B.22x + 11
C.14x + 11
D.18x + 7

Answers

Since you are not distributing at all, you can ignore the parenthesis :)

When ignoring the parenthesis your equation is
18x + 11 - 4x

Then just combine like terms :)

14x + 11

Your answer is C.

Hope this helped!

Adams puts 3/4 of a bag of pens in 3 boxes. If he opens the boxes one by one, how many pens will be in each box

Answers

The number of pens in each bag if Adams puts 3/4 of a bag of pens in 3 boxes is $(1)/(4)$ of a bag.

Given that:

Adams puts a fraction of $(3)/(4)$ of a bag of pens in 3 boxes.

It is required to find the number of pens in each box.

Total number of a fraction of pens available = $(3)/(4)$ of a bag

These pens are equally distributed among 3 boxes.

So, each box will have an equal number of pens.

So, the number of pens in each box is:

$n=(3)/(4) /3$

Take the reciprocal of the second number and the operation becomes multiplication.

$n=(3)/(4) *(1)/(3)$

$=(1)/(4)$

Hence, the number of pens in each box is $(1)/(4)$ of a bag.

Find the difference of -5-(-25)

twice a number plus another number is 310. The difference between the two numbers is 55. What are the two numbers

Answers

t us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
= 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
= 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3

lets say the first number is x and the second y

twice the first number is 2x plus another number (y) =310
the difference of the numbers (x-y) = 55
we have simultaneous equations here:
2x+y=310
x-y=55

to cancel the y's the signs are different so you add the equations to give
3x=365
divide it by 3 to get:
x=121 and 2/3

using the easier equation x-y=55 we know x=121 2/3
now we substitute to get 121 2/3 -y=55
take 121 2/3 from both sides to get:
-y= -66 2/3
therefore y= 66 2/3

that means x=121.6(recurring) and y= 66.6(recurring)
