Dora uses a 0.35 meter length of ribbon for each bracelet she makes. She makes 4 bracelets.
How many meters of ribbon does she use? Which of the following grids models the problem?

Dora uses 1.4 meters of ribbons to make four bracelets.

Step-by-step explanation:

The length of ribbon required to make one bracelet is, l = 0.35 m.

The number of bracelets made by Dora is, n = 4.

Compute the total length of ribbons used to make the four bracelets as follows:

Total length of ribbons = length of on bracelet × number of bracelets

Thus, Dora uses 1.4 meters of ribbons to make four bracelets.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
