Answer:
X = 32 meters.
Step-by-step explanation:
- Let the unknown distance be X.
<u>Given the following data;</u>
- Distance = 8 meters per hour
- Time = 4 hours
To find how many meters he would cover in four hours;
1 hour = 8 meters
4 hours = X meters
Cross-multiplying, we have;
X = 8 * 4
<em>X = 32 meters.</em>
X = dull pencils
y = sharp pencils
x + y = 100
y = x + 16 ~~Plug this back into your original x+y equation.
x+x+16=100 ==> 2x = 84 ==> x = 42. Plug this back into the y = equation
y = 42 + 16 ==> y = 58.
42 Dull, 58 sharp.
That means she need to buy 2 packs of 100.
