Number of text messages Keisha sent: 16

Number of text messages Miguel sent: 21

Number of text messages Pablo sent: 32

Step-by-step explanation:

Total messages sent = 69

Let,

Messages sent by Keisha = x

Messages sent by Miguel = y

Messages sent by Pablo = z

According to given statement;

x+y+z=69    Eqn 1

y=x+5    Eqn 2

z=2x    Eqn 3

Putting Eqn 2 and 3 in Eqn 1

x+(x+5)+2x=69\\x+x+5+2x=69\\4x=69-5\\4x=64

Dividing both sides by 4;

\frac{4x}{4}=\frac{64}{4}\\x=16

Putting x=16 in Eqn 2

y=16+5=21

Putting x=16 in Eqn 3

z=2(16)=32\\

Number of text messages Keisha sent: 16

Number of text messages Miguel sent: 21

Number of text messages Pablo sent: 32

8th grade math, please help

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 y-value is two more than three times the x-value
Nimfa-mama [501]
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

When Mr. Peters drives from Boston to Worcester it takes him 30 minutes travelling at a speed of 60 miles per hour. Mrs. Peters
pochemuha
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 \frac{60min}{1h}:
60 \frac{miles}{h} * \frac{1h}{60min} =1 \frac{mile}{min}

Now, to find the distance from Boston to Worcester, we are going to use the distance formula: d=vt
where
d is the distance
v is the speed
t is the time 

We know that the speed of Mr. Peter is 1 \frac{mile}{min} and his time is 30 minutes. Lets replace those values in our formula:
d=1 \frac{mile}{min} *30min
d=30miles

Now, lets concentrate on Mr. Peter clone, Mr. P:
Lets convert the speed of Mr. P to miles per minute:
\frac{90miles}{h} * \frac{1h}{60min} =1.5 \frac{miles}{min}
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:
d=vt
30miles= 1.5\frac{miles}{min} *t
t= \frac{30miles}{1.5\frac{miles}{min}}
t=20min
But since Mr. P <span>leaves 5 minutes after Mr. Peters, we need to add those 5 minutes to M. P's time:
</span>t=20min+5min
t=25min

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