Write an algebraic expression for the total amount of money raised from the sale of tickets. How much money was raised if the fund raiser sold 247 adult tickets and 390 children’s tickets? Let a= number of adult tickets and c= number of child tickets.
9514 1404 393
Answer:
11a +5c$4667Step-by-step explanation:
If 'a' adult tickets are sold for $11 each, the amount of money they sold for is ...
11a
If 'c' children's tickets are sold for $5 each, the amount of money they sold for is ...
5c
Then the expression for the total amount from the sale of tickets is ...
11a +5c . . . . total of money raised
__
The value of this expression for a=247 and c=390 is ...
11·247 +5·390 = 2717 +1950 = 4667
A total of $4667 was raised by the sale of tickets.
6^-6/6^-5 in the form 6^n
Answer:
6⁻¹
Step-by-step explanation:
6⁻⁶ = [tex]\frac{1}{6^6}[/tex] and 6⁻⁵ = [tex]\frac{1}{6^5}[/tex]
[tex]\frac{1}{6^6} * \frac{6^5}{1} = \frac{6^5}{6^6} = \frac{6^0}{6^1} = \frac{1}{6}[/tex] ** top & bottom same base 6, subtract exponent
[tex]\frac{1}{6}[/tex] = 6⁻¹

what is the slope (5,7) and (2,-2)
Answer:
slope = 3
Step-by-step explanation:
to find the slope you do (y2-y1)/(x2-x1)=m
so we can plug the points into this formula
(5,7) (2,-2)
x1 y1 x2 y2
-2-7/2-5=m
-9/-3=m
Simplifies to
3=m

Chaleah deposited $900 in a new account that earns 6% simple interest. After 2 years, how much interest will she have earned?
Answer:
$108
Step-by-step explanation:
Use the equation i = prt (interest = principle*rate*time):
Principle: $900
Rate: 0.06 (6%)
Time: 2 years
Put it all in an equation:
i = 900*0.06*2
i = $108

Note: Your equation seems a little unclear. But, I am assuming that your equation is:
[tex]e^x\:+\:e^{-1}=\:2[/tex]
Because my solution would still clear your concept about this topic, no matter what the question is.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]e^x\:+\:e^{-1}=\:2[/tex]
subtract [tex]e^{-1}[/tex] from both sides
[tex]e^x+e^{-1}-e^{-1}=2-e^{-1}[/tex]
[tex]e^x=2-\frac{1}{e}[/tex]
[tex]\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)[/tex]
[tex]\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)[/tex]
[tex]\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)[/tex] ∵ [tex]\:\:\ln \left(e\right)=1[/tex]
[tex]x=\ln \:\left(2-\frac{1}{e}\right)[/tex]
[tex]x=0.5[/tex]

Answer:
C. 36 degrees
Step-by-step explanation:
Exterior angles sum = 360 degrees
72+144=216
360-216=144
Supplementary angles(Angles on opposite sides of the transversal) sum = 180
180-144= 36
Therefore, x=36 degrees

Which inequality has the graph shown below?
Answers above ^
Answer:
The inequality the graph has shown is y < 2x - 3 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptFrom the given figure
∵ The line drawn is a dashed line
→ That means the sign of inequality without the equal sign
∴ The sign of the inequality is without the equal sign
∵ The shaded area is under the line
→ That means the sign of the inequality is smaller than
∴ The sign of the inequality is <
∵ The line intersects the y-axis at point (0, -3)
→ That means the y-intercept is -3
∴ The y-intercept = -3 ⇒ (value of b in the equation of the line)
∵ There is only one answer has sigh < and y-intercept -3
∴ The inequality the graph has shown is y < 2x - 3

Answer:
x = 9
Step-by-step explanation:
First equation = 4x - 8
Second equation = 7x - 35
Seperate the equation with an equal sign to make it an equality equation and solve for X so :
4x - 8 = 7x - 35 (Given)
-3x - 8 = -35 (Subtraction property of equality)
-3x = -27 (Addition property of equality)
x = 9 (Division property of equality)
Solution:
x = 9
22
Solve for x.
3x - 5 = 10
x equals.....
help
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
[tex]3x - 5 = 10[/tex]
We want to isolate the x.
[tex]3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5[/tex]
[tex]3x = 15[/tex]
Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.
[tex]\frac{3x}{3} \;=\;\frac{15}{3}[/tex]
[tex]x = 5[/tex]

To solve for x, we need to first get it all by itself.
[tex]\twoheadrightarrow\sf3x-5=10[/tex]
[tex]\bullet[/tex] Add 5 to both sides
[tex]\twoheadrightarrow\sf3x=15[/tex]
[tex]\bullet[/tex] Divide by 3 on both sides
