For this case we have the following solution.
 First, let's give the variable a name:
 Let
 x = gallons of water to be added
 For the 10% solution we have:
 0.1 * 8 = 0.8
 Then, for 5% we have:
 (0.8 / x + 8) = 0.05
 Rewriting:
 (0.8 / x + 8) = (5/100)
 Answer:
 An equation can be used to find x, the humber of gallons of water he should add is:
 (0.8 / x + 8) = (5/100) (option 2).

Debora [2.8K]

Answer:

1 m/s2

Step-by-step explanation:

Olive Oyl's weight = 10 × 9.81 = 98.1 N

This weight is a force acting downward because it is due to gravity.

Popeye pulls Olive Oyl up with a force of 108.1 N. Both forces act vertically but in opposite directions. Hence their resultant, R, is their difference and is in the direction of the larger force.

R = 108.1 N - 98.1 N = 10 N

This force causes an acceleration, a, on the mass, m, of Popeye.

R = ma

a = R/m = 10 N/10 kg = 1 m/s2

Is (0,5) a solution to the equation y=2x?​
klio [65]

Answer:

No.

Step-by-step explanation:

If (0,5) is a solution to y=2x, then 5=2(0) has to be true.

It is not because 5=2(0) is not true.

2(0)=0 and 0 is definitely not 5.

An example of a point on y=2x is (5,10) since 10=2(5) is true.
