James wants to send two gifts by mail. one package weighs 2 3/4 pounds. one package weighs 2 3/4 pounds. the other package weighs 1 3/4 pounds. what is the total weigh of the package?

4 1/2 pounds

Step-by-step explanation:

To add 2 3/4 and 1 3/4, first add the whole number portions:

2+1 = 3

Next add the fractions.  These two already have a common denominator, so we just add the numerators:

3/4+3/4 = (3+3)/4 = 6/4

This gives us 3 6/4.  This is a mixed number with an improper fraction; we must simplify.

4 goes into 6 one time with 2 left over; this makes it 1 2/4.  This makes our total

3+1 2/4 = 4 2/4 = 4 1/2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
