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
Answer from: Quest
the 8 in 8,420 is in the thousands place so it's value is 8 thousand.
the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.
divide 8000 by 800 to find the answer:
8000 / 800 = 10
the 8 in 8,420 is 10 times greater than the 8 in 6,870

Which of the following is the equation that says that the product of a number and ten is equal to 20 percent of that number ? a) 10n= 2.0n b) 10+n=.20n c) n+ .20n=10 d) 10n=0.20n
Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
