Answer:
20 percent
Step-by-step explanation:
20 percent
20% sorry if it's wrong
It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
Answer:
length = (x − 8) units and width = (x − 9) units
Step-by-step explanation:
We need to factor
x^2 - 17x + 72
We need two numbers whose product is 72 and whose sum is -17.
The numbers are -8 and -9.
x^2 - 17x + 72 = (x - 8)(x - 9)
Answer: length = (x − 8) units and width = (x − 9) units
Answer:
3 & 43/80
Step-by-step explanation:
take 17 and 11/16 and turn it into a mixed number
you will get 283/16
keep, flip, change
so you will keep 283/16, flip the sign so you are multiplying instead of dividing, and then change the 5/1 to a 1/5
then just multiply straight across
you get 283/80
then simplify and get 3 and 43/80
