A weight lifter can bench press 189 kg. How many milligrams (mg) is this?

Inessa [10]

A weight lifter can bench press 189 kg. How many milligrams (mg) is this?

Answer: We know that:

$1kg=1,000,000 mg$

We are given, that a weight lifter can bench press 189 kg

Therefore, a weight lifter can bench press:

$189 \times 1,000,000 mg$

$189,000,000mg$

$18.9 \times 10^{7} mg$

Therefore, $18.9 \times 10^{7} mg$ is equal to the $189 kg$

Jared has some quarters and dimes that total $5.50. If he has 8 more quarters that dimes, how much dimes does Jared have?

MAXImum [283]

Answer: 10 dimes

Solve using system of equations.
q=number of quarters and d=number of dimes
.25q+.10d=5.50 because the total of dimes and quarters is $5.50
8+d=q because there are 8 more quarters than dimes
substitute 8+d for q into the first equation to get .25(8+d)+.10d=5.50
then simplify
2+.35d=5.50
.35d=3.50
d=10 he has 10 dimes
