Answer:
the y-intercept is 8
Step-by-step explanation:
Step 1:seperate all terms away from y
2x+3y=24
3y=-2x+24
step 2:move and divide 3 on both sides.
3y=-2x+24
y=-2/3x+24/3
y=-2/3x+8
So that means the slope is -2/3 and the y-intercept is 8,hope this helps
Answer: C. Twenty-four is 40% of what number
Explanation:
Let the answer in each question is x,
Then in A) What is 40% of 24
In B) What percent is 24 of 40,
In C) Twenty-four is 40% of what number
In D) Forty percent of 24 is what number,
Thus, in problem C the given expression will use.
146/24=6.08333 buses are needed.
But this 0.08333 means that there are 2 students left as a remainder. The first 6 busses are full, and 2 students are remaining outside. We cant leave them there! So we need another bus, which gives a total of 7 buses
Answer:
60mph
Step-by-step explanation:
Speed is the rate of change in distance. Mathematically,
Speed = Distance/Time
Difference in distance between A and B = 285-105miles = 180miles
Total time taken between 2pm and 5pm is 3hours
Speed = 180miles/3hours
Speed = 60miles/hour
Therefore the train speed between the checkpoints is 60miles/hour
Answer:
a = sqrt(33)
Step-by-step explanation:
a^2 + 4^2 = 7^2
a^2 + 16 = 49
a^2 = 33
a = sqrt(33)
