Answer:
Step-by-step explanation:
It is given that, 
We need to find the value of 
As
Solving LHS
Now comparing the coefficients of 
In LHS the coefficient of is 25
In RHS the coefficient of is
It implies that,
So, the value of is 25.
Answer:
y = 46
Step-by-step explanation:
I'm assuming you wanted to solve for y.
x = 5
y = 8(5) + 6
y = 40 +6
y = 46
N/4.3 = 9.4
4.3 × n/4 = 9.4 × 4.3
n = 40.42
Answer: it will take them 48 minutes.
Step-by-step explanation:
John can mow a lawn in 80 minutes. This means that the rate at which he moans the lawn per minute is 1/80
Rocky can mow the same lawn in 120 minutes. This means that the rate at which Rocky can mow the same lawn per minute is 1/120
If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be
1/80 + 1/120 = 200/9600 = 1/48
Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,
1/48 = 1/t
t = 48 minutes
