Which equation is correctly rewritten to solve for y?
12y + d = –19y + t
A. Y= t+d/-7
B. Y= -7(t+d)
C. Y= t-d/31
D. Y= 31(t-d)
Answers
Answer:
C. y=(t-d)/31
Step-by-step explanation:
Step 1: Add 19y to both sides.
31y+d=t
Step 2: Add -d to both sides.
31y=t-d
Step 3: Divide both sides by 31.
y=(t-d)/31

Help Please 100 point's + Brainly.est 8th grade Math Look at the photos below and answer them PLEASE
Answers
Part 1.
A is.
45 and 34 wood pieces left
B is.
It takes 11 cause 100-89=11 and 11+89=100 and it keeps subtracting 11.
C is.
I dont understand the question(sorry)
D is.
At least 9 shelves,
100-11=89
89-11=78
78-11=67
67-11=56
56-11=45
45-11=34
34-11=23
23-11=12
12-11=1
And you would have 1 wood piece remaining!!
Part one
A. After you build 5 you get 45 pieces, then after you build 6 you get 34.
B. It takes 11 pieces of wood to build each shelf
C. It is negative since y is decreasing in value, while x increases
D. you can build nine shelves
Not sure if there is a specific method you need to use, but you can just do 100 divided by 11 to get 9 remainder something, but you can only build full shelves.
Part 2
A. It took 20 minutes to set up building materials, since the line starts at the y-intercept at (0,20)
B. It takes 25 minutes to build each shelf, since the graph shows that after the first shelf there was a twenty five minute increase from 20 to 45
C. If you work at a constant rate it will take 225 minutes to build nine shelves, you can do this by either multiplying 9 by 25 or continuing the line on the graph.
D. You spent 320 minutes preparing and building 12 shelves. Since we already know it takes 20 minutes to prepare, you just need to multiply 12 by 25 to get 300, then you add them together to get 320.
E. This line represents the amount of time it takes to build shelves
Question 2
A.the initial deposit was $95
B. The line would represent the decrease of money in your account, caused by the maintenance fee.
C. The line will be negative since the y outputs decrease by 6.5
D. The monthly maintenance fee is $6.5, you know this by looking at the difference in outputs
E. After sixth months in total, the remaining balance is $56, you multiply 6.5 by 6 months to get 39, then subtract that from 95.
F. Your balance will be negative after 15 months, just divide 95 by 6.5 then round the answer up

Answer:
No, it does not represent a proportional relationship.
Step-by-step explanation:
The ratios do not reduce to the same value.
40/1 = 40
50/2 = 25
60/3 = 20
We can also tell straight away that this is not a proportional relationship because Nina starts with $30. If the data were graphed, this would mean that the line would not go through the origin. It would start at 30 on the y axis.
Find the missing values in the ratio table. Then write the equivalent

Use the conversions given below to change 153 cm into feet.
Give your answer rounded to 1 dp.
1 inch = 2.54 cm
1 foot = 12 inches
Dont give ridicuous pls
Answers
Answer:
4 feet, 5.1 inches
Step-by-step explanation:
Answer:
Step-by-step explanation:
1 inch = 2.54 cm
x = 153 cm
1/x = 2.54/153 Cross Multiply
2.54x = 153 Divide by 2.54
x = 153/2.54
x = 60.236 inches.
12 inch = 1 foot
60.236 inches = x
12/60.236 = 1/x
12x = 60.236
x = 60.236/12
x = 5.02 feet
To one decimal point this is 5.0 feet.

The Lake Smith basketball team had a team picture taken of the players, the coaches, and the trophies from the season. The picture was 4 inches by 6 inches. The team decided to have the picture enlarged to a poster and then enlarged again to a banner measuring 48 inches by 72 inches.
If the scale factor from the picture to the poster is 500%, find the dimensions of the poster.
What scale factor, as a percent, is used to create the banner from the picture?
What percent of the area of the picture is the area of the poster?
Assume you started with the banner and wanted to reduce it to the size of the poster.
What would the scale factor as a percent be?

Answer:
poster dimensions: 20 inches by 30 inchesbanner/picture scale factor: 1200%poster/picture area ratio: 2500%poster/banner reduction ratio: 41.67%Step-by-step explanation:
a) Poster dimensions are 500% of the picture dimensions:
500% · 4 in = 500/100 · 4 in = 5 · 4 in = 20 in
5 · 6 in = 30 in
The poster is 40 in by 30 in.
__
b) The ratio of banner sized to picture size can be found from the ratio of the smaller dimensions:
48 in/(4 in) = 12 = 12 · 100% = 1200%
__
c) The poster/picture area ratio is the square of the scale factor:
poster area/picture area = (500%)^2 = (500/100)^2 = 25
= 25 · 100% = 2500%
__
d) The poster/banner reduction ratio is ...
20 in/48 in = 5/12 ≈ 0.4167 = 0.4167 · 100% = 41.67%
_____
Additional comment
To convert a number or fraction to a percentage, multiply by 100%. To convert a percentage to a number, divide by 100%, or recognize that "%" means "/100". (As above, 500% = 500/100 = 5.)

The y-intercept is 8.
The points (-2,-5) and (8,0) are also on the line.
The points (-5,-2) and (1,10) are also on the line
Answers
Answer: y=mx+b, m=(y2-y1)/(x2-x1), b=y-intercept, value of y when x=0
m=(-8-10)/(-2-1)
m=-18/-3
m=6
y=6x+b, using (1, 10) we can solve for b
10=6(1)+b
10=6+b
4=b so the line is:
y=6x+4
