2y-3k when y=8 and k=6
Answer:
-2
Step-by-step explanation:
2(8) - 3(6)
16 -18 = -2
Answer:
-2
Step-by-step explanation:
If y = 8, then 2y = 8 times two, so 2y = 16
If k = 6 then 3k = 6 times 3, so 3k = 18
16 - 18 = -2
Hope this helps :)

B. 11c – 9d – 3
C. 7c – 7d – 3
D. 7c – 9d + 3
Answer:
Answer:
11c−9d−3
Step-by-step explanation:
9c−8d+2c−6−d+3

Answer:
0.333n + 28 ; 33.3 ; $41.653
Step-by-step explanation:
For the best fit line :
The slope of the graph :
Drawing a right angled triangle at any point on the best fit line :
Gradient = (y2 - y1) / (x2 - x1)
Gradient = (45 - 30) / (50 - 5)
Gradient = 15 / 45
Gradient = 0.333
Intercept :
Where best fit line crosses the y - axis = 28
b = 0.333n + 28
The extra cost of each extra call made made is the slope of the graph :
$0.333 = 33.3 cents
Estimated cost of 41 calls
b = 0.333(41) + 28
b = $41.653
Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.

A circle has an arc whose measure is 80° and whose length is 88. What is the diameter of the circle?
Answer:
length of arc=80/360×2πr
88×360=80×2×22/7×r
31680×7/(80×2×22)=r
r=221760/3520=63

A holiday costs £1900. Work out the price after a 9% discount
Hey there!
The answer to your question is £1729.
To solve this equation, first we find how much is left. 100% - 9% = 91 %. That means that the new price is 91% of the old price. So, we can do 0.91 x 1900, and we get 1729.
Therefore, the new price is £1729.
Hope it helps! Have a great day, and good luck!
A holiday costs £1900.The price after a 9% discount is £1729
For better understanding , check the calcualtion to find out price after discount below.
CalculationA holiday costs £1900. we need to find out the price after a 9% discount
We are given with 9% discount. find out the discount amount from the cost .
Discount amount = original cost * the discount percentage
discount amount
[tex]1900 \cdot 9percent\\\\1900 \cdot \frac{9}{100} \\171[/tex]
Discount amount is £171
Now subtract the discount amount from the original cost
Final cost after discount is

Hailstones form when strong winds support ice particles high in clouds. We can assume that the diameter of a hailstone varies directly with the time the hailstone takes to form. A hailstone with a diameter of 0.75 inches takes about 12 minutes to form. Write an equation that gives the hailstone’s diameter d after t minutes. Then find the diameter of a hailstone that takes 20 minutes to form.
Answer:
the equation y= ax represents direct variation between x and y is said to vary directly with x. the nonzero constant a is called the constant of variation.

21 = 14 + 7x
Answer:
subtract 14 from each side
7=7x
x=1
Step-by-step explanation:
plz brainliest!
The required solution to the equation 21 = 14 + 7x is x = 1.
An equation is a mathematical statement that shows the equality between two expressions. It consists of an equal sign (=) separating the two sides of the equation.
To solve for x, we can first subtract 14 from both sides of the equation:
21 - 14 = 14 + 7x - 14
Simplifying:
7 = 7x
Next, divide both sides of the equation by 7:
7/7 = 7x/7
1 = x
Therefore, the solution to the equation 21 = 14 + 7x is x = 1.
