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.

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.

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

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!

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
