Answers
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

four times a number x is at least -12
an inequality is ?
the solution is ?
Answers
Answer:
-16
Step-by-step explanation:
im just taking a guess.
x+4>-12
-4 -4
---------------
4's cancel out and -12+-4=-16
Again this is just a guess.
The inequality is 4x ≥ -12 and the solution of this inequality is x ≥ -3.
What are Inequalities?Inequalities are the expressions having two sides connected with inequality symbols. Inequality symbols are <, >, ≤, ≥ and ≠. They may contain one or more variables and constants.
Inequalities which consist of one or more variables with the highest degree of the variables being 1 is called Linear inequalities.
Given that four times a number is at least -12.
Thus the inequality says that 4 multiplied with a number x, which is 4x has values -12 or greater than -12.
So the inequality is 4x ≥ -12.
Solving this,
4x ≥ -12
Dividing both sides by 4, we get,
4x/4 ≥ -12/4
x ≥ -3
Hence the inequality is 4x ≥ -12 and the solution is x ≥ -3.

(MARKING BRAINLIEST) Kareem cannot decide which of two washing machines to buy. The selling price of each is $390. The first is marked down by 40%. The second is marked down by 10% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answers
Answer:
See explanation
Step-by-step explanation:
The selling price is $495.
The first washing machine:
- is marked down by 30%
$495 - 100%
$x - 100% - 30% = 70%
Find the value of x:
The second washing machine:
- is marked down by 20% with an additional 10% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

Answer:
1 3 4
Step-by-step explanation:
umm i suck at explaining sorry
Answer: Multiplying both sides of the equation by 3
substituting 36 for p to check the solution
Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.
Then you have 3(p/3) = 3(12)
p = 36 simplify
To check this work, you can substitute 36 for p:
36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

Jerry has 7 3/4 dozen donuts. He purchased another 4.25 dozen donuts. How many dozens of donuts does he have now?
Answers
Answer:
12 dozen
Step-by-step explanation:
Relatively easy stuff, just recall fractionsA dozen means 12he has 7 dozen (7 x 12=84) and 3/4 dozen (3/4 x 12=9) so that's 84+9= 93 donutshe gets 4.25, which is the same as 4 1/4, so its 4 dozen (4 x 12=48) and 1/4 dozen (1/4 x 12=3) so that's 48+3= 51 donutsAdd what you got 93 + 51 = 144 donutsThen divide this by 12 to get the number of dozens144/12 = 12 dozenAnswer:
12 dozens of donuts
Step-by-step explanation:
First, you want to change the decimal into a fraction. The decimal, 4.25, is the same as 4 25/100. You can reduce 4 25/100 to 4 1/4 by diving both the numerator and denomiator by 25. Now that both of our numbers are fractins, we can just add the fractions up. 7 3/4 + 4 1/4 = 11 4/4 = 12\
Jerry got 12 dozens of donuts.

Consider the two functions below. Which one of these functions is linear? What is its equation? Enter any answers to two decimal places.
Answers
Answer:
Function A and the equation would be y = 1.6666666666~x + 0
Step-by-step explanation:
A linear function is a function that is a straight line with no change so function B does not fit that description. So than it has to be A
To find the equation you first what to find the slope of the line
ΔY/ΔX = 5/3 = 1.666666666666
Take the slope and multiply it by x to get y
Following are the solution to the given function:
Given:
Function A:
[tex]\bold{x} \ 3 \ 6 \ 9 \ 12 \ 15 \\\\\bold{y} \ 5 \ 10 \ 15 \ 20 \ 25[/tex]
To find:
Find the function=?
Solution:
Function A or equation would've been [tex]\bold{y = 1.6666666666 \sim x + 0}[/tex].The linear equation is a straight line with really no modification, hence function B doesn't suit its description. As a result, it has to be A.You must first calculate the slope of the line to solve this equation.[tex]\bold{\to \frac{\Delta Y}{ \Delta X} = 5/3 = 1.666666666666}[/tex]To get y, take the slope then multiply this by x.help and i give brainlliest
