Answer:
b=4
Step-by-step explanation:
4b+5=1+5b (subtract 4b on both sides to get the b's together)
-4b -4b
5=1+5b-4b (subtract 1 from both sides)
-1 -1
4=1b (divide by 1)
b=4

Answer:
perimeters of the rectangle=p=46.014 metres
Step-by-step explanation:
Given that:
Length (l) = 21 m
Area of rectangle(A) = 42.15 meter-square
Width (w)=?
Required data:
Perimater of Rectangle=p=?
Calculation:
As we know that Area of rectangle=A=l*w
Putting the value we get
42.15 m(square)=(21 m)*w
or w=42.15/21
or w=2.007 m
Now to find perimters of rectangle we know that
p=2(l + w) metres
putting the values
p=2(21+2.007) metres
p=2(23.007) metres
p=46.014 metres
Answer:
The interest rate = 6 %
Explanation:
We have I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.
Here principal, p = 200 $
Number of years , t = 3
Interest received, I = 36$
We need to find rate of interest.
Substituting
36 = 200 x r x 3
r =
= 0.06 = 6%
The interest rate = 6 %
Answer:
44
Step-by-step explanation:
first we take the number he gave to his mom and put it to the side for later then we see that 8 bags had 4 candy bars each so 8*4 is 32 then we bring the 12 bars that he gave to his mom and add that to 32 so 32+12 and the answer would be 44
