Answer:

3 and 27

Step-by-step explanation:

<u>Step 1:  Determine which two terms we can use</u>

We have the following numbers to choose from:  3, 14, 27

Adding two numbers to get a multiple of ten means that the number that we come up with needs to be divisible by ten.  For example:  20, 30, 50, 100 are all multiples of ten.

In this example the only one that would add up to create a multiple of ten is 27 and 3 which would give us 30 which is a multiple of 10.

Answer: 3 and 27

During martinez family trip they drove from home to a ski lodge a distance of 45 4/5 miles and then drove an additional 17 4/5 m
Fudgin [204]

Answer: the trip is 127 1/5 miles

Step-by-step explanation:

The distance that the martinez family drove from home to the ski lodge is 45 4/5 miles. Converting 45 4/5 miles to improper fraction, it becomes 229/5 miles.

Then, they drove an additional 17 4/5 miles to there friends house. Converting 17 4/5 miles to improper fraction, it becomes 89/5 miles

This means that the total distance that they drove while going is

229/5 + 89/5 = 318/5 miles

If the family drove the same route back home, then the distance traveled during there trip is

2 × 318/5 = 636/5 miles

Converting to mixed fraction, it becomes

127 1/5 miles

For every girl taking classes at the martial arts school, there are 3 boys who are taking classes at the school. if there are 23
just olya [345]
G = number of girls taking the martial arts classes
and
B = number of boys taking the martial arts classes

We know that for every girl, there are 3 boys.  Therefore, the proportion of girls to boys is:
\frac{G}{B} = \frac{1}{3}

When you simplify this ratio by cross-multiplying you get: 
3G = B
When you think about this, it makes sense because you know that there are 3 times as many boys as there are girls.  Therefore you would need to multiply the number of girls by 3 to equal the number of boys in the class.

We know that there are 236 total people in the class, Therefore we know that:
G + B = 236

You can replace the B in the equation above with your simplified ratio to solve, since both contain the variable B:

G + B = 236
is the same as
G + 3G = 236 ->
4G = 236 ->
G = 59

So there are 59 girls in the class, but you need to figure out the number of boys, not girls.  Therefore, subtract 59 from 236 to get to the final answer:

G + B = 236
59 + B = 236
59 + B - 59 = 236 - 59
B = 177
