30-f+8f=30
30+7f=30
Move +30 to the right side. Sign changes from +30 to -30.
30-30+7f=30-30
7f=0
Divde by 7
7f/7=0/7
Cross out 7 and 7, divide by 7. Becomes 1*1*f=f
f=0
Answer: f=0
Answer:
Rate of change in elevation = 0.6 in/year
Step-by-step explanation:
Note:
Current elevation (Missing) = 7,602 feet
Given:
Old elevation = 7,602 feet
Number of year = 7,600
Find:
Rate of change in elevation
Computation:
Change in elevation = 7,602 - 7,600
Change in elevation = 2 ft
Change in elevation = 2 x 12 = 24 inches
Rate of change in elevation = 24 / 40
Rate of change in elevation = 0.6 in/year
We can write the equation 9x=4500
Now we just solve for x by dividing both sides by 9 to get:
x=500
Hope this helps!
In 1 minute the copy machine copies = 24
That means
In 60 seconds the copy machine copies = 24
First we need to convert 5 minutes and 30 seconds to seconds
Then
5 minutes and 30 seconds = (5 * 60) + 30
= 300 + 30
= 330 seconds
So
In 330 seconds the copy machine will copy = (24/60) * 330
= 4 * 33
= 132
So in 5 minutes and 30 seconds the copy machine will copy 132 copies.
Answer:
x= -2 is correct answer
Step-by-step explanation:
3(-2×-2)+13(-2)+14=0
3(4)+13(-2)+14=0
12+(-26)+14=0
12-26+14=0
12+14-26=0
26-26=0
0=0
