Mya and Ashley are buying tickets to the art show. Adult
tickets cost $3 more than the student tickets. Mya buys 7
tickets and 6 adult tickets. Ashley buys 15 student tickets and
1 adult ticket. They both spend the same amount of money
on their tickets. What is the price of one adult ticket?
Answer:
$8
Step-by-step explanation:
a: adult tickets
s: student tickets
Mya: 7s + 6(3+s)
Ashley: 15s + 1(3+s)
Mya: 7s + 6(3+s) –> 7s + 18 +6s –> 13s +18
Ashley: 15s + 1(3+s) –> 15s + 3 + s –> 16s +3
13s + 18 = 16s +3
15 = 3s, divide 3 from both sides so s = 5
so students tickets cost $5
since adult tickets cost $3 more than student tickets:
($3 + $5) = $8 for an adult ticket.
Answer:
the answer is $8

1.24$
6.43$
2.13$
with these numbers i need to round to the nearest dollar (SHOW WORK PLS) estimate total cost.
Answer:
$10
Step-by-step explanation:
1.24+6.43+2.13= 9.8
9.8 rounded to the nearest dollar is $10.
You can do it a different way, rounding the numbers before adding.
this would be:
1.3+6.4+2.1= 9.8
Either way, you get the same number. 9.8
And 9.8 rounded to the nearest dollar is $10
All the best, -Crispin
Answer:
$1.00
$6.00
$2.00
The estimated cost is $9.00
Step-by-step explanation:
1.24 = The 2 in 1.24 is smaller than 5 so you round down
6.43 = The 4 in 6.43 is smaller than 5 so you round down
2.13 = The 1 in 2.13 is smaller than 5 so you round down

Let Tn, be the number of dots in figure.
How many dots are there in figure 30?
Look at the picture (don't mind of the highlighted ones).
Answer:
4294967293 dots
Step-by-step explanation:
Figure 1 has 5 dots.
Figure 2 has 13 dots.
Figure 3 has 29 dots.
Subtract and find different of each term:
13-5 = 829-13 = 16Let [tex]\displaystyle \large{b_n}[/tex] be sequence of difference (and the sequence appears to be geometric.)
So for [tex]\displaystyle \large{b_n}[/tex], find the common ratio which is 2.
Hence, [tex]\displaystyle \large{b_n = 8(2)^{n-1}}[/tex] - recall geometric sequence formula below:
[tex]\displaystyle \large{a_n = a_1r^{n-1}}[/tex]
The sequence of difference [tex]\displaystyle \large{b_n=8(2)^{n-1}}[/tex] can be simplified to:
[tex]\displaystyle \large{b_n=2^3(2)^{n-1}}\\\displaystyle \large{b_n=2^{n+2}}[/tex]
Now to find the original sequence:
[tex]\displaystyle \large{a_n = a_1 + \sum_{k=1}^{n-1}b_k}[/tex]
Hence:
[tex]\displaystyle \large{T_n=5+\sum_{k=1}^{n-1}8(2)^{k-1}}[/tex]
Recall:
[tex]\displaystyle \large{\sum_{k=1}^{n-1} a_1r^{n-1} =a_1\left( \dfrac{1-r^{n-1}}{1-r}\right)}[/tex]
Therefore:
[tex]\displaystyle \large{T_n=5+\sum_{k=1}^{n-1}8(2)^{k-1}}\\\displaystyle \large{T_n=5+8\left(\dfrac{1-2^{n-1}}{1-2}\right)}\\\displaystyle \large{T_n=5+8\left(\dfrac{1-2^{n-1}}{-1}\right)}\\\\\displaystyle \large{T_n=5+8(-1+2^{n-1})}\\\displaystyle \large{T_n=5-8+8(2)^{n-1}}\\\displaystyle \large{T_n=2^{n+2}-3}[/tex]
Therefore, the sequence for 5,13,29 is [tex]\displaystyle \large{2^{n+2}-3}[/tex].
Therefore, in figure 30:
[tex]\displaystyle \large{T_{30}=2^{30+2}-3}\\\displaystyle \large{T_{30}=2^{32}-3}\\\displaystyle \large{T_{30}=4294967293}[/tex]
Therefore, there are 4294967293 dots in figure 30
What is the value of x?
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
15x + 3 + 3x - 1 + 52 = 180
15x + 3x + 3 - 1 + 52= 180
Combine like terms.
18x + 54 = 180
To find the vlaue of x, we have to islolate x
Step1: Subtract 54 from both sides
18x = 180 - 54
18x = 126
Step2: Divide both sides by 18
x = 126/18
x = 7

Solve using the Elimination Method
5x + y = 4
6x - y = 7
Answer:
x=1,y=-1
Step-by-step explanation:
To use the elimination method, we make the coefficient of y the same:
But they are already the same just with different signs.
So we add the 2 equations to make equation 3:
5x + y = 4
+ + = +
6x - y = 7
11x = 11
Solve for x:
x = 1
Substitute the value of x into either equation 1 or 2 to find y:
I chose 1:
5(1)+y=4
5+y=4
y=4-5
y=-1
Our answer is x=1,y=-1
Substituting these values into equation 2 verifies our answer

Step-by-step explanation:
**As you haven't specified if the interest is simple or compounding, I have provided both**
Simple interest[tex]\sf Formula:A = P(1 + rt)[/tex]
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:
P = 5000r = 3% = 0.03t = 2Substituting the given values into the formula and solving for A:
[tex]\implies \sf A = 5000(1 + 0.03 \cdot 2)[/tex]
[tex]\implies \sf A = 5000(1.06)[/tex]
[tex]\implies \sf A = 5300[/tex]
Compound interest[tex]\sf Formula:A=P(1+\frac{r}{n})^{nt}[/tex]

A = final amountP = principalr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = 5000r = 3% = 0.03n = 1t = 2Substituting the given values into the formula and solving for A:
[tex]\implies \sf A=5000(1+\frac{0.03}{1})^2[/tex]
