Answer:
9.936
Step-by-step explanation:
In(x+5)*x=5
ln(x^2+5x)=5
e^5=x^2+5x
148.4131=x^2+5x
x^2+5x-148.4131=0
x is 9.936 because logs can't be negative
Answer: The required length of steel is 270 cm.
Step-by-step explanation:
Since we have given that
Number of stems = 6
Length of each stem = 45 cm
So, we need to find the length of steel used in the frame.
So, Length of steel = Number of stems × Length of each stem
So, the length of steel becomes
Hence, the required length of steel is 270 cm.

You just have to multiply straight across. Multiply the numerators for the new numerator, and the denominators for the new denominator.
5*3=15
4*8=32
15/32 is the answer (b).
Answer:
30 pounds of raspberries and 50 pounds of blueberries
Step-by-step explanation:
Let's use b to represent blueberries and r for raspberries. Each pound of raspberries costs $1, so to find the total cost of raspberries we use 1r, which is just r. For blueberries, we do 3.25b.
r+3.25b=192.5
We also know that we can combine the numbers for 80 total pounds.
r+b=80
We can subtract the two equations we have made to eliminate the r and solve for b.
2.25b=112.5
We divide both sides by 2.25.
b=50
We know that r+b=80, so if b is 50 then r must be 30.
Have a wonderful day! :D
