So your equation would be 8a+10=11d-6
First: you would combine like terms so normally you would take away the smaller number. So to cancel out the negative 6 you added you add positive six to the negative 6 so you would get 0 and whatever you do to one side you have to do to the other so you would do 10 + 6. Your new equation would be 8a+16=11d. Now you do -16 to both sides. So your new equation would be 8a= 11d - 16. Now you divide by 8. So your final equation would be a=11d-2.
One JOB = 1 and 2 hours = 120 min
Tyler Rate per minute: 1/120 (in 1 minute he performes 1/120 of the job)
Dakota<span> Rate per minute: 1/90 (in 1 minute he performes 1/90 of the job)
Tyler's + Dakota's rate per 1 minute = 1/120 + 1/90 = 7/360 (Job/minutes)
7/360 of the job was performed in 1 minute
</span>a complete JOB =1 to be performed in x minutes (Rule of three)
x = 1x1/(7/360) that equals to 360/7 and x (time of both) = 51 min 42
Answer:
Just click an x on the graph for each number in the chart.
1/4 would have 4 x's
2/4 would have 2 x's
3/4 would have 1 x
1 would have 2 x's
Answer:
-24 + 16c
Step-by-step explanation:
There are a couple things we need to know here:
- We need to know how to distribute a negative
- We need to know that we cannot combine 24 and -16c, because we can only combine like terms (we can only combine terms that don't have a c with other terms that don't have a c).
To help distribute a negative, we can first write the problem like this:
-1 * (24 - 16c)
So all we're doing is multiplying -1 by 24 and by -16c, which will get us:
-24 + 16c, which is the answer.
