Marguerite is building a box. She needs 78 pieces of wood that are 29 cm long. The wood comes in boards that are 6 meters long.
ser-zykov [4K]
First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:
78*29cm=2262cm

Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:
2262cm* \frac{1m}{100cm} =22.62m

Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:
\frac{22.62m}{6m} =3.77
Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.

We can conclude that <span>Marguerite will need 4 boards of wood.</span>

<span>x - number of nickels .
y -number of dimes.
two equations in two unknowns:

x = 55 - y
0,05</span>·(55 - y) + 0,1y = 3,90<span>2,75 - 0,05y + 0,1y = 3,90
0,05y = 1,15
y = 23.
