Answer:
x = -9
Step-by-step explanation:
2x + 8( x + 3 ) = 3( x - 13 )
Dstribute;
2x + 8 ( x + 3 ) = 3 ( x - 13 )
2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))
2x + 8x + 24 = 3x - 39
Combine like terms;
2x + 8x + 24 = 3x - 39
10x + 24 = 3x - 39
Inverse operations;
10x + 24 = 3x - 39
-3x -3x
7x + 24 = -39
-24 -24
7x = - 63
/7 /7
x = -9

Mrs. Hector wanted to bring giant souvenir snow globes, which weigh 1.5 kg each, back to the USA as presents for her students. Mrs. Hector's suitcase weighs 2.4 kg, but she wanted to fill it with as many snow globes as possible. Write and solve an inequality to determine the maximum number of snow globes that Mrs. Hector could have brought back in her suitcase.
Answer:
the maximum number of snow balls can bought back = 1.6
Step-by-step explanation:
Let
Mrs. Hector brings total number of giant snow globes = x
As given,
weight of 1 snow globe = 1.5 kg
So,
Weight of x snow globe = 1.5x
As given,
She have to take them in a suitcase of weight 2.4 kg
∴
For number of snow globes we have the equation,
1.5x = 2.4
⇒x = [tex]\frac{2.4}{1.5}[/tex] = 1.6
So, the maximum number of snow balls can bought back = 1.6

find the value of the variables. x and y
Answer:
x = 29.4
y = 17
Step-by-step explanation:
sin 90° / 34 = sin 60° / x
x = 34·sin 60°
x = 29.4
sin 90° / 34 = sin 30° / y
y = 34·sin 30°
y = 17
a ladder is leaning against a building. the top of the ladder is 21 feet up the wall. the bottom of the ladder is 20 feet away from the base of the building. how long is the ladder
Answer:
29
Step-by-step explanation:
We can use the pythagorean theorem to find the length of the ladder
[tex] {20}^{2} + {21}^{2} = c {}^{2} [/tex]
[tex]400 + 441 = {c}^{2} [/tex]
[tex]841 = {c}^{2} [/tex]
[tex]c = 29[/tex]
The answer is 29
Answer:
19 ft .
Step-by-step explanation:
Given :-
Height = 21 ft .Base = 20ft.Using Pythagoras Theorem :-
p² + b² = h² 20² + 21² = h²400 + 441 = h²h² = 841h = √841 h = ± 19 ft h = 19 ft .A large field measures 70 feet by 525 feet. If you divide it up into equal square garden plots, what size would the largest possible plot be with sides of whole number length?
9514 1404 393
Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35
__
I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD
what is the rule for solving any equation?
A. just look at it and it will be solved
B. always add the numbers
C. Do the inverse or opposite operations
D. the is no rule for solving equations
Answer:
C) Do the inverse or opposite operations
Step-by-step explanation:
Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.
An object moves around x + y = 25 (which represents a
circle whose radius is 5 meters) at a constant speed. At time
t = 0 seconds, the object is at (5,0). When t = 1, it is at (4,3). Where is the object when t = 2? When t = 3? when t = n?
What is the object’s speed? At what times does the object return to (5, 0)? To arrive at your answers, what assumptions did you make?
Answer:
Step-by-step explanation:
There is an error in the question.
x + y = 25 is NOT the equation of a circle.
It should be x^2 + y^2 = 5^2.
Parametric equations for the circle:
x = 5cosθ
y = 5sinθ
After 1 second, the object is at (4,3), so θ=arctan(3/4).
At 2 seconds, θ=2arctan(3/4). The object is at (5cosθ,5sinθ) = (1.4, 4.8).
At 3 seconds, θ=3arctan(3/4). The object is at (-1.76, 4.68).
360°/arctan(3/4) ≈ 9.764
The object returns to (5,0) after 9.764 seconds.

Answer:
z is 95 degrees.
Step-by-step explanation:
Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.

A tree grows 2 inches per year. It was 14 inches tall when it was planted. what would be this function discrete continuous or neither? whould it be a linear an exponential or neither? what would be the domain?
please help greatly appreciated
Answer:
This function is a continuous linear function that's domain is all positive real numbers.
Step-by-step explanation:
This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.
It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.
The domain is all positive real numbers since time/years can not be negative.
the options are:

Answer:
P is greater than -8

When the circle is hollow that means its never equal to
When the circle is full it means its equal to
it matters which direction the line is going
if it goes to the right and it is hollow that it is greater than
if goes to the left and it is hollow it is less than the number the circle is on
If the circle is full when it goes to the right then that means its greater than or equal to from the number its going from
same thing to the left

What is the answer hurry!!!
Answer:
D. 9 + 4√5
Step-by-step explanation:
What we're essentially doing here is squaring 2 + √5. (2 + √5 and 2 + 1√5 are essentially the same)
(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)
Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5
4 + 2√5 + 2√5 + (√5)²
Step 2: Combine 2√5 and 2√5 to get 4√5.
4 + 4√5 + (√5)²
Step 3: The square of √5 is 5.
4 + 4√5 + 5
Step 4: Add 4 and 5 to get 9.
9 + 4√5 is the final answer to this question.

. Which of the following is a zero of the polynomial f(x)= x5+2x4+x+2?
A. I
B.-1
C.-2
D. 2
Answer:
x = -2 is a function
Step-by-step explanation:
To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1
we have this as:
Let us try the value x = -2
-2^5 + 2(-2)^4 - 2 + 2
= -32 + 32 - 2 + 2 = 0
This means that the term x = -2 is a root of the equation
