1.4-28/x
Solve for x
Answer:
20
Step-by-step explanation:
1.4-28/x = 0
bring 1.4 to the right hand side
-28/x = -1.4
bring the x to the right hand side
-28 = -1.4x
switch the positions of -28 and -1.4x
-1.4x = -28
divide -28 by -1.4
x = -28/-1.4
x = 20
someone help a-a+b; use a=6 and b=4
Answer:
4
If A=6 then you would have to plug that in for a which would become 6-6 which equals 0.Then you would have to plug in 4 for b so you would do 0+4= your answer of 4.

Step-by-step explanation:
The school that Stefan goes to is selling tickets to a spring musical. On the first day of ticket sales the school sold 1 senior citizen ticket and 14 student tickets for a total of $225. The school took in $120 on the second day by selling 7 senior citizen tickets and 1 student ticket. What is the price each of one senior citizen ticket and one student ticket?
x = price of a senior ticket
y = price of a student ticket
First day: x + 14y = $225
Second day: 7x + y = $120
Let's solve this system of equations by substitution
Subtract 14y from both sides on our first equation
First day: x = $225 - 14y
Substitute this value into our second equation for x
7($225 - 14y) + y = $120
Distribute the 7
$1575 - 98y + y = $120
Combine like terms
$1575 - 97y = $120
Subtract $1575 from both sides
-97y = -1455
Divide both sides by -97
y = $15
Plug this value into our first equation
x + 14(15) = $225
Simplify
x + $210 = $225
Subtract $210 from both sides
x = $15
The senior and student tickets cost $15
Use a number line to add the following: 14 + (-11)
Add.
Adding a negative number is the same as subtracting a positive number.
14 + (-11) = 14 - 11
We start at the point 14 on a number line.
Since we are subtracting, we are going to left -11 units on the number line.
We will land on the point "3"
Best of Luck!

What is the slope of the line that contains the points (-2, 7) and (2, 3)? O A. -4 OB. 4 O C. -1 O D. 1 SUBM
Answer:
- 1
Step-by-step explanation:
[tex]slope = \frac{3 - 7}{2 - ( - 2)} = \frac{ - 4}{2 + 2} = - \frac{4}{4} = - 1 \\ [/tex]
The slope of the line that contains the points (-2, 7) and (2, 3) is -1.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have the points (-2, 7) and (2, 3).
So, the slope of line
= (3 -7)/ (2- (-2))
= (-4) / (4)
= -1
So, the slope of line is -1.

Is 13 a rational number? And why
Answer: A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero if you’re working with a number with a long line of different decimals, then your number is irrational! If you’re working with an integer or a number with terminal or repeating decimals (like 1.333333), then your number is rational! and 13 is a rational number since it can be written as a fraction as well like 13/1

Answer:
y = 58 x= 122
Step-by-step explanation:
y = 180-90-38+6
x=180-y
Answer:
x = 52º
y = 134º
Step-by-step explanation:
x = 90-38
x = 52º
------------------------------
x + y - 6 = 180º
52 + y - 6 = 180º
y = 180 + 6 - 52
y = 134º
