A man has x matches in a matchbox. On Monday he uses one-quarter of the matches
On Tuesday he uses five more. How many
matches has he used? How many has he left?

Used: 1/4x +5

Left: 3/4x -5

Step-by-step explanation:

Monday: 1/4 of the x matched

1/4x are used

Tuesday: uses 5 more

1/4x +5 are used

Total used 1/4x +5

To find what is left, take what was started with x, and subtract what was used

Left: x - (1/4x+5)

        x - 1/4x -5

         3/4x -5

14

step-by-step explanation:

14 x 3 = 42

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
