Answer:
-2/3
Step-by-step explanation:
multiply each side by u +1 to get it out of the denominator
-3(u + 1) = -1
now use distributive property
-3u - 3 = -1
add the 3 to move it over
-3u = 2
now divide by -3
u = -2/3
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.
It would take 110 seconds or a minute and 40 seconds. 400 divided by 50 = 4...... 27.5 multiplied by 4 equals 110; therefore, the answer is mike would swim 400 meters in 110 seconds.
Hello,
There are 24 hours in a day. If 25% of your day is spent at school, then you spent (24)(0.25) = 6 hours at school.
If 8% of your day is spent eating, then you spent (24)(0.08) = 1.92 hours eating.
Together, this is 6 + 1.92 = 7.92 hours ≈ 7.9 hours spent at school and eating in one day.
Hope this helps!
