6х + 17 = -7
justify each step
Answers
Answer:
x = -4
Step-by-step explanation:
Subtract 17 on both sides to get 6x = -24 then divide 6 to both sides to get your answer of x = -4
First, you need to get 6x by itself. So you would subtract 17 from both sides. After that you should have 6x= -24.Then you need to get x by itself. You divide 6 from both sides. The answer is x= -4.
Hope this helps!!
Enter the value for x that makes the given equation true.

Answer:
x = -1
Step-by-step explanation:
20x - 5(6x + 4) = 4x - 6
20x - 30x - 20 = 4x - 6
-10x - 20 = 4x - 6
-10x - 4x = -6 + 20

The price of one candle holder before taxes was
Answers
Answer:
$32.00
Step-by-step explanation:
100-36.12 = 67.84 - That's how much she paid for 2 after tax.
So let's eliminate the wrong answers:
63.76*2 is way over 100 so it's not that
33.92*2 is 67.84, but the question asks before taxes so it's not that
32.16*2 is 64.32, but there is tax so we must multiply it by 1.06. 64.32*1.06 is 68.18
32*2 is 64. 64*1.06 is 67.84. There for the correct answer is $32.00

Mr. Donley drove 504 km in each direction on a vacation
trip. The average rate going was 14 km/h faster than the
rate returning. The total time for the entire trip was 21
hours. Find the average rate for each direction.
Answers
Answer:
Data that we know:
He drove 504km in each direction.
Going, the average speed was 14km/h more than returning.
The total trip lasted 21 hours.
Ok, to solve this first:
Let's define the variables:
Sg = Average speed when going.
Sr = Average speed when returning.
Then we can write one of our relationships as:
Sg = Sr + 14km/h.
Now, you can recall the relation:
Time = Distance/speed.
Then we can write the equation that represents the total time of the travel as:
504km/Sg + 504km/Sr = 21h
Now we can replace the Sg by Sr + 14km/h, and get:
504km/(Sr + 14km/h) + 504km/Sr = 21h.
Now we must multiplacate by each denominator, in order to remove them:
504km*Sr + 504km*(Sr + 14km/h) = 21h*Sr*(Sr + 14km/h)
Sr*1008km + 7056km^2/h = 21h*Sr^2 + 294km*Sr
Now we can write a cuadratic equation, where i will ignore the units so it is easier to read, as:
21*Sr^2 -714*Sr - 7056 = 0
The solutions are given by the Bhaskara formula:
[tex]Sr = \frac{714 +- \sqrt{714^2 - 4*21*(-7056)} }{2*21} = \frac{714 +- 1050}{42}[/tex]
We have two solutions, one negative and one positive, and because Sr represents an average speed, it must be a positive number, then we choose the positive solution:
Sr = (714 + 1050)/42 km/h = 42km/h
Now we have the average speed for the returning, with this we can find Sg.
Sg = Sr + 14km/h = 42km/h + 14km/h = 56km/h.

Part C: Using the relation in Part B, what is the value of x if f(x) = 80? (5 points)
(10 points)
Answers
Answer:
A: The data does represent a function because there are no repeating x values. a function can have repeating y values but cannot have repeating x values. Also, there is one value of y for every value of x.
B: f(x)=1/2x
f(x)= 3x-10
f(8)=1/2(8) ----> 4
f(8)=3(8)-10 ----> 14
f(x)=3x-10 has a greater value when x=8
C: f(x)=1/2x
f(x) = 80
80=1/2x
80*2=x
x=160
Step-by-step explanation:
The data in the table is a function. The relation has f(x) = 3x - 10 has greater value when x = 8. And the value of x is 30 when f(x) = 80.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Part A :
The table has the data values,
x : 2 4 6 8
y : 1 2 3 4
The given data represents a function, because elements in the domain (2, 4, 6 and 8) has only one image in the Range (1, 2, 3 and 4).
Part B :
f(x) = 3x - 10
x = 2, then f(x) = y = -4
x = 4, then f(x) = y = 2
x = 6, then f(x) = y = 8
x = 8, then f(x) = y = 14
The relation f(x) = 3x - 10 has the greater value when x = 8.
Part C :
f(x) = 80
3x - 10 = 80
3x = 80 + 10
3x = 90
x = 90 / 3
x = 30
Hence the relation in the table is a function. The second relation f(x) = 3x - 10 has the greater value when x = 10 after computing the values of both the relations.

A- l=p-w
B- l=w-p
C- l=2w-p/2
D- l=p-2w/2

Answer: Choice D
Step-by-step explanation:
p=2w+2l Subtract 2w from both sides
p - 2w = 2w - 2w +2l 2w-2w = 0 cancels
p- 2w = 2l . Divide both sides by 2 2/2 =1 cancels leaving l isolated
p - 2w/2 = l

l = p-2w/2
Dora, the school lunch manager, says that it takes 225 oranges to make 5 gallons of orange juice how many oranges does Dora need to make one gallon?
Answers
Answer:
45
Step-by-step explanation:
Since
5 : 225 = 1 : X
Then we know
225/5 = X/1
Multiplying both sides by 1 cancels on the right
1 × (225/5) = (X/1) × 1
1 × (225/5) = X
Then solving for X
X = 1 × (225/5)
X = 45
Therefore
5 : 225 = 1 : 45
Answer:45
Step-by-step explanation:well all you do is divide 5 from 225
