Sorry I had to upload a question
Answer:
420 people in 3 hours. 140 people per hour.
Step-by-step explanation:
this is quite simple
35 p = 15 m
140 p = 1 hour
420 p = 3 hours
for the first part:
Let's solve for x.
−x+3y=14
Step 1: Add -3y to both sides.
−x+3y+−3y=14+−3y
−x=−3y+14
Step 2: Divide both sides by -1.
−x/−1 = −3y+14/−1
x=3y−14
Answer:
x=3y−14
Second part:Let's solve for x.
3x−3y=−6
Step 1: Add 3y to both sides.
3x−3y+3y=−6+3y
3x=3y−6
Step 2: Divide both sides by 3.
3x/3= 3y−6/3x=y−2
Answer:
x=y−2
Hello,
One method of finding a value in between two other numbers is taking the average, it will always be between the numbers. To find the average of two numbers, add the numbers and divide it by how many numbers there are.
In this case, we have:
(0.3) + (0.5) /2 = 0.8 / 2 = 0.4
So, 0.4 is one length that is within the given span.
Another example is 0.45, which is also between 0.3 and 0.5.
0.4 represented as a fraction is 4/10. However, this can be simplified (notice 4 and 10 are both divisible by 2). To simplify this fraction, divide the numerator and denominator of the fraction by 2 to get (4/2) / (10/2) = 2/5.
0.45 represented as a fraction is 45/100. This fraction can also be simplified (notice 45 and 100 are both divisible by 5). To simplify this fraction, divide the numerator and denominator of the fraction by 5 to get (45/5) / (100/5) = 9/20.
Two lengths that are within the span are 2/5 inches and 9/20 inches, both of which are in simplest form.
Hope this helps!
Answer:
π
Step-by-step explanation:
The standard form of the sine function is
y = a sin(bx + c)
where a is the amplitude, period = 
and
phase shift = - 
here b = 
, c = - 
phase shift = - 
= × 2 = π
