Hey! For these questions I'd reccomend m4thm4y. Ps I replaced the a with 4.
Answer:
n=42
Step-by-step explanation:
The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:
3n-15-2n-16=11
Then we collect like terms together.
3n-2n-15-16=11
evaluating the above equation we get
n-31=11
n=11+31
=42
Answer:
310%
Step-by-step explanation:
Convert the fraction to a decimal, then multiply by 100.
Y=-1x+5
First find the slope with the points. (b2-b1)/(a2-a1) (-2-6)/(7-(-1)) which equals -8/8
Then find the solve for b
-2=-1(7)+b
-2=-7+b
5=b
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
