Answer:
60
Step-by-step explanation:
here are 360° used in a whole pie chart
Using proportion
30° → 5 people
360° → 5 × 360 / 30 = 5 × 12 = 60
There are 60 people altogether

x + 2x + 12y + 4
What are the variables of this expression?
Answer:
3x+12y+4 -- is the simplified version, variables would be x and y
i need help on the last part!
Answer:
0; (0, 0); 144; (3, 144)
Step-by-step explanation:
Y = distance (m)
X = time (hr)
X = 48x
If a car travels for 0 hours, it will travel __ mile(s).
y = 48x
Plug in 0 hours for x (time in hours)
y = 48(0)
Any number mutliplied by 0 equals 0
y = 0
If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).
(0, 0) limits our options to graphs B and D
Car travels 144 miles in 3 hours
To find how many miles it travels in 1 hour, divide 144 miles by 3 hours
144 ÷ 3 = 48
In 1 hour, a car travels 48 miles
If 48 × 3 = 144, then 48 × 4 = ?
48 × 4 = 192
When looking at graph D, there are 4 lines above 0
Counting by 48, it perfectly fits 192 by the fourth line
From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting
Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144
Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship
Solve this linear equation for p.
2.6(5.5p – 12.4) = 127.92
1. Distributive property: 14.3p − 32.24 = 127.92
2. Addition property of equality: 14.3p − 32.24 + 32.24 = 127.92 + 32.24
14.3p = 160.16
3. Division property of equality:
14.3p
14.3
=
160.16
14.3
4. Solution: p =

Mauricio bought 6.75 yards of fabric for a total of $47.50
About how much was the cost per yard? Explain why your
answer is reasonable. ( brainliest included for correct answer)
Answer:
$7.04
Step-by-step explanation:
47.50/6.75 which is about $7.04
My answer is reasonable because 47.50 is close to 49 and 6.75 is close to 7 and 49/7 is 7, which is about 7.04.
Hope this helps :D
Answer:
About $7.04 / yard.
Step-by-step explanation:
We divide the total cost by the length of fabric.
Cost per yard = 47.50 / 6.75
= 7.037
= $7.04 to the nearest cent.
This is reasonable because 6.75 yards is close to 7 yards and 7 * $7 = $49.

Vanessa solved 244 problems in a recent Mathathon. She solved four times as many problems as her friend Bethany. (a) Write a math sentence to determine the number of problems (p) Bethany solved. (b) How many problems did Bethany solve?
Answer: (a) 61
(B) 61
Step-by-step explanation: If she solved 244 problems, and at the same time she solved four times more than bethany, Therefore 244÷ 4 = 61
Select all equations that can result from adding these
two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
(Select all that apply)
Answer:
Step-by-step explanation:
x + y = 12 ---------------(1)
3x - 5y = 4 --------------(2)
(1)*5 + (2) * 1 then,
5x + 3x = 60 + 4
8x = 64
x = 64/8
x = 8
from (1), 8 + y = 12
y = 4
apply(x,y)=(8,4) to these function.
-2x-4y = -32 no
-2x+6y=8 yes
like this
The required expression after the addition of the equations is 4x - 4y = 16, and the expression after the subtracting of the equations is -2x +6y = 8.
Given that,
To select all equations that can result from adding these two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
Addition
x + y = 12
+ 3x - 5y = 4
--------------------
4x - 4y = 16
Subtraction,
x + y = 12
- (3x - 5y = 4)
--------------------
x + y = 12
- 3x + 5y = -4
---------------------
-2x + 6y = 8
Thus, the required expression after the addition of the equations is 4x - 4y = 16, and the expression after the subtracting of the equations is -2x +6y = 8.

There are many properties of exponents. These properties are used to make problems with exponents simpler.
Choose one of the properties and explain why it is true. Then write a numerical expression and use the property you chose to simplify the expression.
Answer:
The product rule of exponents
Step-by-step explanation:
An expression is 6xa^3 x 3xa^4
This can be hard to answer but there are three rule. 1st you keep the base which is a. 2nd is add the exponents which are 4 and 3. 3rd is multiply the coefficient which is 6 and 3. and this answer would be 18xa^7.
