Answer:
x < -6
Step-by-step explanation:
-2x -4 > 8
-2x +4 >+4
-2x >12
/-2 > /-2
x < -6
remember to flip the inequality sign whenever you divide by a negative number :)
The system of equations are:
2x − 4y = 6
−3x + 3y = 9
To eliminate x, you should:
1. multiply first equation with 3
2. multiply second equation with 2
3. add the new equations you got
So your answer is A.
The gas cost 35 dollars and the water cost 15 dollars
Answer:
Excess time = 1.2 hour
Step-by-step explanation:
Given:
Total time = 24 hours
Talking on phone = 17 %
Sleeping = 33%
Going to school = 25%
Studying = 4%
Eating = 8%
Computation:
Watching TV percent = 100% - Talking on phone - Sleeping - Going to school - Studying - Studying - Eating
Watching TV percent = 100% - 17% - 33% - 25% - 4% - 8%
Watching TV percent = 13%
Time taken by school = 24 x 25%
Time taken by school = 6 hour
Time taken by watching T.V. and Talking on the Phone = 24 x (13% + 17%)
Time taken by watching T.V. and Talking on the Phone = 7.2 hour
Excess time = 7.2 - 6
Excess time = 1.2 hour
Answer:
Step-by-step explanation:
A =1/2 *h (x+y)
A =hx+hy/2
A*2 =hx+hy
2A =hx+hy
2A - hy = hx
(2A -hy)/h = x
