I have 3 1/2 bottles of maple syrup. I filled nine one quart bottles with syrup. How much syrup do I have left?
Answers

Total amount of syrup [tex]= \frac{31}{2}[/tex]
Bottles filled with syrup [tex]= 9\frac{1}{4}[/tex]
Syrup left
[tex]= \frac{31}{2} - 9\frac{1}{4}\\= \frac{31}{2} - \frac{37}{4}\\= \frac{62-37}{4}\\= \frac{25}{4}[/tex]

What is the value of q in the solution to this system of equations?
2m - 5q= 8
4m + 2q = 64
Answers
Answer: I’m guessing 9
Step-by-step explanation:
fvccckkk school lol
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
2m - 5q = 8
4m + 2q = 64
The value of q in the solution to the equations is 4.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2X = 4 is an equation.
We have,
2m - 5q = 8 ____(1)
4m + 2q = 64 _____(2)
From (1) we get,
2m = 8 + 5q
Divide both sides by 2.
m = (8 + 5q)/2 ______(3)
Now,
Putting (3) in (2) we get,
4m + 2q = 64
4/2 (8 + 5q) + 2q = 64
2 (8 + 5q) + 2q = 64
16 + 10q + 2q = 64
16 + 12q = 64
12q = 64 - 16
q = 48/12
q = 4
Now,
q = 4 in (3) we get,
m = (8 + 5q) / 2
m = (8 + 5 x 4) / 2
m = (8 + 20) / 2
m = 28 / 2
m = 14
Thus,
The value of q in the solution to the equations is 4.

PLEASE HELP DUE IN 5 MIN... Carson has a smart phone data plan that costs $40 per month that includes 2 GB of data, but will charge an extra $10 per GB over the included amount. How much would Carson have to pay in a month where he used 3 GB over the limit? How much would Carson have to pay in a month where he used went over by xx GB?
Answers
Answer:
a. $70
b. $(40 + 10x)
Step-by-step explanation:
The standard cost of the charges is $40 per month but an extra $10 per GB over the included amount.
a. Firstly the cost for a month in which he uses 3GB over the limit
we have a standard of $40, then he has to pay $10 per GB for the 3GB over the limit.
Thus the cost of the 3GB is $10 * 3 = $30
The total cost for using 3GB above the limit would be $40 + $30 = $70
b. For using x GB above the limit
He has to pay $10 per each GB above the limit
Thus, the amount to be paid for x GB above the limit would be x * $10 = $10x
So the total amount to be paid would be the base fee plus over the limit fee= $(40 + 10x)
Suppose Tommy walks from his home at (0, 0) to the mall at (0, 6), and then walks to a movie theater at (7, 6). After leaving the theater Tommy walks to the store at (7, 0) before returning home. If each grid square represents one block, how many blocks does he walk? Blank Tommy walks blocks.
Answers
Answer:26 blocks
Step-by-step explanation:
If his home is at (0,0) and he goes to (0,6) that’s 6 blocks. Then he goes to (7,6) which is only 7 more blocks since he was already at (0,6), so now he’s at 13 blocks. Lastly, if he goes from (7,6) to (7,0) that would add 6 more blocks making it 19 blocks.
However there wasn’t a picture included so i’m not sure if you would also add the blocks it took him to get home again. If they want you to include him getting home again then the answer would be 26 blocks, if not 19 blocks.

Find the 9th term.
Answers
Answer:
The 9th term of the sequence is:
[tex]a_9=\frac{65536}{6561}[/tex]Step-by-step explanation:
Given the sequence
1, 4/3,16/9
computing the ratios of all the adjacent terms
[tex]\frac{\frac{4}{3}}{1}=\frac{4}{3},\:\quad \frac{\frac{16}{9}}{\frac{4}{3}}=\frac{4}{3}[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]r=\frac{4}{3}[/tex]
A geometric sequence has a constant ratio 'r' and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
As
[tex]a_1=1[/tex][tex]r=\frac{4}{3}[/tex]so substituting [tex]a_1=1[/tex] and [tex]r=\frac{4}{3}[/tex] in the nth term of the equation
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=\left(\frac{4}{3}\right)^{n-1}[/tex]
Now, substitute n = 9 to determine the 9th term
[tex]a_9=\left(\frac{4}{3}\right)^{9-1}[/tex]
[tex]a_9=\left(\frac{4}{3}\right)^8[/tex]
[tex]a_9=\frac{4^8}{3^8}[/tex]
[tex]a_9=\frac{65536}{6561}[/tex]
Therefore, the 9th term of the sequence is:

Pls mark brainliest.
Answer:
a = -8
Step-by-step explanation:
4a - 7 = 5a + 1
subtract 1 from both sides of the equation
4a - 7 - 1 = 5a + 1 - 1
4a - 7 - 1 = 5a
4a - 8 = 5a
subtract 4a from both sides of the equation
4a - 4a - 8 = 5a - 4a
-8 = 5a - 4a
-8 = 1a

Answers
Answer:
Step-by-step explanation: Answer:46.21
Step-by-step explanation:t/42.99 = 7.5/100.
Butterfly method
42.99 x 7.5 = 322.42 divided by 100= 3.22 plus 42.99 = 46.21etc
The total cost for the sweatshirt is $46.21.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Ryan wants to buy a sweatshirt for $42.99.
The sale tax rate in his city is 7[tex]\frac{1}{2}[/tex]%.
Converting mixed fraction to improper fraction,
7[tex]\frac{1}{2}[/tex] = 15/2
Let n + 42.99 be the total cost of the sweatshirt.
n = 15/2 x 42.99 / 100
n = 322.425 / 100
n = 3.22
n + 42.99 = 46.21 to the nearest cent.
Therefore, the cost with sales tax is $46.21.
