combine like terms
-6<-1x
divide by negative 1 on both sides
flip the sign when dividing by a negative number
6>x is the answer.
Answer:
[tex]\boxed { x < 6}[/tex]
Step-by-step explanation:
Solve the following inequality:
[tex]-6 < 3x - 4x[/tex]
-Combine like terms:
[tex]-6 < 3x - 4x[/tex]
[tex]-6 < -x[/tex]
-Switch sides:
[tex]-6 < -x[/tex]
[tex]-x > -6[/tex]
-When you are dividing an integer by a negative integer, then the inequality sign would change. So, to get the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} > \frac{-6}{-x}[/tex]
[tex]\boxed { x < 6}[/tex]

If a polygon has exactly 4 sides, it is a quadrilateral. State the contrapositive of the conditional statement. A) If a polygon is a quadrilateral, it has exactly 4 sides. B) If a polygon is a quadrilateral, it does not have exactly 4 sides. C) If a polygon is not a quadrilateral, it does not have exactly 4 sides. D) If a polygon does not have exactly 4 sides, it is not a quadrilateral.
Answer: I think the answer is D
Step-by-step explanation:
Option - C is the correct option.
We have a statement - If a polygon has exactly 4 sides, it is a quadrilateral.
We have to write the contrapositive of this conditional statement.
What do you mean by Contrapositive of the Conditional statement ?A combination of the converse and the inverse is called Contrapositive of the Conditional statement. Contrapositive will replace if with then and vice - versa and after that both parts are negated.
According to the question, we have a statement -
If a polygon has exactly 4 sides, it is a quadrilateral.
Firstly, replace ' if ' with ' they ' and vice - versa. We get -
If a polygon is a quadrilateral, than it does have exactly four sides.
Now, negate it -
If a polygon is not a quadrilateral, it does not have exactly 4 sides.
Hence, Option C is correct.

a student has some $1 and $5 bills in his wallet. He has a total of 17 bills that are worth $53. How many of each type of bill does he have
Answer:
$1 bills = x and $5 bills = y
x+y = 17 - that expresses the number of bills.
1x + 5y = 53.
Solve the first for x in terms of y and substitute that into the second.
x = 17 - y
17 - y + 5y =53
17 +4y = 53
4y = 36
y = 9
Substitute that back into the first equation: x + 9 = 17 and then x = 8

Y- 5 + 16 = 21/2 = 10.5
You add the x coordinates together then divide by 2, then do the same with the y coordinates.
3x + 5y + z = 2
x + 2y + 3z = 6
2x + 4y + 2z = 9
10 + 6x = 15 + 9x – 3x
Answer:
No solution
Step-by-step explanation:
Step 1: Write equation
10 + 6x = 15 + 9x - 3x
Step 2: Solve for x
Combine like terms: 10 + 6x = 15 + 6xSubtract 6x on both sides: 10 ≠ 15Here, we see that x would equal no solutions. You can also think of it as parallel lines; they have the same slope but different y-intercepts, so they will never intersect.
Kira started a game at 4:37 PM and finished it at 5:16 PM.
How long did it take her? Give your answer in minutes.
Answer:
39
Step-by-step explanation:
4:37 till 5:00 is 23 minutes.
+ 16 minutes
= 23 + 16
Answer:
39 minutes
Step-by-step explanation:
First, find how much time passed between 4:37 PM and 5 PM.
Since there are 60 minutes in an hour, subtract 37 from 60:
60 - 37
= 23
There are 16 minutes in between 5 PM and 5:16 PM.
So, add the 23 minutes to 16:
23 + 16
= 39
So, it took her 39 minutes

2x+3=x-4
Answer:
x = -7
Step-by-step explanation:
Solve for x:
2 x + 3 = x - 4
Hint: | Move terms with x to the left-hand side.
Subtract x from both sides:
(2 x - x) + 3 = (x - x) - 4
Hint: | Combine like terms in 2 x - x.
2 x - x = x:
x + 3 = (x - x) - 4
Hint: | Look for the difference of two identical terms.
x - x = 0:
x + 3 = -4
Hint: | Isolate terms with x to the left hand side.
Subtract 3 from both sides:
x + (3 - 3) = -3 - 4
Hint: | Look for the difference of two identical terms.
3 - 3 = 0:
x = -3 - 4
Hint: | Evaluate -3 - 4.
-3 - 4 = -7:
Answer: x = -7

Maya and carlos was selling cookie dough for school fundraiser customers can buy packages of chocolate-chip cookie dough and packages of gingerbread cookie dough my sold 8 packages of chocolate chip cookie dough and 12 packages of gingerbread cookie dough for a total of $374 carlos o two packages of chocolate chip cookie dough and four packages of gingerbread cookie dough for a total of $113 final cost of one package of chocolate chip cookie dough and one package of gingerbread cookie dough
Answer:
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
Step-by-step explanation:
Assume;
Cost of chip cookies = c
Cost of ginger cookies = g
So,
Maya's sales = 8c + 12g = 374 .....Eq1
Carlo's sales = 2c + 4g = 113 .......Eq2
4 x eq2
So
8c + 16g = 452......Eq3
Eq 3 - Eq 1
4g = 78
g = 19.5
and
c = 17.5
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5

write a paragraph proof for the following conjecture
Given m∠1 + m∠2 = m∠4
Prove: m∠3 + m∠1 + m∠2 = 180°
m∠1 + m∠2 = m ∠4 , under the exterior angle property of a triangle which says that sum of the interior opposite angles of an exterior angle will be equal to the measure of the exterior angle .
To prove that m∠3 + m ∠1 + m∠2 = 180° , let us use the angle sum property .
= Angle sum property = Sum of the three interior angles in a triangle will be equal to 180° .
= Since ∠1 , ∠2 and ∠3 are the interior angles of this triangle , their sum will be equal to 180° .
Hence proved that m∠1 + m∠2 + m∠3 = 180°
∴ m∠1 + m∠2 + m∠3 = 180° under the angle sum property of a triangle .
8x = 10x + 20
Could you guys explain as well?
Answer:
x= -10
Step-by-step explanation:
-8x+10x+20=0
2x+20=0
2x=0-20
2x=-20
x=-20/2
x= -10
Answer:
x = -10
Step-by-step explanation:
8x (-10x)= 10x +20 (-10x)
subtract 10x from both sides of the equation
-2x/-2 = 20/-2
divide both sides by -2
x = -10
In Crestview Middle School, 12 out of 16 students are right handed. If there are 400 students in the school, how many are right handed?
Answer:
the answer is 300
Step-by-step explanation
there are 16 people so we divide that by the total number of students
400 divided by 16 = 25
since there are 12 right handed in each group we multpily it by 12
25 x 12 = 300
and theres your answer!
