Answer:
-3 > x
Step-by-step explanation:
Multiply 2x and 1 by 9. You have 18x + 9 < 9x - 18.Add 18 to 9. You are adding because it is the opposite of subtraction, so it cancels out. You now have 18x + 27 < 9x.Subtract 18x from 9. There is no addition sign in front of the 18x, but it's basically implied. You now have 27 < -9x.Divide both sides by -9. When you divide by a negative, the inequality sign flips. You now have -3 > x.

Manuel se ha gastado 2/8 partes de la paga en ropa y 1/12 parte en dulces. ¿Qué fracción de la paga le queda?, ¿Si le dieron 45€ de paga, cuanto ha gastado y cuanto le queda?.
Responder:
2/3; 30 €
Explicación paso a paso:
Fracción gastada en ropa = 2/8
Fracción gastada en dulces = 1/12
Fracción restante:
1 - (Fracción gastada en ropa + fracción gastada en dulces)
1 - (2/8 + 1/12)
L. C. M de 8 y 12 = 24
1 - (6 + 2) / 24
1 - 8/24
1 - 1/3
= (3 - 1) / 3
= 2/3
Si la paga era de 45;
Cantidad restante: 2/3 de 45
= 90/3
= 30 €
Andrew spent $45.45 on two shirts that were the same price and a pair of pants. If the pants were $16.99, how much was each shirt?
Answer:
22.72
Step-by-step explanation:
45.45 divided by 2 is 22.725
Answer:
$14.23
Step-by-step explanation:
$45.45 - $16.99 ( pants ) = $28.46
$28.46 / 2 (since 2 shirts)
$14.23 for both shirts!

Can someone give me the reason why 2 is congruent to 11
Answer:
alternate int. <s of parallel lines
Step-by-step explanation:
We are told that lines r and s are parallel.
Lines r and s are curt by transversal line m.
Theorem:
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
Angles 2 and 11 are alternate interior angle, so they are congruent.
Answer: alternate int. <s of parallel lines

John uses 1 2 3 cups of milk to make a sauce recipe, and then uses 2 1 4 cups of milk to make a cake recipe. How much milk did he use in total to make the two recipes?
Answer:
3.91
Step-by-step explanation:
It is given that,
John uses [tex]1\dfrac{2}{3}[/tex] cups of milk to make a sauce recipe, and then uses [tex]2\dfrac{1}{4}[/tex] cups of milk to make a cake recipe.
We need to find how much milk did he use in total to make the two recipes. It can be calculated by simply adding [tex]1\dfrac{2}{3}[/tex] cups of milk and [tex]2\dfrac{1}{4}[/tex] cups of milk. So,
[tex]T=1\dfrac{2}{3}+2\dfrac{1}{4}\\\\=\dfrac{5}{3}+\dfrac{9}{4}\\\\=3.91[/tex]
So, she will need 3.91 units of milk to make the two recipes.
Convert 15°C to Fahrenheit. Use the formula F = C + 32
A. 33°F
B. 27°F
C. 85°F
D. 59°F
Using the equation given, F = 15 + 32 which equals 47, so I don't see how any of the choices are accurate, but if I had used the proper equation, I would get 59 Farenheit or answer D!

help with math hw please
Answer:
C
Step-by-step explanation:
This is called the hinge theorem, where you find out if an angle is small or big. first, you draw a triangle out and label it. when you finish this you can go and find the smallest side. The angle across from the side will be the smallest. In this problem, the smallest is <H, but that answer is not on there. So you can go and find the largest side and then the angle across from it will be the biggest, which is <G. Since the only thing, the question is asking for is "which statement is true", you can put C because <G is the biggest.
The state of Colorado covers about 1.04 x 10^5 square miles. The Indian Ocean covers about 2.808 x 10^7 square miles. How many times bigger is the Indian Ocean than Colorado?
Answer:
27976000
Step-by-step explanation:
1.04 x 10^5=104000, and 2.808 x 10^7=28080000
28080000-104000=27976000

Use always, sometimes or never to make a true statement:
Intersecting lines are _____________ coplanar.
Two planes _____________ intersect in exactly one point.
Three points are _____________ coplanar.
A plane containing two points of a line _____________ contains the entire line.
Four points are _____________ coplanar.
Two lines _____________ meet in more than one point.
Two skew lines are __________ coplanar.
Line TQ and Line QT and are _________ the same line.
Answer:
1. Intersecting lines are always coplanar
2. Two planes never intersect in exactly one point
3. Three points are always coplanar
4. A plane containing two points of a line always contains the entire line
5. Four points are sometimes coplanar
6. Two lines never meet in more than one point.
7. Two skew lines are never coplanar
8. Line TQ and Line QT are always the same line.
Step-by-step explanation:
Note: Coplanar means "In the same plane"
1. Each line exist in many planes. But different lines must share at least one plane for them to intersect. That is why intersecting lines are always coplanar.
2. Two planes never intersect at exactly one point because only lines intersect at a point. Planes can only intersect along a line.
3.Three points are always coplanar because in geometry, a group of points are coplanar because there is a geometric plane that they all lie on.
4. A plane containing two points of a line always contains the entire line. Yes
5. Four points are only sometimes coplanar because there is a probability that they may all not lie on the same plane
6. Two lines never meet in more than one point because lines are basically straight and cannot bend over to intersect at another point
7. Two skew lines are never coplanar because skews lines are lines that do not intersect and are never parallel.
8. Line TQ and Line QT are always the same line because a line is straight and extends from one point to the other. So, if a line is labelled TQ calling it QT means the same thing

Answer:
Remainder → (76)
Step-by-step explanation:
Given function;
f(x) = x² - 5
f(x) = x² + 0.x - 5
We have to divide this function by expression (x + 9).
x + 9) x² + 0.x - 5 (x - 9
x² + 9x
- 9x - 5
- 9x - 81
76
Therefore, by dividing the function 'f' by (x + 9) remainder is (76).
How can you use the distributive property to rewrite a quadratic expression in order to reveal its factors and zeros
Answer:
(x-rooot1)(x-root2)
Step-by-step explanation:
a quadratic ax²+bx+c=0 can be factor as those 2 pharanthesis
(x-rooot1) (x-root2)=0
and you can find the roots by making each parenthesis equal to 0 because of the zero product rule
x-root1 = 0, x=root1
x-root2 =0, x=root2

Which describes the correct procedure when converting a number from scientific notation to standard notation if the power of 10 is -10? A .Move the decimal point to the left. B. Move the decimal point to the right. C. Move the decimal point to the right. D. Subtract 20 from the number.
Answer:
A. Move the decimal point to the left
Step-by-step explanation:
Given that:
The scientific notation = 10⁻¹⁰
Let recall;
That the standard notation usually took the form of an inverse:
For example;
Let say 10⁻¹ will be [tex]\dfrac{1}{10}[/tex] in scientific notation;
SO, [tex]\dfrac{1}{10} = 0.1[/tex]
Now; we are given 10⁻¹⁰ as a scientific notation,
To standard notation, we get:
[tex]10^{-10} = \dfrac{1}{100}[/tex]
= 0.01
Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is -10.

The difference between six, and a number divided by four is sixteen
Answer:
'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:
[tex]\frac{6\:-\:x}{4}=16[/tex]Step-by-step explanation:
Let 'n' be the number
The difference between six and a number 'n' is written in an algebraic expression such as:
[tex]6 - x[/tex]
[tex]6-x[/tex] is obtained by 'subtracting, starting with 6'.Dividing 6-x by 4 will become:
[tex]\frac{6\:-\:x}{4}[/tex]so the sentence the difference between six, and a number divided by four is sixteen will become:
[tex]\frac{6\:-\:x}{4}=16[/tex]Therefore, 'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:
