What is the combined length of all the buttons longer than 1 inch

muminat

Answer:

$2\frac{1}{2}$ inches

Step-by-step explanation:

The "x" represents the number of buttons.

There are 2 sizes longer than 1 inch:

$1\frac{1}{8}$ in and $1\frac{1}{4}$ in

There are NO 1 1/8 inch buttons

THere are two 1 1/4 inch buttons

Hence the combined length would be:

$1\frac{1}{4}+1\frac{1}{4}=2\frac{2}{4}=2\frac{1}{2}$ inches

The ratio of blue tacks to red tacks on the bulletin board is 3 to 5. There are 50 red tacks. How many blue tacks are on the boa

algol13

3:5=x:50

Therefore 5 ×x = 50

x = 10

Therefore 3 × 10 = 30

therefore 30 blue pens

proof = 30 blue + 50 red= 3+ 5

therefore 80 = 8x
