8. y = -4
Step-by-step explanation:
2 ( -2y - 6 ) + 10 = -4y + 22 + 6y
-4y - 12 + 10 = -4y + 22 + 6y
-6y = 12 - 10 + 22
-6y = 24
y = -4

Step 2: x = 24 − 8
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Tina's solution?

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.

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
Answers
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].

Answers
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
ummm i got something wrong but try c?

In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=71°, and JH = 2 feet. Find the length of IJ to the nearest tenth of a foot.
Answers
Answer:
IJ is 5.8 ft
Step-by-step explanation:
Here, we want to calculate the length of IJ
to Find IJ, we need the appropriate trigonometric ratio
The trigonometric ratio to use in this case is the one that connects the opposite and the adjacent
from the question, IJ is the opposite
This is the side facing the given angle
HI is the hypotenuse which is the side facing the right-angle
HJ is the third side which is the adjacent
Mathematically;
That is the Tan
Tan 71 = IJ/2
IJ = 2 Tan 71
IJ = 5.8

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answers
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
Solve for x.

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
Answers
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

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?
Answers
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
