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:
6 times
Step-by-step explanation:
We will have to divide in order to solve this problem.
÷
We will have to find the reciprocal of 1/8, which is basically flipping it, so it is 8.
After, we will have to multiply 3/4x8. The product would come out as 24/4, and if you simplify it, the answer will be 6 times.
15+16+10 =41
BH= 41
Bd=15
Df=16
Fh=10
