Answer:
c
Step-by-step explanation:
I’m not 100% sure but i think:
u can multiply 3 on both sides
3x+12=6
subtract 12 from both sides
3x=-6
therefore
x=-2
hope that helps
First we will find the average production for each machine:
For old machine:
(10) / (2) = 5 widgets / hour
For new machine:
(30) / (3) = 10 widgets / hour
We define t:
t = Amount of time in hours:
The equation sought is:
5 + 10 = 75 / t
Clearing we have:
t = (75 / (5 + 10))
t = 5 hours
Answer:
Working together, it will take the two machines to produce 75 widgets about:
t = 5 hours
Solution:
Given: 35.052
The standard form is: 35.052
3 is in the tens place. 3 = 3 × 1
5 is in the tens place. 5 = 5 × 1
0 is in the tenths place. 0.0 = 0 × 1/10
5 is in the tenths place. 0.05 = 5 × 1/100
2 is in the tenths place. 0.002 = 2 × 1/1000
