Answer:
-23a + 64
Step-by-step explanation:
-8(-2a + 4a - 8) - 7a
First combine like terms
-8(2a - 8) - 7a
Then distribute
-16a + 64 -7a
Combine like terms
-23a + 64
I have a simple easy way of doing this. First you find the weight of the item, and then you would divide the cost by the weight. that's it
First, you'll use the "Log power rule," which says that
. In this case, you're going from the form on the right (with p in front of the log) to the form on the left (with p in the exponent position). So, the expression becomes:
Then, you'll use the "Log product rule," which says that
. Again, you're going from the form on the right to the form on the left (basically, from the sum of the logs, to a log of the products). So you get:
There's your expression simplified into a simple logarithm.
So the formula for that is:
(total - difference) ÷ 2 = smaller number
(total + difference) ÷ 2= larger number
In this case, Judy is more so we do second fomula:
(12 + 6) ÷ 2 = 9 hits homerun
and Marnie will hit 12 - 9 = 3 hits
step 1
convert pounds to ton
1 ton------> 2204.62 lb
<span>each crate weighs 80 pounds
so
by proportion
1/2204.62=x/80
x=80/2204.62-----> x=0.036 ton
each crate weighs 0.036 ton
step 2
divide 2 ton by 0.036
2/0.036=55.11 crate----------> 55 crate
the answer is
</span>the greatest number of crates that can be loaded onto the elevator is <span>55
alalternative method
</span>step 1
convert ton to pounds
1 ton------> 2204.62 lb
a freight elevator has a weight limit of 2 ton
2 *2204.62 -----> 4409.24 lb
step 2
each crate weighs 80 pounds
divide 4409.24 by 80
4409.24/80=55.11 crate----------> 55 crate
