Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
Answer:x=1/4
Step-by-step explanation:
120x + 21 = -9
120x = -9 -21
120=-30
x=-1/4

In a triangle, the measures of the three angles are x, x + 12 , and x-9. What is the measure of each angle?
Answer:
x+(x+12)+(x-9)=180
3x+12-9=180
3x=180-3
3x=177
x=177/3
x=59
Each angle is 59°, 71° and 500°

Suman bought a tea pack of 0.345kg. From that, 40g of tea was taken. What
is the amount of tea left with her?Pls answer fast
Answer:
The remaining tea = 0.305 kg
Step-by-step explanation:
The mass of Tea pack = 0.345 kg
The mass of tea taken = 40 g
as
40 g = 0.04 kgTherefore, all we need is to subtract 0.04 kg from 0.345 kg to determine the tea left:
i.e.
Remaining Tea left = Total tea - Tea taken
= 0.345 - 0.04
= 0.305 kg
Therefore, the remaining tea = 0.305 kg

Answer:
f(-1) = 3, f(3) = 3
Step-by-step explanation:
This question requires that you choose which of the two equations to uses given the value of x. -1 < 1 so you choose equation f(x) = -x + 2 for f(-1). 3 > 1 so you choose f(x) = x² - 4x + 6 for f(3)
ABC has A(-3,6),B(2,1),and C(9,5) as its vertices the length of side AB is units . The length of side BC is ?units . The length of side AC is ? Units .ABC ?
Answer:
The length of side AB is [tex]\sqrt{50}[/tex] units.
The length of side BC is [tex]\sqrt{65}[/tex] units.
The length of side AC is [tex]\sqrt{145}[/tex] units.
Step-by-step explanation:
To find the length of each side, we use the formula for the distance between two points.
Distance between two points:
Points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Side AB:
Points [tex]A(-3,6),B(2,1)[/tex]. So the distance between them is:
[tex]D = \sqrt{(2-(-3))^2 + (1-6)^2} = \sqrt{50}[/tex]
The length of side AB is [tex]\sqrt{50}[/tex] units.
Side BC:
Points [tex]C(9,5),B(2,1)[/tex]. So the distance between them is:
[tex]D = \sqrt{(2-9)^2 + (1-5)^2} = \sqrt{65}[/tex]
The length of side BC is [tex]\sqrt{65}[/tex] units.
Side AC:
Points [tex]A(-3,6),C(9,5)[/tex]. So the distance between them is:
[tex]D = \sqrt{(9-(-3))^2 + (5-6)^2} = \sqrt{145}[/tex]
The length of side AC is [tex]\sqrt{145}[/tex] units.
On what interval(s) of x is f(x) increasing?
On what interval(s) of x is f(x) decreasing?
Answer:
Increasing → (-∞, -0.5)
Decreasing → (-0.5, ∞)
Step-by-step explanation:
From the picture attached,
Vertex of the parabola represents the highest point of the curve of a quadratic function 'f'.
Left part from the vertex is increasing and the right side is increasing.
x-coordinates of the vertex,
x = -0.5
Therefore, graph of the function is increasing in the interval (-∞, -0.5)
And decreasing in the interval (-0.5, ∞).

Aiden plant grew 75 inches in 100 weeks. At this rate, how much would it grow in 30 weeks
Answer:
22.5 inches
Step-by-step explanation:
To find the unit rate, you divide the amount the plant grew by the amount of weeks. We learned that the plant grew 75 inches in 100 weeks, so we divide 75/100, to get 0.75. This means that the plant grows 0.75 inches per week, so in 30 weeks, it would grow 22.5 inches. This is calculated by multiplying 0.75 by 30 weeks.

Answer: 12 = x + 4
Step-by-step explanation:
We know that the length of the green line is 12.
And the length of the black line will be equal to the sum of the lengths of the two smaller segments, x, and 4
Then the length of the black line is x + 4
We want to write an equation that says that the length of the green line is equal to the length of the black line, this is:
Length of green line = Length of black line
12 = x + 4
That is the equation we wanted.
Now we could solve it if we subtract 4 in both sides of the equation:
12 - 4 = (x + 4) - 4
8 = x

1. List the properties of a parallelogram
2. Is it possible for a trapezoid to be a parallelogram? Why or why not?
2a. Could a rhombus be a square? Why or why not?
9514 1404 393
Answer:
see the list belownoyesStep-by-step explanation:
1. The dictionary definition of a parallelogram is ...
a quadrilateral with opposite sides parallel
As a consequence of this condition, a number of additional properties arise:
opposite sides are the same lengthopposite angles are congruentadjacent angles are supplementarydiagonals bisect each other__
2. The dictionary definition of a trapezoid (US; trapezium, UK) is ...
a quadrilateral with one pair of parallel sides.
As a consequence of this condition, it is not possible for a trapezoid to be a parallelogram.
__
3. A rhombus is a special case of parallelogram in which all sides are the same length. A square is a special case of rhombus in which all angles are congruent (as are the diagonals). Yes, a rhombus may be a square.
[tex]\displaystyle 2b.[/tex] A rhombus can never be a square because although opposite interiour angles and all four sides are congruent, their interiour angles are not right angles.
[tex]\displaystyle 2a.[/tex] A trapezium is impossibly a parallelogram because a parallelogram has two pairs of parallel sides.
[tex]\displaystyle 1.[/tex] Convex polygon with two pairs of opposite sides that are parallel and congruent [equal in length (see above picture)]

Owen and his children went into a restaurant where they sell hotdogs for $4 each and tacos for $2.50 each. Owen has $60 to spend and
buy a minimum of 18 hotdogs and tacos altogether. If x represents the number of hotdogs purchased and y represents the number of tac
purchased,
Answer:
Hotdogs is 10
and Tacos 8 in numbers purchased
Step-by-step explanation:
Step one:
given data
Le x represents the number of hotdogs purchased
and y represents the number of tac
hotdogs = $4 each
and tacos = $2.50 each
The total amount at hand = $60
Step two:
The systems of the equations for the situation is given as
4x+2.5y= 60---------1
x+y=18-----------------2
Required
The number of Hotdogs and Tacos purchased
from 2
x= 18-y
put x= 18-y in eqn 1
4(18-y)+2.5y= 60
72-4y +2.5y=60
collect like terms
-4y+2.5y=60-72
-1.5y= -12
divide both sides by -1.5
y= -12/-1.5
y= 8
put y= 8 in eqn 2
x+8=18
x= 18-8
x= 10
The smallest bone in the human body is the stapes (or stirrup) in the inner ear, at about 3 mm. The largest bone is the femur, which is about 480 mm in length in an average male. About how many times smaller is the stapes than the femur in the human body?
Answer:
160
Step-by-step explanation:
It's simple you have to do 480 divided by 3 and you will get 160. To check if you multiply 3x160 it would equal 480. So 160 times larger. Hope this helps!
I am a 2-digit number. if you double a number and multiply it by 3, it results to 72. what am I?

Step-by-step explanation:
2x (3) = 72 so 6x = 72 and so x = 12
Answer:12
Step-by-step explanation:
You divide 72 by 3 then that answer by 2 then you get 12. Then if you do 12•2 =24 Then 24 •3 it equals 72

Find the gradient of the line segment between the points (7,2) and (10,-5).
Give your answer in its simplest form.
Given:
Two end points of a line segment are (7,2) and (10,-5).
To find:
The gradient of the given line segment.
Solution:
We know that, gradient of a line segment is the slope of that line segment.
The end points of the line segment are (7,2) and (10,-5), so slope or gradient of the line segment is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-5-2}{10-7}[/tex]
[tex]m=\dfrac{-7}{3}[/tex]
Therefore, the gradient of the given line segment is [tex]\dfrac{-7}{3}[/tex].

Step-by-step explanation:
from 1954 to 1955 the sales decreased by 80 percent. If the sales in 1956 were the same as the sales in 1954, what was the increased from 1955 to 1956
9514 1404 393
Answer:
400%
Step-by-step explanation:
Suppose sales in 1954 were 500. Then 80% of that amount is 400. A drop of 400 puts sales in 1955 at 500 -400 = 100.
The increase back to 500 in 1956 is an increase of 400 from a base of 100. As a percentage increase, that is ...
400/100 × 100% = 400% . . . . increase from 1955 to 1956
