Tina solved an equation incorrectly, as shown below:
Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Tina's solution?
Answer:
Step 2 should be division, not subtraction.

Step-by-step explanation:
Step 1: Define
8x = 24
Step 2: Solve for x
Divide both sides by 8: x = 3We see that 8x is actually 8 times x. Therefore, we would need to use the Division Property of Equality to isolate x and get our answer.
Benny wants to buy a new video game that costs $49.95. He already saved $24.65, and his aunt gave him $15 for mowing her lawn. How much more money does Benny need to buy the video game?
Answer:
$10.30
Step-by-step explanation:
X = 49.95 - (24.65 + 15)
x = 49.95 - 39.65
x = 10.30

Layla opened a savings account and deposited 700.00 as principal the account earns 8%interest compounded annually what is the balance after 6 years
Answer:
The balance after 6 years is $1110.812026
Step-by-step explanation:
The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where
A is the new amountP is the initial amountr is the interest rate in decimaln is the number of periodst is the time in years∵ Layla opened a savings account and deposited $700.00 as principal.
∴ P = 700
∵ The account earns 8% interest compounded annually
∴ r = 8% = 8 ÷ 100 = 0.08
∴ n = 1 ⇒ compounded annually
∵ The time is 6 years
∴ t = 6
→ Substitute these values in the rule above
∵ A = 700[tex](1+\frac{0.08}{1})^{1(6)}[/tex]
∴ A = 700[tex](1.08)^{6}[/tex]
∴ A = 1110.812026
∴ The balance after 6 years is $1110.812026

Izinho do Shanghai Financial Center, o Jin Mao Tower é um imponente arranha-céu inaugurado em 1999. Com 88 andares (referência ao número oito, símbolo de sorte e prosperidade na cultura chinesa) e uma altura de 420 m, a torre tem um shopping, discotecas, bares, cafés, restaurantes, escritórios e o hotel Grand Hyatt. Suponha que uma réplica do Jin Mao Tower seja construída na razão de 1:80 e colocada em exposição no chão de um salão de 9 m de altura. A distância entre o topo dessa réplica e o teto desse salão será de
Answer:
[tex]3.75\ \text{m}[/tex]
Step-by-step explanation:
A escala da réplica é [tex]1:80[/tex]. Isso significa que 1 metro da réplica da escala representa 80 metros do edifício real.
Portanto, 1 metro do edifício real representa [tex]\dfrac{1}{80}[/tex] metros da réplica.
Precisamos encontrar a altura da réplica
[tex]420\ \text{m}=420\times\dfrac{1}{80}=5.25\ \text{m}[/tex]
Assim, a réplica da escala terá uma altura 5.25 m.
Está colocado numa sala com 9 m de altura.
A distância entre o topo da réplica e o teto do corredor é [tex]9-5.25=3.75\ \text{m}[/tex].

A school has 109 students signed up for a science workshop. The school will buy every student attending the workshop a pencil, a folder, and an eraser. A package of 12 erasers is $0.75. Only whole packages of erasers can be bought. Folders are $0.10 each. A package of 8 pencils is $0.50. Only whole packages of pencils can be bought. How much will the school spend?
Answer:
The amount is $25.4
Step-by-step explanation:
There are 109 students to attend the science workshop.
Number of erasers needed is 109, but whole packages of erases can be bought which consist 12 erasers. The total packages of erasers needed would be 10.
The cost of 10 packages of erasers = $0.75 x 10
= $7.5
The cost of 109 folders = 109 x $0.10
= $10.9
Number of pencils needed is 109, but whole packages of pencils can be bought which consist 8 pencils. The total packages of pencils needed would be 14.
The cost of 14 packages of pencils = $0.50 x 14
= $7.0
Total cost = $7.5 + $10.9 + $7.0
= $25.4
The amount that would be spent by the school is $25.4

25.4

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answer:
The average rate of change on the given interval is 9/70
Step-by-step explanation:
Here, we are to find the average rate of change of the function on the given interval
We proceed as follows;
on an interval [a,b] , we can find the average rate of change using the formula;
f(b) - f(a)/b-a
From the question;
a = 0
b = 3
f(0) = -3/5
f(3) = -3/14
Substituting the values, we have;
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70

3. No, I am not using my resources very efficiently. This is because when we need to make more hiking boots you have to make fewer running shoes.
4. I would recommend for them to focus on the hiking boots more because they use less material to make them.
hope this is correct c:
Yes, my resources are being used efficiently if I choose point D, as then I will be making equal amounts of product (1 to 1 ratio).
What is a statistics?
'Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.'
According to the given problem,
This is the most efficient point by far compared to the others, because the two axes are the closest together out of all of the 7 points.
I would recommend that the Shoe Hut focus on both of them, as they have a perfect 1 to 1 ratio.
However, if needed, it is possible to allocate all production power towards running shoe insoles at a 15 to 0 ratio compared to hiking shoe insoles at10 to 0.
Hence, we concluded that, It would be better for the shoe hut to focus on running shoe insoles because they are easier to produce and there is less production of cost.

Answer:
b
Step-by-step explanation:
Answer:
A. Sugar was central to people’s daily lives, work, and economy.
Step-by-step explanation:
Slavery was abolished in the British Empire in 1833, thirty years before the Emancipation Proclamation in the United States. But even after they freed their slaves, the sugar plantation owners were desperate to find cheap labor to cut cane and process sugar. So the British owners looked to another part of the empire—India—and recruited thousands of men and women, who were given five-year contracts and a passage back.
so that means
My great-grandparents had come from India to Guyana—then British Guiana—in the late nineteenth century to work on the sugar plantations. Sugar was the backbone of the British Empire at that time. The demand was huge, for sugar had gone from being a luxury that only kings could afford to a necessity. Even the poorest of London shopgirls took sugar in their tea.

A line is parallel to y = -3x + 2 and intersects the point (4,3). What is the equation of this parallel line?
y = [?]x + [ ]

Parallel lines have the same slope so they can therefore never touch. Just change the y-int. (Any number as long as it's not the same as the previous)

help again! algebra 1
Answer: maybe c?
Step-by-step explanation:
from eqn. 1
3x + 2y = 23
2y = 23 - 3x
y = 23/2 - 3/2x
sub into eqn. 2
1/2x - 4 = 23/2 - 3/2x
1/2x + 3/2x = 23/2 + 4/1
2x = 23/2 + 8/2
2x = 31/2
x = 31/4
sub into eqn. 1
31/4 + 2y = 23
2y = 23 - 31/4
2y = 92/4 - 31/4
2y = 61/4
y = 61/8 or 7 5/8
