I think it is b and d .

Hello again! Both D and B are rectangles.
Step-by-step explanation:
You know that a rectangle has 4 sides like a quadrilateral but it is different. Both of the oppiosite sides are the same length. C would not be one because it is not connected therefore it is not a full shape. Because of A´s even sides, A is not a rectangle. I hope this helps! :]

You estimate that the length of your
classroom is 20 feet. The actual length is 25
feet. Find the percent of error.
Answer:
The percent error is 20%.
Step-by-step explanation:
The general formula is to subtract the actual value from the estimated value, take the absolute value of the difference, divide that answer by the actual value, then multiply it by 100.
So, 20 (estimated) minus 25 (actual) is -5. The absolute value of -5 would be 5, since absolute value is always positive. Divide 5 by the actual value, 25, and you get 0.2. Multiply 0.2 by 100 to get a percent value, and the answer will amount to 20%. Hope this helps.

Check by going backwards
Answer:
13 y/o
Step-by-step explanation:
a + b + c )/3 = 9
c-4 = a c = a+4
b+3 = 2/3 ( a +3) b = 2/3( a+3) - 3 Sub the red in to the top equation
(a + 2/3(a+3)-3 + a+4 )/3 = 9
2 2/3 a +3 = 27
8/3 a = 24
a = 9 then c=a+4 = 13 y/o and b=5

2/3x-7=11
Pls help
Answer:
x = 27
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x - 7 = 11 ( multiply through by 3 to clear the fraction )
2x - 21 = 33 ( add 21 to both sides )
2x = 54 ( divide both sides by 2 )
x = 27
The value of x in the equation 2/3x-7 =1 is 12.
The given equation is 2/3x-7 =1.
x is the variable in the equation.
Minus is the operator.
To solve for x add 7 on both sides:
2/3x-7+7=1+7
2/3x=8
Multiply both sides by 3/2.
x=3/2×8
x=12
Hence, the value of x in the equation is 12.

This graph shows the relationship between the pounds of cheese bought at a deli and the total cost, in dollars, for the cheese. Identify the constant of proportionality represented in the graph.
Answer:
y = 4x
Step-by-step explanation:
formula is y=kx, where k is factor of proportionality
Looking at the graph where y and x meet...
2/0.5 = 4 so 2 = 4(0.5)
Therefore, 4 is k (constant)
4=4(1)
6=4(1.5)
10=4(2.5)

Let x represent the number of pounds of lobster sold. Then 25.5-x is the number of pounds of fish. The total money made is ...
4.25(25.5-x) +9.00x = 196.25
4.75x + 108.375 = 196.25 . . . . . simplify
4.75x = 87.875 . . . . . . . . . . . subtract 108.375
x = 18.5 . . . . . . . . . . . . . . . divide by 4.75
The market sold 7 pounds of fish and 18.5 pounds of lobster.
