Answer:
c = -20
Step-by-step explanation:
-21=1/2c-11
-21+11=1/2c
-10=1/2c
-10*2=c
-20=c
Answer:
c = - 20
Step-by-step explanation:
Given
- 21 = [tex]\frac{1}{2}[/tex] c - 11 ( add 11 to both sides )
- 10 = [tex]\frac{1}{2}[/tex] c ( multiply both sides by 2 to clear the fraction )
- 20 = c , that is
c = - 20

Step-by-step explanation:
1. Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.

A music festival offers one-day and three-day passes. A one day pass costs $100 and a three-day pass costs $250. write an expression for the total ticket sales if (n) one day passes and (t) three day passes are sold.
Answer:
100n+250t
Step-by-step explanation:
cost of the1 one day pass=100
cost of n one day passes=100n
cost of the 1 three day pass=250
cost of t three day passes=250t
Total sale= 100n+250t
The expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Cost of one-day passes, n = $100
Cost of three-day passes, t = $250
So, Total tickets sold = Cost of one-day passes + Cost of three-day passes
⇒ Total tickets sold = n + t
⇒ n + t = $100 + $250
⇒ n + t = $350
which is the required expression for total tickets sold.
Thus, the expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

if m<2=98, m<3=23 and m<8=70, find each measure
Answer:
Step-by-step explanation:
From the picture attached,
There are two parallel lines intersected by three transverse lines.
m∠2 = 98°, m∠3 = 23°, m∠8 = 70°
a). Since ∠1 and ∠2 are linear pairs,
m∠1 + m∠2 = 180°
m∠1 + 98° = 180°
m∠1 = 180 - 98
m∠1 = 82°
b). m∠4 = m∠7 [Corresponding angles]
m∠7 = 180° - (m∠2 + m∠3) [Property of a triangle]
= 180 - (98 + 23)
= 180 - 121
= 59°
m∠4 = m∠7 = 59°
c). m∠5 = 180° - (m∠3 + m∠4)
= 180° - (23° + 59°)
= 180° - 82°
= 98°
d). m∠6 = 180° - (m∠7 + m∠8)
= 180° - (59° + 70°)
= 180 - 129
= 51°
e). m∠7 = 59° [Calculated in part b]
f). m∠9 = 180° - (m∠4 + m∠8) [Property of a triangle]
= 180° - (59 + 70)°
= 180 - 129
= 51°
g). m∠10 = 180° - m∠9
= 180 - 51
= 129°
An electric company calculates a persons monthly bill from the number of kilowatt kWh, x, used
The function (in photo ) determines the bill
How much is the bill for a person who uses 400 kWh in a month
A. 50
B. 60
C. 40
D. 30
Answer:
Option (A)
Step-by-step explanation:
From the given piecewise function that represent the amount of bill from number of units of electricity used is 'x' kWh.
b(x) = 0.10x when x ≤ 200
0.15(x - 200) + 20 when x > 200
For x = 400 kWh,
Function which represents the expenses of the bill,
b(400) = 0.15(400 - 200) + 20 [Since x > 200]
= 0.15(200) + 20
= 30 + 20
= $50
Therefore, Option (A) will be the answer.

[tex]E=\frac{mv^2}{2}[/tex]
Step-by-step explanation:
[tex]m=\frac{2E}{v^{2} }[/tex]
Multiply [tex]v^2[/tex] to both sides:
[tex]m*v^2=\frac{2E}{v^{2} } *v^2[/tex]
[tex]mv^2=2E[/tex]
Switch sides:
[tex]2E=mv^2[/tex]
Divide both sides by 2:

explain the difference between an Expression and an Equation.
Answer:
An equation has a set value or a mathematical sentence that contains an = sign. An expression is a math sentence that contains numbers, letters, and symbols( not an = tho) and the value of the variable can change.Equations and expressions are often encountered when understanding mathematical concepts. If compared with language, expressions are like phrases while equations are complete sentences. Expressions have no relations whereas equations reveal relationships. You need to solve equations while expressions can only be evaluated.Step-by-step explanation:
pls give brainliest if i helped:)
The difference between the expression and an equation is explained below:
Difference between the equation and expression:The equation represents the mathematical value while the expression could include the numbers, letters, etc. The expression should be treated as phrases while the equations are considered to be complete sentences. The expression does not show any kind of relations while the equation should show the relationship.
In this way, it should be differentiated.

Jorge’s printer can print 36 pages in 18 minutes. How many pages can it print in 1 hour
Answer:
120 pages can be printed in 1 hour.
Step-by-step explanation:
First divide 36 by 18 to figure out how many pages can be printed in a minute.
Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.
Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.
Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.
