Food = 1/4
gasoline = 3/5
Total = 1/4 + 3/5 = 17/20
17/20 = 272
1/20 = 272 ÷ 17 = 16
20/20 = 16 x 20 = $320
Answer:
28'042.56
Step-by-step explanation:
2.6 x 107=278.2
6.3 x 16= 100.8
278.2x100.8=28'042.56
Last month, she had 100.....this month, 30 new members joined and 10 cancelled....thats basically the same as saying 20 new members joined...so there are now 120 members...at 10 per subscription = 120(10) = $ 1200 <=
Answer:
1. No solution
2. Infinite solutions
Step-by-step explanation:
1. To solve the system, set the equations equal to each other and solve for x.
2x - 5 = 2x + 7
-5 = 7
This is a false statement. This means there is no solution.
2. To solve the system, graph each equation.
y = -3/4 x - 5/2 has a y-intercept -5/2 and slope -3/4.
3x + 4y = -10 converts to y = -3/4x -5/2.
This graphs as the exact same line. This system has infinite solutions.
Answer:
x = 6, -8
Step-by-step explanation:
If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:
x - 6 = 0
and
x + 8 = 0
would yield the two solutions to the equation.
x - 6 = 0
Add 6 to both sides of the equation.
x = 6
So one of the solutions would be x = 6.
x + 8 = 0
Subtract 8 from both sides of the equation.
x = -8
So the other solution would be x = -8.
The two solutions are x = 6 and x = -8.
