3000/30=100every day
100/25=4
So she buys 4 L of milk every day.
So t=4.
Answer:
Step-by-step explanation:
Given that there are three variables satisfying the equation
Here each x is given to be a positive integer
i.e. solution set for each of the variable can be any integer from 1 to 20 at most.(because if two other integers are 1 each third has to be 20)
Hence solution set can be of the form
If x1 =1, there are 20 solution sets
If x1 =2,there are 19
...
If x1 =20 there is 1 set
Hence total solutions can be
Answer:
The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
Step-by-step explanation:
Answer: 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9+3.5g=11−0.5g
9+3.5g=11+−0.5g
3.5g+9=−0.5g+11
Step 2: Add 0.5g to both sides.
3.5g+9+0.5g=−0.5g+11+0.5g
4g+9=11
Step 3: Subtract 9 from both sides.
4g+9−9=11−9
4g=2
Step 4: Divide both sides by 4.
4g/4=2/4
g=1/2
Since line l and line m are cut by the transversal and angle 3 and 5 are supplementary, that means they are consecutive interior angles which proves that the two lines are parallel.
