pen costs twice as much as a pencil. The total cost of 1 1 pen and 1 1 pencil is $2.10 $ 2 . 10 . If p represents the cost of 1
dybincka [34]

Answer : The equation could you use to find p is, 2p+p=2.10

Step-by-step explanation :

Let the cost of 1 pen be, 'x'

and the cost of 1 pencil is, 'p'

As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:

x+p=2.10    ............(1)

And we have also given that the pen costs twice as much as a pencil. The equation will be:

x=2p    ............(2)

Now put the equation 2 in equation 1, we get:

x+p=2.10

2p+p=2.10

Thus, the equation could you use to find p is, 2p+p=2.10

7. Simplify this what’s the answer?
trasher [3.6K]

first the square root of 4 is 2 so we can sub that in.

now we have 2(2*2)^-2.

2 * 2 of course is 4

with 2(4)^-2, keep in mind that negative exponents just mean to "flip" the number and turn the exponents positive.

so 4^-2 is the same as 1/4^2 or 1/16.

finally 1/16 * 2 = 2/16. 2/16 simplified is 1/8.

You want to put $2,500 in a simple interest account.It has a 4% annual interest rate.How long will it take you to earn $200 in i
prohojiy [21]
It will take 2 years.

Year 1 :
4% 2.5k = 2.5k/100 × 4 = $100 in interest

$2.5k + $0.1k = $2.6k

Year 2 :
4% 2.6k = 2.6k/100 × 4 = $104 in interest

$100 + $104 = $204 > $200

There may be a simpler way to solve this using a formula for example, but I just solved this step by step. Please feel free to ask if you have any questions
