Answer:
8x+4
Step-by-step explanation:
4(2x+1)=8x+4
X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.
So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.
Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)
That makes 14/6=X/3. When we cross multiply, we find that x=7.
Answer:
18 minutes
Step-by-step explanation:
Sophie can peel all potatoes in 45 minutes, in 1 minute she can peel:
Simon can peel all potatoes in 30 minutes, in 1 minute he can peel:
Together, in 1 minute they can peel:
- 1/45+1/30= 2/90+3/90= 5/90= 1/18 of all the potatoes
To peel all the potatoes they need:
- 1 ÷ 1/18= 1 × 18= 18 minutes
So it will take them 18 minutes to peel all the potatoes
The final amount in the account after 25 years is $24670.42.
<h3>
How do you calculate the final Amount after 25 Years?</h3>
Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.
The final amount in the account is calculated by the formula given below.
Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.
The final amount is given below.
Hence we can conclude that the final amount in the account after 25 years is $24670.42.

the perimeter is:
4(4x - 6)
Applying distributive property:
4(4x) - 4(6)
16x - 24
Then, the perimeter can also be represented by 16x - 24 because 4(4x - 6) can be simplified to 16x - 24
