Nick is now seven times as old as Harry. In 6 years, Nick will be five times as old as Harry. How old will Harry be in 6 years?If x represents Harry's age now, then which of the following equations could be used to solve the problem?
Answers
In 6 years, Harry is x + 6 , and it is given that Nick's age will be 5(x+6). [t+6]
Combining [t] and [t+6], 7x + 6 = 5(x+6).
So the formula 7x + 6 = 5(x+6) represents the problem.
And x = 12 , so Harry's age in 6 years will be x +6 or 18 years .
I hope this helps!

Step-by-step explanation:
start with 75 cards. Emily did 2/5 of the 75 cards = 30 cards (75 divided by 5 times 2)
75-30=45 cards
Josh signed 1/9 which you have to convert to irregular fraction (45 divided by 9 =5) so 45-5=40 left
Of those left Tatiana completed 20% (40*.20=8)
so 40-8=32

The length of the whole movie was 130 minutes.
Let's call the length of the whole movie "x". According to the problem, Newton and his friends watch 50% of the movie before taking a break. This means they watched 0.5x minutes of the movie.
After the break, they watch the remaining 65 minutes of the movie. So the total time they watched the movie is:
0.5x + 65
But we know that the total time they watched the movie is the same as the length of the whole movie "x". So we can set these two expressions equal to each other and solve for "x":
0.5x + 65 = x
Subtracting 0.5x from both sides, we get:
65 = 0.5x
Dividing both sides by 0.5, we get:
x = 130
Therefore, the length of the whole movie was 130 minutes.

Answer:
We need 2 fluid ounces of the liquid.
Step-by-step explanation:
We have that,
Ratio for the cups and the water = 2 cups : 1 gallon.
It is required to find the number of cups to be added in 1 pint of lemonade.
Since, we know,
1 cup = 8 ounces i.e. 2 cups = 16 ounces
1 pint = 16 ounces
1 gallon = 128 ounces
Thus, we have the relation between ratio of the cups and the liquid as,
i.e.
i.e.
i.e. x = 2
Thus, we need 2 fluid ounces of the liquid.
