Answer: Good luck my friend I have no idea
Step-by-step explanation:
Make x the subject of the formula y=2x-3
The questions is basically saying make x isolated.
First add 3 to both sides.
y+3=2x-3+3
y+3=2x
Now divide both sides by 2
(y+3)/2=x
x=(y+3)/2
Done!
Any questions just ask me in the comments.

Answer:
Step-by-step explanation:
a) Volume of small cube box = 8 in³
side³ = 8 = 2³
Side of small box = 2 in
b) Side of larger box = 2 + 6 = 8 in
Volume of larger box = 8*8*8 = 512 in³
c) Number of balls to be shipped in the larger box = Volume of larger box ÷ Volume of smaller box
= 512 ÷ 8
= 64 golf balls

Solve this quadratic equation by completing the square.
x^2 + 6x = 18
Step-by-step explanation:
Use formula
[tex] (\frac{b}{2} ) {}^{2} [/tex]
To add a third new term and factor to find the answer. Example
[tex]x {}^{2} + 6x = 18[/tex]
[tex]( \frac{6}{2} ) {}^{2} [/tex]
Which equal 9. so our equation look like
[tex] {x}^{2} + 6x + 9 = 18 + 9[/tex]
The only number that multiply to 9 and add up to 6 is 3. So we write our equation like this.
[tex](x + 3) {}^{2} = 27[/tex]
Take the sqr root of both sides
[tex]x + 3 = \sqrt{27} [/tex]
Subtract 3 from both sides
[tex]x = \sqrt{27} - 3[/tex]
Since a sqr root of a number can be positive or negative, the answer is
[tex] \sqrt{27} - 3[/tex]
or
[tex] - ( \sqrt{27} ) - 3[/tex]

Name the percent equivalent to 3/4?
Answer:
3/4×100%=75%is the percent equivalent to 3/4
A percent is a value out of 100
Change the fraction
= 3/4 * 25
= 75/100
This fraction represents a percent.
= 75/100
= 75%
solve the equation 4(c-3)-8
what are two ways two start solving this equation? choose both ways.
1.use the distributive property to get 4c-3=8.
2.use the distributive property to get 4c-12=8.
3.add 3 to both sides to get 4c=11.
4.subract 4 from both sides to get c-3=4.
5. divide both sides by 4 to get c-3=2.

The perimeter of a rectangular painting is 280 centimeters. If the length of the painting is 76 centimeters, what is its width?
Answer:
76x2 = 152
280 - 152 = 128
128 ÷ 2 = 64
Answer:
the width is 64cm
Step-by-step explanation:
a rectangle has 4 sides, each set of opposite sides are congruent, perimeter is the distance around an object, so we need to add up all 4 sides and it should equal 280cm, we know one side is 76, so our equation should look as follows:
76 + x + 76 + x = 280
2x + 152 = 280
2x = 128
x=64
you can check the answer but substituting 64 for x and seeing if it comes out to 280
76+64+76+64=280
280=280

The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately .41, .10, .04, and .45, respectively. A single Caucasian is chosen at random from the population. a List the sample space for this experiment. b Make use of the information given above to assign probabilities to each of the simple events. c What is the probability that the person chosen at random has either type A or type AB blood
Answer:
a. S = {A,B,AB,O}
b. P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45
c. 0.45 = 45% probability that the person chosen at random has either type A or type AB blood
Step-by-step explanation:
a List the sample space for this experiment.
All possible blood types(A, B, AB or O). So
S = {A,B,AB,O}
b Make use of the information given above to assign probabilities to each of the simple events.
The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately .41, .10, .04, and .45, respectively.
So
P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45
c What is the probability that the person chosen at random has either type A or type AB blood
P(A) + P(AB) = 0.41 + 0.04 = 0.45
0.45 = 45% probability that the person chosen at random has either type A or type AB blood

What is the value of x?
Answer:
A 20°
Step-by-step explanation:
Explanation:-
Given graph
The corresponding angles are congruent (equal to each other)
(x+60)° = 4 x°
x + 60 = 4x
4x-x = 60
3x =60
x = 20°
The value of x=20°

A total of 584 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
584
Step-by-step explanation:
146 adult tickets were sold.
write out your equation first: x+3x=584
4x=584
x=146
Try it out 146+3(146)=584
It worked. That's the solution.
so lets divide the amount of tickets by 4 because there are 4 parts needed in this situation which equals 146 then we know our answer is 146 because the other three parts go to the kids tickets
(hope this helps can i plz have brainlist :D hehe)
Student claims that he can solve 12 X plus 8Y equals 40 and 4X plus 5Y equals 18 for axing why by adding the first equation into multiple of the second equation he can use the new equation and the first equation to create a new system that has the same solution of the original listing it begins by listing for different equations determine whether the student can use the credit to replace the second equation and create a new system that has the same solution select yes or no for each equation
Answer:
x = 2 and y = 2
Step-by-step explanation:
The given system of equations are :
12x+8y = 40 ...(1)
4x+5y = 18 ....(2)
Multiply equation (2) by 3.
12x+15y = 54 ...(3)
Subtract equation (1) by (3).
12x+15y-(12x+8y) = 54-40
12x+15y-12x-8y = 14
7y = 14
y = 2
Put the value of y in equation (2).
4x+5(2) = 18
4x+10 = 18
4x = 8
x = 2
The solutions of the given equations are x = 2 and y = 2

Jane has just begun her new job as on the sales force of a very competitive company. In a sample of 16 sales calls it was found that she closed the contract for an average value of 108 dollars with a standard deviation of 12 dollars. Company policy requires that new members of the sales force must exceed an average of more than $100 per contract during the trial employment period. Can we conclude that Jane has met this requirement at the significance level of 90%
Answer:
There is significant evidence that Jane has met the requirement.
Step-by-step explanation:
Given that:
μ = 100
μ > 100
Sample size, n = 16
Sample mean, x = 108
Sample standard deviation, s = 12
Level of significance, α = 0.1
Degree of freedom, df = n - 1 = 16 - 1 = 15
Test statistic
T = (x - μ) / s÷sqrt(n)
Tstatistic = (108 - 100) / 12 ÷ sqrt(16)
Tstatistic = 8 / 3
Tstatistic = 2.6667
Using the pvalue calculator :
Tstatistic at 0.1, df = 15 ;
P-value = 0.008799
Since pvalue < α
We reject the Null
The is no significant evidence to conclude that Jane has exceeded an average of more than $100
