Answer:
-2
Step-by-step explanation:
An equation is shown below: 3(4x + 5) = 12 Which of the following correctly shows the beginning steps to solve this equation? (4 points) Group of answer choices Step 1: 12x + 15 = 12 Step 2: 12x = −3 Step 1: 12x + 5 = 12 Step 2: 12x = 7 Step 1: 7x + 5 = 12 Step 2: 7x = 7 Step 1: 7x + 8 = 12 Step 2: 7x = 4
Answer:
I believe the answer would be step 1: 12x + 15 = 12, and step 2: 12x = -3.
Step-by-step explanation:
3(4x + 5) = 12, you would foil and do 3 times 4x which is 12x, then do 3 times 5 which is 15. So the result would be 12x + 15 = 12. And the step 2 that goes along with this answer. you would do -15 on both sides of the equal sign, so now you have 12x = 12 - 15 which is -3, so it would be 12x = -3
Answer:
Step 1 would be the answer: Step 1: 12x + 15 = 12 Step 2: 12x = −3 Step 1: 12x + 5 = 12

$8.60
$8.59
$8.69
$8.50
Well, I dont think that amount of money is a real amount so.
But my guess would be $8.60
Explanation:
Since you provided us with 5,9, and 7, you should use the 7 to round up the next number. So, you round the 9, to 10, so you add the 1 from the 10, on the 5. So it is 6. So your answer is $8.60.

there are 84 students in the 8th grade. if they are split evenly into 6 groups how many students will be in each group
Answer:
14
Step-by-step explanation:
First, we must identify what the question is asking.
84 students are being split into 6 groups.
If you have a calculator, you can simply enter "84 / 6".
If not, we must do some long division!

The mean attendance for the first four meetings is 20. Is the number of students who attended greater than, less than, or equal to 20? Explain
Answer:
Greater than 20Step-by-step explanation:
Since mean is the average number of students, the formula for calculating the mean attendance of students is expressed as;
Mean = total number of student/sample size
[tex]\overline x = \frac{\sum Xi}{N}[/tex]
Given mean = 20
Since the question talks about the first four meetings, the sample size = 4
[tex]20 = \frac{\sum Xi}{4}\\ \\\sum Xi = 20 * 4\\\\\sum Xi = 80[/tex]
Since the sum total of students for the first four meetings is 80, hence the number of students who attended the meeting is greater than 20

Listen i know its dumb but-
solve for w
10 + w = -9
Answer:
w = -19
Explanation:
To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.
[tex]10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19[/tex]
If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.
[tex]10 + w = -9\\10 + -19 = -9\\-19 = -19 [true][/tex]
Therefore, the value of w in the given equation is -19.

Answer:
Give M the statement of this question
∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)
∘
and m\angle B=(6x-21)^{\circ}∠B=(6x−21)
∘
, then find the measure of \angle B∠B.
Answer:
∠ B = 15°
Step-by-step explanation:
Complementary angles sum to 90° , that is
∠ A + ∠ B = 90 , substitute values
8x + 27 + 6x - 21 = 90
14x + 6 = 90 ( subtract 6 from both sides )
14x = 84 ( divide both sides by 14 )
x = 6
Thus
∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°

what is the inverse function of
[tex]g(x) = (x + 2) ^{2} + 1[/tex]
Answer:
Im not gonna hand it to you, but heres what you need to solve it. :)
Step-by-step explanation:
An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. We can write this in terms of the composition of f and g as g(f(x))=x.
You bake a batch of muffins. You freeze 6 muffins and share the rest equally among yourself and 2 friends. Write an
expression that can be used to determine the number of muffins, m, each friend gets.
The expression to determine number of muffins each friend gets is ; m = [tex]\frac{x}{3}[/tex] - 2.
It is given that 6 muffins are freeze and rest are equally shared among yourself and 2 friends.
We have to find out the number of muffins each one will get.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
As per the question ;
The number of freeze muffins = 6
The rest of muffins are equally divided between me and 2 other friends.
Let's assume that the total number of muffins is x.
The number of muffins distributed between 2 friends and me is ;
= x - 6
The number of muffins (m) each one will get ;
m = [tex]\frac{x-6}{3}[/tex]
or
m = [tex]\frac{x}{3}[/tex] - [tex]\frac{6}{3}[/tex]
or
m = [tex]\frac{x}{3}[/tex] - 2
Thus , the expression to determine number of muffins each friend gets is ; m = [tex]\frac{x}{3}[/tex] - 2.
