Let c and n represent the numbers of pencil and pen boxes, respectively
.. 3c +2n = 6.00
.. 2c +4n = 8.00
You can halve the second equation and subtract it from the first to get
.. (3c +2n) -(c +2n) = 6.00 -4.00
.. 2c = 2.00
.. c = 1.00
Then
.. 1.00 +2n = 4.00 . . . . . half the original second equation with c filled n
.. 2n = 3.00
.. n = 1.50
A box of pencils costs $1.00; a box of pens costs $1.50.
The fraction of the cake that was ron's pieces is 1/5.
<h3>What is the fraction of the cake was ron's pieces?</h3>
Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).
Since Mrs Jones gave 1/5 of a cake to her neighbour, the remaining fraction will be:
= 1 - 1/5
= 4/5
The fraction of the cake that was ron's pieces will be:
= 2/(1+3+4) × 4/5
= 2/8 × 4/5
= 8/40
= 1/5

Answer: -418, 728, 446, -429, 1159, -696
Step-by-step explanation:
1. 
.
2. 
.
3. 
.
4. The sum of 429 and 429 is 
. We need to subtract this from 429, so 
.
5. The sum of 510 and 319 is 
. Subtracting -330, we get 
.
6. Call the unknown number "
". Then 
, so 
. (Think about it.)
Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5
Base of a cube is a square, and in the given figure it's stated that the measure of each side is " x " ft
Therefore it's Area is equal to : -
Now, since it's Area is given as 1/4 ft², let's equate the Areas to find the measure of each side ~
that is ~
It's time to find the volume of cube that is ~
So, let's plug the value of side length (1/2 ft)
Volume is equal to ~
Hence, the required 1/8 or 0.125 ft³
I hope it helped ~
