Which expression is equivalent to 1/3 p + 15? (4 points)
Select one:
a.1/3 (p + 45)
b. 1/3 (p + 5)

Tom has 28 milk chocolates, and Emily has 24 dark chocolates. They have to divide these chocolates into small packets that each have the same number of dark chocolates and the same number of milk chocolates. They also want to use all of the chocolates.
The maximum number of packets they can make is
. To make the maximum number of packets, each packet should have
milk chocolates and
dark chocolates.
4 milk chocolatero need to be removed to have even amounts
24+24= 48
24 packets with 1 of each(2 count) is one possibility.
You can have less packets with more chocolates inside like 12 packets with 4 count(2 of each)
Any combination with result 48. To use al chocolatesl : 4 packets:Each packet has 6dark and 7milk choc

Answer:
Y= 0
Step-by-step explanation:
A proportional relationship is when two numbers change at a constant rate. They always are modeled by y = kx, which in this case, would be y = 5/3x. The y-intercept would be added to the equation, as y = kx + b, in this case would be y = 5/3x + 0, or the previous equation.

Figure D’E’F’G’ is a dilation with center (0, 0) of figure DEFG. What is the scale factor?
Answer:
0,0
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Lets start by finding out the cordinates first!
these are the ones we start off with!
D (1,1)
E (2,2)
F (4,2)
G (3,1)
now we need to find the prime image cords.
D' (4,4)
E' (8,8)
F' (16,8)
G' (12,4)
now what we are tying to find is the scale factor, so we need to check what number is multipled by those cordinates to get the prime cordinates.
D is (1,1) and D' is (4,4) but we know that 1x4 is 4 so 4 is the scale factor that we multiply all the numbers by ! i hope that made sense !

Kieran subscribes to a text messaging service on his cell phone. His monthly bill for the service is given by the equation b = 0.25t, where b is the bill amount and t is the number of texts.
The constant of proportionality in terms of cost per text is ____
It is not 8.
Answer:
25 cents
Step-by-step explanation:
The question doesn't make a lot of sense, but I think the answer is $0.25, because In the equation b=0.25t, each text costs 25 cents
b=0.25t
The cost of proportionality is 0.25

Which size can of soup shown in the table has the lowest unit price?
The can of size 10 has the lowest unit price.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity.
We have to find the unit rate.
For size 10 :
Cost of 10 oz of soup = $0.79
Cost of 1 oz of soup = 0.79 / 10 = 0.079
For size 15 :
Cost of 15 oz of soup = $1.29
Cost of 1 oz of soup = 1.29 / 15 = $0.086
For size 18 :
Cost of 18 oz of soup = $2.16
Cost of 1 oz of soup = 2.16 / 18 = $0.12
For size 32 :
Cost of 32 oz of soup = $3.19
Cost of 1 oz of soup = 3.19 / 32 = $0.0997
The smallest unit price is for can of size 10.
Hence the lowest unit price is for the can of size 10.

What is the slope of the line?
Answer:
2/3
Step-by-step explanation:
Step 1
(1,2) (4,4)
First we are going to pick two point on the line.
Step 2
(y2-y1) / (x2-x1)
(4-2) / (4-1)
in the first set we label x as x1 and y as y1, then we do the same with the other set but with x turning into x2 and y turning into y2. We then plug them into the equation.
Step 3
(2)/(3)
or
2/3
Now we solve what is in the parentheses (4-2) is 2, and (4-1) is 3. We then take away the parentheses and have 2/3. keep 2/3 as a fraction, do not change it to a decimal.

Answer:
7.5
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2([tex]\pi \\[/tex])r
r = 5 therefore: 2([tex]\pi \\[/tex])5 = 10[tex]\pi \\[/tex]
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us 7.5[tex]\pi \\[/tex], or 23.55

1. How do you subtract an integer from another integer without using a number line?
2. Rewrite each following subtraction problems as addition problems
1) 5-11 2) 15- 21
3) 0-(-5) 4) 19-(-19)
5)-3-(-5) 6)-87-(-87)
7)-17-1
3. When Tom found the difference -11-(-4), he got -15. What might Tom have done wrong?
4. When you subtract one negative integer from another, will you answer be greater than or less than the integer you started with? Explain your reasoning and give an example.
5. Theo had a balance of -$4 in his savings account. After making a deposit, he has $25 in his account. What is the overall change to his account? Show all your steps.
Answer:
1) Remember to change the signs when necessary. For example, when you're subtracting a negative with another negative, you add the two numbers to form a bigger negative.
2)
1)) -6 + 11 = 5
2)) -6 + 21 = 15
3)) 5 + 0 = 0
4)) 19 + 19 = 38
5)) (-5) + (-3)
6)) -87 + 87 = 0
7)) -1 + -17 = -18
3) Tom didn't change the sign to make a +, instead he left it as one negative sign and a subtraction sign.
4) The answer will be of a greater value as the two negatives would cancel each other out. For example, -9 - (-9) would end up being 0 as the sign change would make one 9 positive.
5) $-4 + $29 = $25 He added $29 dollars to his bank account, turning himself out of debt.
