A school had a girl:boy ratio 5.4.
Ilya [14]

Answer:

164

The 982 part seems wrong. Are you sure it isn't 981?

around 436 if I use 981 instead. 982 would give a decimal and that would be kinda weird for a part human.

Step-by-step explanation:

You can divide the 205 by 5 to simplify the ratio down. 205/5 = 41. Then you can multiply by 4 to find then number of boys.

981

So you can add the 5 and 4 together to 9 and then divide 981 by 9 to get 109. Then you can multiply by 4 to get 436.

Hope this helps!

A customer went to a garden shop and bought some potting soil for $12.50 and 5 shrubs. The total bill was $62.50. Write and solv
lesya692 [45]

Answer:  Equation:  5x = 62.50 - 12.50    or   x = \frac{62.50-12.50}{5}  

x is the cost of each shrub  x = $10

Step-by-step explanation:  Total bill = $62.50.

Subtract the cost of potting soil for $12.50 to find the cost of just the shrubs.   5x  equals that amount

5x = 62.50 - 12.50

5x = 50   divide both sides by 5  

5x/5 = 50/5

x = 10
