Answer:
168
Step-by-step explanation:
Sum the parts of the ratio, 6 + 7 = 13 parts
Divide the total number of students by 13 to find the value of one part of the ratio.
364 ÷ 13 = 28 ← value of 1 part of the ratio, thus
number of girls = 6 × 28 = 168
The three numbers are 52, 53, 54.
52+53=105 105+54=159
Answer:
Step-by-step explanation:
Let the amount charged is y and number of hours is x.
Then the equations are as below.
<u>Attorney A:</u>
<u>Attorney B:</u>
<u>If the amounts are equal, then:</u>
- 150x + 250 = 175x + 150
- 175x - 150x = 250 - 150
- 25x = 100
- x = 4 hours
For this case we can make the following rule of three:
1 box -------------> 15 paperweights
x -------------------> 1269 paperweights
We clear the value of x.
We have then:
x = (1269/15) * (1)
x = 84.6
Rounding to the nearest whole:
x = 85
Answer:
There will be needed about:
x = 85 boxes
