Answer:
Step-by-step explanation:Simplifying
3x + 8 = 2x + -21
Reorder the terms:
8 + 3x = 2x + -21
Reorder the terms:
8 + 3x = -21 + 2x
Solving
8 + 3x = -21 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
8 + 3x + -2x = -21 + 2x + -2x
Combine like terms: 3x + -2x = 1x
8 + 1x = -21 + 2x + -2x
Combine like terms: 2x + -2x = 0
8 + 1x = -21 + 0
8 + 1x = -21
Add '-8' to each side of the equation.
8 + -8 + 1x = -21 + -8
Combine like terms: 8 + -8 = 0
0 + 1x = -21 + -8
1x = -21 + -8
Combine like terms: -21 + -8 = -29
1x = -29
Divide each side by '1'.
x = -29
Simplifying
x = -29
Answer:
34 ounces
Step-by-step explanation:
20% = 6.8
1% = 6.8*20
100% = 6.8 * 20/100 = 34 ounces
2nd solve:
after pouring 20%, the remaining water was = 34 - 6.8 = 27.2
2nd time pour = 27.2 * 25 / 100 = 6.8 ounces
2/5=240
1/5=120
3/5=360
5/5=600
She spent $360 of the $600, so she spent $120 more then she saved
I believe the answer is b because
y is the total time to wait.
the more employees working would reduce the time by -70 with a base time of 300
Answer:
A(1,1)
Step-by-step explanation:
the system is :
2x-y=1
x+2y=3
so :
y = 2x-1 .....the line color : red
y= (-1/2)x+3/2......the line color : blue
the pair solution is the intersection point for this line : A(1 ; 1)
