Twice the sum of a number x and 9 is equal to 12 less than the number x. What is the value of x?
Answer:
x = -30
Step-by-step explanation:
Let x be the number.
2(x + 9) = x - 12
Use distributive property of multiplication
2x + 18 = x - 12
Simplify by combining like terms
2x - x = -12 - 18
x = -30
Hector is building a metal sculpture in the shape of an equilateral triangle. After he divides a metal bar into 3 equal pieces, Hector figures each side of the triangular sculpture can be at most 9 feet long.
Answer:
27
Step-by-step explanation:
because 3*9=27 so that it
The inequality equation is 3L ≤ 27 or L ≤ 9 feet , where L is the length
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Let the length of the equilateral triangle be L
And , each of the lengths of the triangle is at most 9 feet long means that each of the lengths is less than or equal to 9 feet
So , L ≤ 9 feet
And , the perimeter of an equilateral triangle is the addition of the three equal lengths
So , 3L ≤ 27 feet
Therefore , the value of A is 3L ≤ 27 feet
Hence , the inequality equation is 3L ≤ 27 feet

The mean absolute deviation for the number of hours students practiced the violin is 6.4.
What is the mean absolute deviation?
The average absolute deviation of the collected data set is the average of absolute deviations from a center point of the data set.
Given
Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours.
The given data set is;
45, 38, 52, 58, 42
Mean Deviation = Σ|x − μ|/N.
μ = mean, and N = total number of values
|x − μ| = |45 − 47| = 2
|38− 47| = 9
|52− 47| = 5
|58− 47| = 11
|42− 47| = 5
The mean absolute deviation for the number of hours students practiced the violin is;
[tex]\rm Mean =\dfrac{2+9+5+11+5}{5}\\\\Mean=\dfrac{32}{5}\\\\Mean = 6.4[/tex]
Hence, the mean absolute deviation for the number of hours students practiced the violin is 6.4.

what is the equation of the line that passes through the point (-4,2) and has a slope of -5/4
Answer:
The answer is
[tex] \huge y = - \frac{5}{4} x - 3[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-4,2) and slope of -5/4
We have
[tex]y - 2 = - \frac{5}{4} (x + 4) \\ y - 2 = - \frac{5}{4} x - 5 \\ y = - \frac{5}{4} x - 5 + 2[/tex]
We have the final answer as
[tex]y = - \frac{5}{4} x - 3 \\ [/tex]

Answer:
John's ball hit the court first
Step-by-step explanation:
to solve for who hit the court first we have to look for when x was 0
John's ball hit the court in 1 second
now to look for the other guy we substitute 0 to the equation
0 = (-16t - 2) (t - 2)
we cannot substitute 0 to t because its looking for when it hit the court. x is 0 because it hits the ground
soo i guess we distribute ?
or actually we equate both to 0 i think
-16t - 2 = 0 t - 2 = 0
-16t = 2. t = 2
t = 2/-16
t = 1/-8 t = 2
theres two answers but 1/-8 is wrong because theres no such thing as the ball going underground (LOL) so his ball hit the court two seconds later
John's ball hit the court first i think
im not sure how to do the rest, but i do know how to do the first. Sorry but hope this helps you a little!

A. 23 points
B. 13 points
C. −1 1/3 points

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
The value of a stock increases 14 2/3 points twice in one week.
and, The other three days the value decreases by 10 points, 8 1/3 points, and 12 2/3 points.
So, the point in that week
= 2 x 14 2/3 - 10 - 8 1/3 - 12 2/3
= 2 x 44/3 - 10 - 25/3 - 38/3
= 88/3 - 10 - 63/3
