Answer:
x = 16
Step-by-step explanation:
This is the answer because:
1) First, minus 4 from +4 and 20
+4 - 4 = 0
20 - 4 = 16
2) Now, you are left with x = 16
Therefore, the answer is x = 16. You can also check by adding 16 + 4 which equals to 20. This is how you solve for the variable by using addition property of equality.
Hope this helps! :D

Carol got 3 times as much as Al, and Diane got $100. How much, in dollars, did
Al get?
Answers
Answer:
Al got 150 dollars
Step-by-step explanation:
If we know for certain that Diane receives 100 dollars, than there is 900 left. If Al gets 150, then Bob, getting twice as much, would receive 300, and carol who gets three times as much would get 450. So 450+150+100+300=1000$

What are the x intercepts of the graph of the function below y = x2 - 3x - 28 .
Answers
The x-intercepts of the graph of the function [tex]y = x^2 - 3x - 28[/tex] are x = 7 and x = -4.
To find the x-intercepts of the graph of the function y = [tex]x^2 - 3x - 28[/tex], we need to set y equal to zero and solve for x. The x-intercepts occur when y is equal to zero.
Setting y = 0, we have the equation:
[tex]0 = x^2 - 3x - 28[/tex]
To solve this quadratic equation, we can factor it or use the quadratic formula. Let's use the quadratic formula in this case.
The quadratic formula states that for an equation of the form [tex]ax^2[/tex] + bx + c = 0, the solutions for x can be found using the formula:
x = [tex]ax^2[/tex]
For our equation [tex]0 = x^2 - 3x - 28[/tex], we have a = 1, b = -3, and c = -28. Plugging these values into the quadratic formula, we get:
x =[tex](-(-3) ± √((-3)^2 - 4(1)(-28))) / (2(1))[/tex]
Simplifying further, we have:
x = (3 ± √(9 + 112)) / 2
x = (3 ± √121) / 2
x = (3 ± 11) / 2
This gives us two possible solutions for x:
x1 = (3 + 11) / 2 = 14 / 2 = 7
x2 = (3 - 11) / 2 = -8 / 2 = -4
Therefore, the x-intercepts of the graph of the function y = [tex]x^2 - 3x - 28[/tex]are x = 7 and x = -4.

What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
After the division has been done, the quotient is obtained. This signifies that the quotient is the result of dividing a dividend by a divisor.
It is given that,
0.8÷10=0.04
Because she has to annex zero in the hundredth place in order to divide 0.8 divided by 20. The quotient is thus 0.04
Thus, to divide 0.8 divided by 20 she needs to annex a 0 in the hundredth place. So, the quotient is 0.04, and Carly is correct

Running at a constant rate, 6 machines can produce 100 boxes of chewing gums in 8 hours . How many more minutes is required to complete the same job with 5 such machines ?
Answers
Answer:
96 more minutes are required to complete the same job with 5 such machines
Step-by-step explanation:
Proportions
We know 6 machines produce 100 boxes of chewing gum in 8 hours. For convenience, we'll work in minutes instead of hours.
The time needed for the 6 machines to complete the job is 8*60=480 minutes.
Considering proportions, if 6 machines complete the job in 480 minutes, then ONE machine would need 6*480 = 2880 minutes.
Now consider 5 such machines working. The time needed would reduce by a factor of 5: 2880/5=576 minutes
Now we know 5 machines would take 576 minutes. That is a difference of 576 - 480 = 96 minutes. Thus,
96 more minutes are required to complete the same job with 5 such machines
selling price of a $17,100 truck with a 5% sales tax.
Answers
Answer:
17100 + 855tax = a total price of 17955
Step-by-step explanation:
We are required to find the selling price of a vehicle given the cost price and sales tax.
The selling price of the truck is $17,955
Given:
Cost price = $17,100
Sales tax = 5%
Amount of tax = 5% of $17,10
= 5/100 × 17,100
= 0.05 × 17,100
= $855
Selling price = cost price + amount of tax
= $17,100 + $855
= $17,955
Therefore, the selling price of the truck is $17,955
