I can't tell what it wants to say in the first part, but I'll do A and B for you.
Because all triangle angles add to 180 degrees, you know that angle PMU is 180-21+35 which is 124.
So a) is 124 degrees
And for b) you take the straight line and you know its 180 degrees. Knowing that angle UMP adds up to 180 degrees when added to PMU which is 124, then you subtract 180 - 124
So b) is 56 degrees.
Hope this helps
Also I can help you with the first 4 if I can see the question.
The strategy for these is to look at what these problems are telling you.
It says the y-value, so you know that this is a y = equation.
y = what?
y = 2 more than. 4 is two more than 2, right? So saying it's more than is another way of saying "y is 2 + blah blah."
So y = 2 + what? Three times the x-value. What does that mean? 3*X = 3X.
Thus we arrive at the final answer, y = 3x + 2
Answer:
R u in 6th grade cause i can't answer this question
Step-by-step explanation:
C. is the correct answer in this case
Since the problem is requesting the answer in minutes, we are going to convert the speed of Mr. Peter to miles per minutes; to do that, we are going to multiply his speed by the multiplier

:

Now, to find the distance from Boston to Worcester, we are going to use the distance formula:

where

is the distance

is the speed

is the time
We know that the speed of Mr. Peter is

and his time is 30 minutes. Lets replace those values in our formula:


Now, lets concentrate on Mr. Peter clone, Mr. P:
Lets convert the speed of Mr. P to miles per minute:

We also know that they will cover the same distance, 30 miles. Lets replace the values in our formula one more time to find t:




But since Mr. P <span>leaves 5 minutes after Mr. Peters, we need to add those 5 minutes to M. P's time:
</span>

We can conclude that Mr. P will arrive first, 5 minutes before Mr. Peter.
