation:
Suppose that 100% were [tex]x[/tex]. Then 30% is 27, so [tex]0.3x=27[/tex] and we can divide both sides by 0.3 to see that [tex]x=\frac{27}{0.3}=\frac{27}{\frac{3}{10}} = \frac{27\cdot 10}{3} = 90.[/tex] So 55% is [tex]0.55x = 0.55 \cdot 9 = 4.95[/tex] and 75% is [tex]0.75x = 0.75\cdot 9=6.75[/tex]. (Note that we can divide the value of a percentage by 100 - the same as moving the comma by two places to the left - to get the decimal value.)
