Jayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.

You start at (6, 7). You move right 3 units. Where do you end?
Answer:
(9, 7) is where you would end
Step-by-step explanation:
We know that;
x-value = 6
y-value = 7
We also know that by moving 3 units right u will add 3 to the x-value, therefore;
Final x-value = 6 + 3 = 9
Final y-value = 7 (there is no change)
Final coordinates: (9, 7)

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase
Given:
Two weeks ago, the cost of tickets = $30
Now, the cost of tickets = $39
To find:
The percent increase.
Solution:
We have,
Initial value = $30
New value = $39
Formula for percentage increase is:
[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
Using this formula, we get
[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]
[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]
[tex]\%\text{increase}=3\times 10[/tex]
[tex]\%\text{increase}=30[/tex]
Therefore, the percent increase in the cost of tickets is 30%.

In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). If R represents the third vertex in the triangle and R is located in the third quadrant, what is the length of PR?
PR = 5 units.
Step-by-step explanation:Given:
Right triangle
Hypotenuse = P(–3, 2), Q(1, –3)
R = located in the third quadrant.
To calculate the length of PR,
(i) First make a sketch of the points P and Q. The diagram is attached to this response.
(ii) As shown in the diagram, the point R is located in the third quadrant and its distance from P is from point -3 to 2 on the y-axis.
There are 5 points between -3 and 2. Therefore, the length PR = 5 units

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?
Answer:
As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.
Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.
Subtract the 2 hours from 10am:
= 10 - 2
= 8am
Subtract the 15 minutes from 45:
= 45 - 15
= 30
Put that together:
= 8:30 am
They left their house at 8:30 am using this scenario.

If I need to pour a cement sidewalk five feet wide and 250 feet long, the cost of the cement is 30 afoot, what will I have to pay.
Answer:
$37500
Step-by-step explanation:
Given data
Width of side walk= 5ft
Lenght= 250ft
Cost per square foot= $30
Hence the area of the side walk= 5*250
= 1250ft^2
Hence the cost = 30*1250
=$37500
