13- (x + 6) = 4x - 3
Answers
Step-by-step explanation:
13 - (x + 6) = 4x - 3
13 -x -6 = 4x - 3
Group like terms
13 - 6 + 3 = 4x + x
13 - 3 = 5x
10 = 5x
Divide both sides by 5
10/5 = 5x/5
2 = x
Therefore, x is equal to 2.

The admission fee at an amusement park is $15.50 for children and $20.00 for adults. One day 217 people entered the park and the total admissions fees collected was $3.782
Define your variables as
"C" = # of children
"a" = # of adults
Write a system of equations to represent this information solve the system to find out how many children and how many adults came to the amusement park that day.
Answers
Answer:
Children = 124
Adults = 93
Step-by-step explanation:
x = children
y = adults
x + y = 217
x = 217 - y
15.50x + 20y = 3782
15.50 (217-y) + 20y = 3782
3363.50 - 15.50y + 20y = 3782
4.5y = 3782 - 3363:50
y = 418.50/4.5
y = 93
x + 93 = 217
x = 217 - 93
x = 124

Answer:
JK = 42 , KL = 78
Step-by-step explanation:
JK + KL = JL , substitute values
4x + 6 + 7x + 15 = 129 , that is
11x + 21 = 120 ( subtract 21 from both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

7v- 5 ≥ 65 or -3v - 2 ≥ -2
Answers
The result if the inequality expressions are v ≥ 10 and v < 0
Given the following inequality expression
7v- 5 ≥ 65 or -3v - 2 ≥ -2
Solve the inequality individually
7v - 5 ≥ 65
Add 5 to both sides
7v - 5 + 5 ≥ 65 +5
7v ≥ 70
v ≥ 70/7
v ≥ 10
For the inequality-3v - 2 ≥ -2
Add 2 to both sides
-3v - 2 + 2≥ -2 + 2
-3v ≥ 0
v < 0
Hence the result if the inequality expressions are v ≥ 10 and v < 0

what is 5x(2x+7)+x(3x-5 do you know
Answers
Answer:
43xx
Step-by-step explanation:
5x(2x+7)+x(3x-5)
first, do the equations inside the parentheses
2x+7=9x
3x-5=-2x
so,
5x(9x)+x(-2x)
Next, do 5x times 9x
(5x) x (9x) = 45
so,
45+x(-2x)
Next, do x times (-2x)
(x) x (-2x)=-2xx
so,
45+-2xx

Step-by-step explanation:
the A point is in line with 10 squared and its in line with the 17 squared
The measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The graph shows the triangle CAT.
If a rotation takes triangle CAT to C'A'T',
then from the definition of rotation transformation the size and shape of the figure stays exactly the same.
Thus the measure of C'T' is same as CT.
⇒ [tex]C'T' =\sqrt{17}[/tex]
Hence we can conclude that the measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.

A store sells notepads in packages of 24 and packages of 6. The organizers of a conference needs to prepare at least 200 notepads for the event. Would they have enough notepads if they bought five packages of 24 and fifteen packages of 6 ?
Answers
Answer: Yes they would have enough notepads
Step-by-step explanation:
24 * 5 = 120
15 * 6 = 90
120 + 90 = 210
The organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.
Given that, a store sells notepads in packages of 24 and packages of 6.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, the number of note pads with five packages of 24
24 × 5 = 120
The number of note pads with fifteen packages of 6
15 × 6 = 90
Total number of note pads
= 120 + 90 = 210
Therefore, the organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.
