Answer:
One hundred and fifty 40 pounds boxes and twenty 75 pounds boxes
Step-by-step explaination:
The maximum amount he can haul in one load is 7500 pounds
150 × 40 pounds boxes = 6000 pounds
20 × 75 pounds boxes = 1500 pounds
6000 pounds + 1500 pounds = 7500 pounds
Let length of the hypotenuse = 3x and length of given leg be x feet.
then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81
so x = 9 and 3x = 27
Hypotenuse is 27 feet and the leg equals 9 feet.
Answer:
A. 9x^4 and 3x^5y
Step-by-step explanation:
there are two ways to solve this:
first way:
You can solve this my substituting numbers for x and y in this case i used 2 for x and 3 for y and see which one is equal to the original equations
the second way is the regular way
when you add or subtract numbers with variables and exponents you want to add the constants and add the exponents in this case
is the same as
=
and you can do the same process for subtraction
= 
Answer:
Missing length = 20
Step-by-step explanation:
Ratio is 16/20=4/5
25×4/5=20
You would need to do 10,125/45 = n, and in which case we just solve.
10,215/45=227, so there are 227 napkins in each box.
Hope this helps and have a nice day:)
