Answer:
Tanaysha replace 8 by ( 10 -2) to solve the given expression.
Step-by-step explanation:
Here, the given expression to be solved is:
72 - 8 .......... (1)
Now, as we know: 8 = 10 - 2
Replacing the value of 8 with ( 10 - 2), we get:
72 - 8
= 72 - (10 - 2)
= 72 - 10 + 2
= (72 + 2 ) - 10
Now, adding ( 72 ) and ( 2) , we get:
= 74 - 10
Subtracting 10 from 74, we get:
= 64
So, Tanaysha replace 8 by ( 10 -2) to solve the given expression.
Answer:
The value of x = 100 ft^3/ day
Step-by-step explanation:
We need to look at what amount of water comes in and what amount of water leaves
What comes in: x ft^3/ day
What leaves : 500x ft^3/ day
We start with 146 000 ft^3
Water in tank = what we start with + what comes in - what leaves
water in tank = 146000 + x*d - 500*d where d is the number of days
After 365 days , the tank has 0 ft^3 of water
0 = 146000 + x*365 - 500*365
Multiply
0 = 146000 + 365x - 182500
Combine like terms
0 = -36500+365x
Add 36500 to each side
36500 = 36500-36500+365x
36500 = 365x
Divide by 365
36500/365 = 365x/365
100=x
The value of x = 100
Answer:
$504
Step-by-step explanation:
Step one:
given data
A shirt that cost $420
we are told that the shirt was on a discount sale of 20%, so when the discount is over the price will return to $420, we are then told that the shirt was marked up 20%.
Step two:
Hence the new cost is
=20/100*420+ 420
=0.2*420+420
=84+420
=$504
2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
y=-7x-6
-3 i tired to make it a fraction
Step-by-step explanation:
just solve for the formula y= mx +or- b
