I just need help with these few questions... please give me actual answers.
Answer:
Step-by-step explanation:
1. -7 = w + 5
w = -12
(-12 + 5 = -7)
2. -4p + 38 = 10
-38 -38
-4p = -28
/-4 /-4
p = 7
3. -3 1/2 = -1 1/4b
/1.25 /1.25
-2 4/5 = -b
2 4/5 = b
or
2.8 = b
Answer:
Step-by-step explanation:
Question 1:
-7 = w + 5
- 5 - 5
-12 = w
w = -12
Question 2:
-4p + 38 = 10
- 38 - 38
-4p = -28
----- ----- fraction bar... -4p divided by -4, -28 divided by -4
-4 -4
p = 7
Question 3:
-3 1/2 = -1 1/4b
- 7 = - 5
----- ----- b
2 4
4 -7 -5 4
---- x ----- = ------ x ----- b
-5 2 4 -5
-28
---- = b
-10
-28 2 14
----- divided by ---- = -----
-10 2 5
b = 2 4/5

if all functions are relations, are all relations functions? Explain your answer
Answer:
No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.
This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.

The sum of 5.5 and twice a number is -10
What is the number?
n = 7.75
n=2.125
n= -7.75
n=-2.125
Answer:
n=-7.75
Step-by-step explanation:
Based on the given conditions, formulate: 5.5+2×X=-10
Rearrange unknown terms to the left side of the equation:2x=-10-5.5
Calculate the sum or difference:2x=-15.5
Divide both sides of the equation by the coefficient of variable:x=-15.5/2
Multiply both the numerator and denominator with the same integer:-155/20
Cross out the common factor:-31/4
get the result: -7.75
Answer: -7.75

The library has 3,121 magazines. Each bin holds 73 magazines. How many magazines will be in the partially filled bin?
Answer:
55
Step-by-step explanation:
3121/73=42 R55
Answer: 55 magazines will be in the partially filled bin.
Step-by-step explanation:
3,121 / 73 = 42.75, or 42 whole bins.
42 * 73 = 3,066
3,121 - 3,066 = 55

Answer:
10/12 simplified 5/6
Answer:
A) [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
So solve, change the sign into multiplication and use the reciprocal of the second number.
To find the reciprocal, flip the numerator and the denominator.
The reciprocal of 4/5 is 5/4.
So you have [tex]\frac{2}{3}[/tex]×[tex]\frac{5}{4}[/tex]
Multiply like a normal expression.
You get 10/12, which can be simplified to [tex]\frac{5}{6}[/tex]

A survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.
Students
A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.
Teachers
A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.
Based on the shape of the two dot plots, which statements correctly compare them? Select three choices.
Answer:
the answer is a: The mode for the students is 2 and the mode for the teachers is 4.
Hope this helps, have a nice day/night! :D
Answer:
The modle for the students is 2 and for the teachers is 4. A is your answer
Step-by-step explanation:
Select all the equations that have {4} as its solution set. 5 + 2x = 3x + 37−x=12x79−3x=12x+19x2+3=10x−21
5 + 2x = 3x + 3
7−x=12x
79−3x=12x+19
x2+3=10x−21
Answer:
Option 3 (79−3x=12x+19)
Step-by-step explanation:
When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.
Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.
Given that, the equations that have {4} as its solution set.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
1) Solution of an equation 5 + 2x = 3x + 3 is
3x-2x=5-3
⇒x=2
2) Solution of an equation 7−x=12x is
7−x=12x
⇒12x+x=7
⇒13x=7
⇒x=7/13
3) Solution of an equation 79−3x=12x+19 is
12x+3x=79-19
⇒15x=60
⇒x=4
4) Solution of an equation x²+3=10x−21 is
x²+3=10x−21
⇒ x²-10x+24=0
⇒ x²-6x-4x+24=0
⇒ x(x-6)-4(x-6)=0
⇒ (x-6)(x-4)=0
⇒ x=6 or 4
Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Answer:
29.5 inches
Step-by-step explanation:
Eva is 1.5 inches shorter than half of Maria's height, so to determine Eva's height, we would subtract 1.5 from 31, half of Maria's height. Our difference is 29.5. Eva is 29.5 inches tall.

Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.)
Answer:
we can see that the x or the first number in both are 2 so there is no distance there, where there is a distance is the y which to find out we can just do 2.5-1.2=1.3
the distance between the two points is 1.3
