The pair of numbers that would have 20 as their lcm is 4 and 5
Answer:
a.) 20 kilometers
b.)1.67 hours
Step-by-step explanation:
a.) formula= speed =distance/time
Speed= 10km/hr
Distance=unknown
Time=2hrs
Therefore from formula, distance=speed x time
10 x 2
20 kilometers
b.) If average speed is increased by 2km/hr then
total speed= 2+10=12km/hr
Distance remains constant therefore distance= 20km
Therefore time =distance/speed
20/12
= 1.67 hours
Answer:
x = 2.25
Step-by-step explanation:
-9(x - 5) = x + 22 1/2
Distribute the nine and then add 9x to both sides
-9x + 45 = x +22 1/2
+ 9x + 9x
Then try to get x alone
45 = 10x + 22 1/2
-22 1/2 -22 1/2
22.5 = 10x
2.25 = x
The number of salads Maeve eats per day if she made 15 salads for 3 days is 5 salads eaten per day.
<h3>Unit rate</h3>
Unit rate refers to the number of units of the first type of quantity corresponding to one unit of the second type of quantity.
- Number of salads = 15 salads
- Number of days = 3 days
Unit rate of salad eaten per day = Number of salads ÷ Number of days
= 15 ÷ 3
= 5 salads eaten per day
A salad is a food made primarily of a mixture of raw or cold ingredients, typically vegetables, usually served with a dressing such as vinegar or mayonnaise.
Therefore, the number of salads Maeve eats per day if she made 15 salads for 3 days is 5 salads eaten per day.
