Answer:
12x-11
Step-by-step explanation:
There is no known solution, but this can be simplified. Add up all of the coefficients(# connected by the variable). Since after 7x is a - , the x following has to be negative. After adding the coefficients, you should have below, 12x. Then, you add up all of your constants.(# w/ no variable). Adding negative and positive, you should get below, -11. Finally, you should of simplified your equation to 12x-11.
Equation:
7x- (x-4)= 6x -7
7x- (x-4)= 6x -7
12x
7x- (x-4)= 6x -7
-11
12x-11

Step-by-step explanation:
The flu is starting to hit Weston. Currently, there are 380 people infected, and that number is growing at a rate of 15% per day. Overall, how many people will have gotten the flu in 7 days? If necessary, round your answer to the nearest whole number.
Answer:
1011 or 1010, depending on how you round. (I got 1011)
Explanation:
we need to calculate 15% of the non-constant x seven times.
x starts as 380.
15%=0.15
15% of x seven times:
380*0.15=57,
380+57=437;
437*0.15= 65.55,
437+65.55= 502.55;
502.55*0.15=75.38,
502.55+75.38=577.93;
577.93*0.15=86.69,
577.93+86.69=664.62;
664.62*0.15=99.69,
664.62+99.69=764.31;
764.31*0.15=114.65,
764.31+114.65=878.96;
878.96*0.15=131.84
878.96+131.84= 1011
10 bags of chips and 8 soda cans cost $15.
5 bags of chips and 5 soda cans cost $8.
How much does a bag of chips cost? How much does a can of soda cost?
Answer:
One bag of chips costs $1.10
One can of soda costs $0.50
Step-by-step explanation:
1. Create a system of equations (b = bags of chips | s = soda)
10b + 8b = 15
5b + 5s = 8
2. Use the Elimination method by multiplying 5b+5s=8 by -2
10b + 8b = 15
-2(5b + 5s = 8)
=
10b + 8b = 15
- 10b - 10s = -16
(10b and -10b will cancel out, so you will only have s left)
=
-2s = -1
Divide by 2
Soda = 1/2, or $0.50
3. Plug in S (0.50) into an equation above and get B by itself
5b + 5(0.50) = 8
=
5b + 2.5 = 8
- 2.5 -2.5
5b = 5.5
Bag of Chips = $1.10

Hence, Account A will be the best for Natasha.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, The minimum balance for the account is $500 and the rate of interest is 0.2% in the type A account. She has a saving account so the overdraw fee for her will be $0.
The ATM usage fee for account A is $0 and for other account types, the fee is charged as $3 or $2.50 per transaction.
The online bill payment service is free and $100 is required for opening the account the major advantage of this account is that the check-writing is unlimited.
Therefore, Option a. Account A is the best.

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long. Each president's picture is 6 inches wide. If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?
Answer:
8 pictures
Step-by-step explanation:
Given
[tex]Window = 5\frac{3}{4}ft[/tex]
[tex]Wall = 9.75ft[/tex]
[tex]Pictures = 6\ inches[/tex]
Required
Determine the number of pictures
First, we need to calculate the length of the available space
This is calculated by subtracting the width of the window from the width of the wall.
[tex]Space = Wall - Window[/tex]
[tex]Space = 9.75 - 5\frac{3}{4}[/tex]
Convert fraction to decimal
[tex]Space = 9.75 - 5.75[/tex]
[tex]Space = 4ft[/tex]
Since, the pictures are placed side by side.
This means that, there's no empty space between them.
Number of pictures is:
[tex]Number = \frac{Space}{Pictures}[/tex]
[tex]Number = \frac{4\ ft}{6\ in}[/tex]
Convert feet to inches
[tex]Number = \frac{4 * 12\ in}{6\ in}[/tex]
[tex]Number = \frac{48\ in}{6\ in}[/tex]
[tex]Number = \frac{48}{6}[/tex]
[tex]Number = 8[/tex]
Hence, 8 pictures can fit the wall
Answer:
8 pictures

Callie solved this one-variable equation. When she was done, she tried to verify her answer, but found that it was wrong. Can you find her mistake? 1 2 (4k + 8) = 10 1. 2k + 16 = 10 2. 2k = −6 3. k = −3 What was Callie’s mistake? Callie should have added 10 to both sides in step 2. In step 1, when Callie distributed the One-half to the 8, she multiplied incorrectly. Callie divided by 2 instead of multiplying by 2 in step 3. Callie should have added 16 to both sides in step 2.

What is the approximate length, in centimeters, of the diagonal from point A to point B in the right rectangular prism shown? Round your answer to the nearest whole centimeter.
A.8
B.9
C.10
D.11
Answer:
11
Step-by-step explanation:
First, find the diagonal along the base of the prism. Let B be the diagonal along the base.
8^(2)+6^(2)=b^(2)
64+36=b^(2)
100=b^(2)
10=b
Then let d be the diagonal from point A to point B
b^(2)+5^(2)=d^(2)
10^(2)+5^(2)=d^(2)
100+25=d^(2)
125=d^(2)
\sqrt(125)=d
11=d

One gallon is equal to about 3.785 liters. What is this amount rounded to the nearest tenth? To the nearest hundredth? Show your work. ook at problem 3. What is the greatest number of whole liters of water you could pour into a one-gallon container without it overflowing? Explain your answer.
Answer:
3.8 ; 3.79 ; 3
Step-by-step explanation:
Given that:
1 gallon is equal to about 3.785 litres
3.785 to the nearest tenth :
Tenth digit = 7 ; round up 8 to 1 and add to 7
Hence,
3.785 = 3.8 (nearest tenth)
3.785 to the nearest hundredth :
Hundredth digit = 8 ; round up next digit 5 to 1 and add to 8
3.785 = 3.79 ( nearest hundredth)
What is the greatest number of whole liters of water you could pour into a one-gallon container without it overflowing?
The greatest Number of whole liters of water that could be poured into a 1 gallon container without it overflowing is 3 liters because, rounding up 3.785 to the nearest integer of 4 means we will exceed the maximum litres by about 0.215 gallons and hence, cause the container to overflow.

Answer:
B. 7/9 and 0.7
Step-by-step explanation:
Since 7 is inside the box that means 7 is being divided by 9 so 7/9, which eliminates C and D.
Since there are infinite more 0s in 7.000, there will be infinitely more 7s when you continue to try and divide. which means there must be a little line above the 7 in the 0.7, so the answer is B
