how is 3n+3 is divisible by 3
Answers
Answer:
n + 1
Step-by-step explanation:
Consider the division in fractional form, that is
\(\frac{3n+3}{3}\) ← factor out 3 from each term on the numerator
= \(\frac{3(n+1)}{3}\) ← cancel common factor 3 on numerator/ denominator, leaving
= n + 1

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.

Answers
Answer:

Step-by-step explanation:
D. 3 3/4 is your answer.
Answer:
D. :)
Step-by-step explanation:
So you can do the keep, change, flip method to help.
So first, you keep the 4 11/16 or 75/16. Then, you change the division to mutilpation and then lastly you flip the 1 1/14 or 5/4 to 4/5.
So then the problem is 75/16 x 4/5. So, first you do 75 x 4 to get 300, then you do 16 times 5 to get 80. So now the problem would be 300/80.
So, now you divide 300 by 80 to get 3.75. And if you know, 3.75 is equal to 3 3/4.

A box containing 3 oranges, 2 apples, and one banana weighs 15 units. Another box containing 5 oranges, 7 apples, and 2 bananas weighs 44 units. A third box containing 1 orange, 3 apples, and 5 bananas weighs 26 units. How much does each fruit weigh?
Answers
let x be the weight of oranges
let y be the weight of apples
let z be the weight of banana
3x+2y+z= 15
5x+7y+2z = 44
x+3y+5z=26
solve the three equations
x= 1 unit (orange)
y = 5 unit (apple)

The answer is 8 so its a direct proportion
I think...
The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

The hypotenuse of a right triangle is 50 mm. One leg of the right triangle is 30 mm. What is the length of the other leg? (4 points)
Select one:
a. 20 mm
b. 30 mm
c. 40 mm
d. 60 mm
Answers
The answer is c.
Answer:
C. 40mm
Step-by-step explanation:
To solve for leg a:
Since the hypotenuse is 50mm and leg a is 30mm we can use the following formula below.
a = \(\sqrt{c^2-b^2}\)
\(c^{2}\) will be \(50^{2}\) because c = hypotenuse
\(b^{2}\) will be \(30^{2}\) because b = leg b
Now that we have replaced our variables we can answer the equation:
\(a =\sqrt{50^2-30^2}\)
50 × 50 = 2500
30 × 30 = 900
Now we subtract:
\(a = \sqrt{2500-900}\)
\(a = \sqrt{1600}\)
square root of 1600 = 40
a = 40
Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

sorry I have no clue I don't like mathe either the half of the reason I can't answer it
The expression of length in terms of width is L = 10W and the length of the pan when the width is 7 feet will be 70 feet.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
Suppose, the length and width of the pan are L and W corresponding.
As per the given,
(a)
The length of the pan was ten times its width.
L = 10W
The above expression is the length of the pan in terms of width.
(b)
The lasagna measured 7 feet wide.
L = 10 x 7 = 70 feet
Hence "According to the formula L = 10W, the length of the pan will be 70 feet when the width is 7 feet.".

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
Reasoning Joanne cannot decide which of two washing machines to buy. The selling price of each is $440. The first is
marked down by 30%. The second is marked down by 20% with an additional 10% off. Find the sale price of each washing
machine. Use pencil and paper. Explain why Joanne should buy the first washing machine rather than the second if the
machines are the same except for the selling price.
The sale price of the first washing machine is $
(Round to the nearest dollar as needed.)
Answers
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:
x=$495*0.7=$346.50=$347
The second washing machine:
- is marked down by 20% with an additional 10% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
Y=$495*0.8=$396
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
Z=$396*0.9=$356.40=$356
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: the price of the first washing machine is $347 and the price of the second washing machine is $356. Then compare them 347 O 356
It would be < because the sale price of the machine is more.
Step-by-step explanation: The first machine is marked down(in price) by 30% so 440-100 ($440 is = to 100 because its saying the price is 100% no mark downs or anything. Then you find the price is $347 since it has a 30% mark down.
The second machine is marked down by 20% with an extra 10% off, so 440-100 (100% in price) now you find how much that turns into, and it turns into $356
so the first machine is this better one and cheaper one.

Step-by-step explanation:
Multiply 11 by 7.
Answer:
\(w\geq 77\)
Step-by-step explanation:
How would you get w by itself so that it makes it simplify?
Either you Multiply/Divide and Subtract/Add.
In your case you have \(\frac{w}{7} \geq 11\)
To get w by itself you multiply 7 to both side leaving w.
\(7*\frac{w}{7}\geq 11*7\)
Seven cancel out on the left side leaving w.
11 * 7 = 77.
\(w\geq 77\)
