3(×+2)=3×-6 I got 0 is that right or wrong
Answer:
Step-by-step explanation:
3(x + 2) = 3x - 6
3x - 6 = 3x - 6
Subtract 6 from both sides of the equation. Then you will get 3x = 3x - 12. Now subtract 3x from both sides of the equation. Leaving you with 0 = -12. So I guess it’s correct?

(w2x−3)÷10⋅z when w=−9, x = 2.7, and z=−25
Enter your answer as a simplified mixed number in the box.
Answer:
-539.25
Step-by-step explanation:
(w^2x−3)÷10⋅z
w=−9, x = 2.7, and z=−25
((-9)^2*2.7−3)÷10⋅(-25)
Parentheses first
The exponent in the parentheses
(81*2.7−3)÷10⋅(-25)
Then multiply
(218.7−3)÷10⋅(-25)
Then subtract
(215.7)÷10⋅(-25)
Now multiply and divide from left to right
21.57*(-25)
-539.25
Answer: It's -1 2/25.

Using the idea that similar triangles are proportional, we can solve this problem fairly easily using a proportion. It is always best to try to draw a picture if possible, as it may increase your understanding of the problem! I have attached an image of the situation.

Select the correct answer. The population of a community, , is modeled by this exponential function, where x represents the number of years since the population started being recorded. p(x) = 2,400(1.025)x What is the approximate population 3 years after the population started being recorded?
A. 7,380 people
B. 2,460 people
C. 2,584 people
D. 14,887 people
The approximate population 3 years after the population started being recorded is 2584 people option (C) is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×
where a is a constant and a>1
It is given that:
The population of a community is modeled by this exponential function, where x represents the number of years since the population started being recorded:
p(x) = 2,400(1.025)×
Plug x = 3 years in the above function.
P(3) = 2400(1.025)³
P(3) = 2400x1.0768
P(3) = 2584.53 ≈ 2584 people
Thus, the approximate population 3 years after the population started being recorded is 2584 people option (C) is correct.

find the product of 3.7 and 0.47
Answer:
[tex]1.739[/tex]
Step-by-step explanation:
We know that [tex]3.7=37/10[/tex].
We also know that [tex]0.47=47/100[/tex].
The product of these is [tex]37/10*47/100=(37*47)/1000=1739/1000=1.739[/tex].
So, the answer is [tex]\boxed{1.739}[/tex]

When 8 is added to the number that is produced by doubling the number x, the result is equal to 8 times the number
that is 5 less than x. What is the value of x? Please help I will give you brainless please
answer:
x=8
Step-by-step explanation:
8+ (2x) = 8*(x-5)
8*(x-5) applies to the distributive law : a(b-c) = ab-ac
a=8 b=x c=5
8x-8*5
8x-40
then add 8+(2x) back into the equation and you have
8+(2x) = 8x-40
subtract 8
2x=8x-48
subtract 8x
-6x=-48
divide by -6
x=8
check work by plugging it in to the provided info-
8*2 = 16
16+8 = 24
8-5 = 3
3*8= 24
x=8

Answer:
2
Step-by-step explanation:
The scaled factor has to be 2 because 4*2=8. You can check 2 is the correct answer by doing 8/2, which is 4. The scaled factor has to be proportional so if one side of ABC was 2 but the same side on ABC prime or A’B’C’ was 10 it would not be proportional, not a scaled factor. Because 2*10 is 5, not 8. But it does not give any other side lengths so it is 4.

Solved ✔︎Nethra was ordering yarn from a discount website. If she ordered more than $50 worth of yarn labeled “discountable,” she could take an extra 10% from the price of that yarn. Only some of the yarn she ordered was eligible for the discount. Here is what Nethra ordered:
2 skeins at $2.50 per skein (not discountable)
8 skeins at $8.40 per skein (discountable)
7 skeins at $5.99 per skein (discountable)

Write the equation of the line that passes through the points (-3, -3) and (8,7).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y + 3 = 10/11(x + 3)
Step-by-step explanation:
Given the points (-3, -3) and (8, 7), we can use these coordinates to solve for the slope of the line using the formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
Let (x1, y1) = (-3, -3)
(x2, y2) = (8, 7)
Substitute these values into the slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - (-3)}{8 - (-3)} = \frac{10}{11}[/tex]
Thus, slope (m) = 10/11.
Next, using the slope (m) = 10/11, and one of the given points (-3, -3), we'll substitute these values into the point-slope form:
y - y1 = m(x - x1)
Let (x1, y1) = (-3, -3)
m = 10/11
y - y1 = m(x - x1)
y - (-3) = 10/11[x - (-3)]
Simplify:
y + 3 = 10/11(x + 3) this is the point-slope form.
