Answer:
y=-38
Step-by-step explanation:
Undo the things that are being done to the variable.
1: Multiply both sides by nine to undo division.
-45=y-7
2: Add 7 to both side to undo the subtraction.
-38=y
Thats your answer!
Answer:
the answer should be -38 which is option c.
Step-by-step explanation: To get the answer first of all try a number that could be -7 -7 which would be -14 dividing by 9 making the results to be -1.55 or -1.56. So using the same steps trying to find the other answers what is the value of y and if you want use the process of elimination choosing an answer to eliminate and a reason why to eliminate it making it to option c which is the correct answer so sorry if i answer late and please give brainliest to the other people that answer first.

∠ADC and ∠CDJ are complementary angles. What is the m∠ADC?
*Hint, first find the value of x, then find the measure of the angle.
Line A K and line M J intersect at a right angle at point D. Line L C also passes through point D, forming angle A D C and angle J D C. Angle A D C measures four x degrees, and angle J D C measures three x minus eight degrees.
Question 6 options:
90°
56°
14°
34°
∠CDJ = 34°.
Step-by-step explanation:
In this question AK and MJ intersect at 90°.
∠ADC = 4x° and ∠JDC = (3x - 8)°
We have to find the measurement of ∠CDJ.
Since ∠MDA = ∠KDJ = ∠ADJ = ∠MDK = 90°
Therefore ∠ADJ = ∠ADC + ∠JDC = 90°
4x + 3x - 8 = 90
7x - 8 = 90
7x = 98
x = 98/7 = 14
Therefore m∠CDJ = 3x - 8 = 3×14 - 8 = 42 - 8 = 34°
Answer is m∠CDJ = 34°

Answer:
105
Step-by-step explanation:
Area of a trapezoid is given by the formula:
A = (a+b)÷2×h
(where h is the vertical height, and a and b are the parallel lines)
Substituting values given gives us:
A = (6+15)÷2×10
A = 21÷2×10
A = 10.5×10
A = 105
Units will be m² as this is area.

What is the interquartile range of this data set?
Answer:
13
Step-by-step explanation:
To find the interquartile range you would first have to find the median. If you list the number in least to greatest order you will find that the median is 30.5. After you find the median you will spilt the data set up. So on one side it will be 20, 25, 30 and 30, the other side you be 31, 40, 41, and 49. Next, you would find the median of the first set that I listed which is 27.5. You would do the same for the second set and find the median which is 40.5. You would then subtract the first sets median from the second sets median which is 40.5-27.5 and that is 13.

Gas Tank- 11 in , 1.25 ft, 1.75 ft
The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in^3
Current price = 3.79
Answer:
$45.48
Step-by-step explanation:
Given that:
Gas tank are 11 inches, 1.25 feet and 1.75 feet.
The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in³)
Current price = 3.79
Solution:
Formula: Volume = LWH
While,
L = Length
W = Width
H = Height
Since we, know that
Gas tank are 11 inches, 1.25 feet and 1.75 feet.
We have to convert either to inches or feet.
Note that: 1 feet = 12 inches
I will convert feet to inches
Thus,
1.25 × 12 = 15
1.75 × 12 = 21
Since 11 is already in inches we don't have to change that.
Now from the formula: LWH
Therefore, we have:
V = 11 × 15 × 21
V = 3465
Now, from the given the gas tank is 20% full
Finding 20%:
3465 × 20 % = 693
Now subtract to find the other 80%
3465 - 693 = 2772
Since 1 gal = 231 in ³
2772/ 231 = 12
Now, 12 mulitply by the current price of gas given:
12 × 3.79 = 45.48
Hence, the cost to fill the tank is $45.48
Kavinsky
Answer:
$45.48
Step-by-step explanation:
Convert to inches
1.25 × 12 = 15
1.75 × 12 = 21
Since 11 is already in inches we don't have to change that.
Now from the formula: LWH
Therefore, we have:
V = 11 × 15 × 21
V = 3465
Now, from the given the gas tank is 20% full
Finding 20%:
3465 × 20 % = 693
Now subtract to find the other 80%
3465 - 693 = 2772
Since 1 gal = 231 in ³
2772/ 231 = 12
Now, 12 mulitply by the current price of gas given:
12 × 3.79 = 45.48
Hence, the cost to fill the tank is $45.48

Calculations ↓The definition of a fraction is a part of a whole .
If a whole is divided into equal parts, these equal parts are called fractions.
Fractions are written like this :
[tex]\boxed{\\\begin{minipage}{4cm}fractions\\$\displaystyle\frac{x\xrightarrow{numerator}}{y\xrightarrow{denominator}} \\ \end{minipage}}[/tex]
Where
y = the number of total parts
x = the number of parts taken
Now, it doesn't necessarily have to be a pizza or a cake.
Suppose your companion Danette has 32 pencils. Out of them, 8 pencils are red.
What fraction of the pencils is red?
Total number of pencils = 32 (denominator)
Number of red pencils = 8 (numerator)
So the fraction of red pencils is :
[tex]\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{8}{32} \\ \end{minipage}}[/tex]
If the numerator and denominator are divisible by the same number, then we can reduce the fraction :
[tex]\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{1}{4} $\\ \end{minipage}}[/tex]

What is the slope of the line that passes through the points (-7, -2)(−7,−2) and (-15, -14)(−15,−14)? Write your answer in the simplest form.
Answer: The slope is positive, which tells us that the line has an upward direction.
Step-by-step explanation:
The slope of a line is calculated by finding the difference of the y-coordinates and dividing it by the difference of the x-coordinates.
In this case, the difference of the y-coordinates is -2 - (-14) = 12, and the difference of the x-coordinates is -7 - (-15) = 8.
The slope is therefore 12/8 = 1.5.
