First start by multiplying:
-6/15 + 5/2 -3/30
then u can simplify the fractions, -6/15=-2/5 and -3/30=-1/10
-2/5 + 5/2 - 1/10, now find a common denominator in this case 10
-4/10 + 25/10 - 1/10
now add and subtract normally
answer:20/10 or 2
Answer:
30 parts
Step-by-step explanation:
We are given that machine produces 100 parts twice as fast as machine B does.
Machine produces 100 parts in 40 minutes.
We have to find number of parts produces by machine A in 6 minutes.
According to question
Machine A takes time to produce 100 parts =
Machine A and machine B produces parts at constant rate.
Machine A produces parts at the rate=
In one minute,Machine A produces =5 parts
In 6 minutes , machine B produces =
parts
Hence, machine A produce parts in 6 minutes=30
Answer:
w² - 2w + 4
Step-by-step explanation:
(w² - 4w + 14) - (2w + 10) = w² - 2w + 4

This means that the rocket was launched from a platform 112 feet above the ground.

What is an equation</h3>
An equation is an expression showing the relationship between two or more variables and number.
h is the altitude of the rocket x seconds after it was launched.
Given the function:
h(x) = -16x² + 96x + 112
The y intercept is at x = 0:
h(0) = -16(0)² + 96(0) + 112 = 112 feet
This means that the rocket was launched from a platform 112 feet above the ground.
The x intercept is at h(x) = 0:
0 = -16x² + 96x + 112
x = 7
The x intercept shows the time the rocket touches the ground was 7 seconds.
Maximum height is at h'(x) = 0
-32x + 96 = 0
x = 3
h(3) = -16(3)² + 96(3) + 112 = 256 feet
The maximum height is 256 feet.
