6.6 = 3(z − 16.9) − –0.6
z =
Answer:
z = 18,9
Step-by-step explanation:
[tex]6.6 = 3(z - 16.9) - - 0.6[/tex]
[tex]6.6 = 3z - 50.7 - ( - 0.6)[/tex]
[tex]6.6 = 3z - 50.7 + 0.6[/tex]
[tex]6.6 = 3z - 50.1[/tex]
[tex]6.6 - 3z = - 50.1[/tex]
[tex] - 3z = - 50.1 - 6.6[/tex]
[tex] - 3z = - 56.7[/tex]
[tex]z = 18.9[/tex]
I need these in slope intercept form
Answer:
y = 5/2 x
Step-by-step explanation:
2m + c = 5
4m + c= 10
__________-
-2m = -5
m = 5/2
c = 0
so, the equation in slope intercept form : y = mx + c
y = 5/2 x + 0
y = 5/2 x
Answer:
y = 5/2 x
Step-by-step explanation:
2m + c = 5
4m + c= 10
__________-
-2m = -5
m = 5/2
c = 0
so, the equation in slope intercept form : y = mx + c
y = 5/2 x + 0
y = 5/2

1/2(f+y)=f-5 as a sentence
Step-by-step explanation:
½(f + y) = f - 5
(f + y)/2 = f - 5
y + f = 2f - 10
y = f - 10
or
f = y + 10

Step-by-step explanation:
total bottles 7/7
4/7 are big,
7/7-4/7=3/7 remaining bottles.
4/5×3/7=12/35 are small.
you add the big bottles and small bottles
4/7+12/35=32/35
then you minus from the total which is 7/7
7/7-32/35=3/35 are tiny.

Answer:
See below.
Step-by-step explanation:
There are 2 options in finding the difference between f and 35, as you did not state in the question which if the 2 is the larger number.
(f-35)-5=f-35-5

Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms? Explain. Sample Response: If there is a variable term and a constant on each side of the equation, then you will need to use the addition or subtraction property of equality once to isolate the variable term and once to isolate the constant. Which did you include in your response? Check all that apply. Use the addition or subtraction property of equality once to isolate the variable term. Use the addition or subtraction property of equality once to isolate the constant.
Answer:
We have to use addition or subtraction property of equality to determine the value of variable involve.
Step-by-step explanation:
Example with variable term:
3x=4-x
Add x on both sides of equation:
3x+x=4-x+x
4x=4
x=1
Example with contact involve:
5y+7=12
Subtract 7 from both sides
5x+7-7=12-7
5x=5
x=5/5
x=1

Find the distance between the two points in simplest radical form (-8,-4) (0,-8).
Answer: Distance = 4√5
Concept:
Here, we need to know the concept of the distance formula.
The distance formula is the formula, which is used to find the distance between any two points.
If you are still confused, please refer to the attachment below for a clear version of the formula.
Solve:
Given information
(x₁, y₁) = (-8, -4)
(x₂, y₂) = (0, -8)
Given equation
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute values into the equation
[tex]Distance=\sqrt{(0+8)^2+(-8+4)^2}[/tex]
Simplify values in the parentheses through addition
[tex]Distance=\sqrt{(8)^2+(-4)^2}[/tex]
Simplify exponents
[tex]Distance=\sqrt{64+16}[/tex]
Simplify by addition
[tex]Distance=\sqrt{80}[/tex]
Simplify the radical value into the simplest form

make a the subject of the formula x²=a²-a²w²
Answer:
a = ± [tex]\sqrt{\frac{x^2}{1-w} }[/tex]
Step-by-step explanation:
Given
x² = a² - a²w ← factor out a² from each term on the right side
x² = a²(1 - w) ← divide both sides by (1 - w)
[tex]\frac{x^2}{1-w}[/tex] = a² ( take the square root of both sides )
± [tex]\sqrt{\frac{x^2}{1-w} }[/tex] = a

Answer:
Step-by-step explanation:
2000 * .125/12 = $20.83
at $100 remaining balance = $1920.81
at $75 remaining balance = $1945.81
The PTA sells 100 tickets for a raffle and puts them in a bowl. They will randomly pull out a ticket for the first prize and then another ticket for the second prize. You have 10 tickets and your friend has 10 tickets. What is the probability that your friend wins the first prize and you win the second prize?
0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.
-----------------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Event A: Your friend wins the first prize.
Event B: You win the second prize.
-----------------------------------
Probability friend wins first prize:
10 out of 100 tickets, so:
[tex]P(A) = \frac{10}{100}[/tex]
-----------------------------------
Probability you win second prize:
There will be 99 tickets remaining(1 has been sorted), you have then of then, so:
[tex]P(B) = \frac{10}{99}[/tex]
-----------------------------------
What is the probability that your friend wins the first prize and you win the second prize?
Multiplication of the probabilities, thus:
[tex]p = P(A) \times P(B) = \frac{10}{100} \times \frac{10}{99} = \frac{10\times10}{100\times99} = 0.0101[/tex]
0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.
