Today 4 friends went out for lunch. Their total bill was $24.80, including tax and gratuity. They decided to split the bill equally and each paid with a $10 bill. How much money will each person get back
Answer:
each person would getb3 dollars back
Step-by-step explanation:
since each friend pays $10 and there are 4 friends the total is 40 but now you have to do $40.00 minus $25.00 because of tax and gratuity so when you do that you get $15.00 now you have to do 15 ÷ 4 and that equals $3.75 and since you cant divide 75 coins to 4 people we dont add that but now you have your answer each friend gets $3.00

PLEASEEE HELP FAST! One solution each is given on four quadratic equations. Assuming that each quadratic equation has two solutions, what is the second solution for each equation?
Answer:
Step-by-step explanation:
If one solution of a quadratic equation is a complex number (a + bi),
Other solution of the equation will be the conjugate of the first solution.
So the other solution will be in the form of (a - bi)
If one solution is, x = -4 - 5i
Other solution will be, x = -4 + 5i
If one solution is, x = 4 + 5i
Other solution will be, x = 4 - 5i
If one solution is, x = 5 - 4i
Other solution will be, x = 5 - 4i

- 1 and 3
Step-by-step explanation:
A certain list contains 11 consecutive multiples of 3.
The first number is 21. What is the middle number?
Answer:
If this set contains an odd number of elements, say, 3, 6 and 9, then median of a set will ... as well as the mean of this set, will equal the mean of the two middle elements. ... the statement (1) says: All members of S are consecutive multiples of 3 ... I think the right answer is C, since 9 + 12 + 15 + 18 + 21 = 75
Step-by-step explanation:
We can't write every number as a sum of consecutive numbers - for example, 2, ... the sum is an odd number, e.g. 1+2=3 2+3=5 3+4=7 4+5=9 5+6=11 6+7=13 ... Some spotted a similar pattern for multiples of 3. ... If you add any 3 consecutive numbers together it will always equal a multiple of 3, e.g. ... 1+2+3+4+5+6=21
Answer:
36
Step-by-step explanation:
11 multiples of 3 starting from 21 - 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51
21 is the first
51 is the last
36 is in the middle

When the teacher asked Henrietta which is bigger 0.8 or 0.64, Henrietta said 0.64 because “it represents 64 of the hundredths, rather than only 8 of them” what do you think of Henriettas explanation?
Answer:
Henrietta is incorrect
Step-by-step explanation:
Start in the tenths place and notice that 8 is greater than 6. This makes 0.8 greater than 0.64
You don't need to consider the hundredths place value unless both numbers in the tenths are the same.
A 33 pound bag of grass seed holds 2 pounds less than 5 smaller bags of seed. Find the weight of the smaller bag of seed.
A 33 pound bag of grass seed has = 2 pounds less than 5 smaller bags of seed
= 33 pounds = 2 pounds less than 5 smaller bags
Let the weight of smaller bag of seed be ' x ' . Then ,
= 33 = 5x - 2
= 5x -2 = 33
= 5x = 33 + 2 ( transposing -2 from LHS to RHS changes -2 into +2 )
= 5x = 35
= x = 35 ÷ 5 ( transposing ×5 from LHS to RHS changes ×5 to ÷5 )
= x = 7 = weight of smaller bag of seed
Then , the weight of smaller bag of seed will be 7 pounds . Let us check it by putting 7 in the place of x :
= ( 5 × 7 ) - 2 = 33
= 35 - 2 = 33
LHS = RHS
Therefore , the weight of of smaller bag of seed is 7 pounds .

What is the equation of this graphed line? If the line passes through (-6,-3) and (6,-7)
Answer:
y= -1/3x - 5
Step-by-step explanation:
Answer:
The answer would be y=-1/3x-7.
Step-by-step explanation:
Using the formula y2-y1/x2-x1 to find the slope of the line, plug in the numbers and you will get a slope of -1/3. Now using the the formula y-y1=m(x-x1) and plug in the numbers, and you will get the equation y=-1/3x-7.
