Answer:

(x + 4)/(2x - 1) < 0 => x + 4 < 0 => x > -4

2x - 1 ≠ 0 => x ≠ 1/2

(-4 , 1/2) U (1/2 , ∞)

Answer:

x < 5

Step-by-step explanation:

Given that:

(x+4 over 2x-1)<0

It can be written as:

x + 4/2x-1 <0

Multiplying both sides by 2x -1

x+ 4 < 2x -1

By simplifying:

Take terms with x on left side and constants on right side:

x - 2x < -1 - 4

- x < -5

"-" sign will be cancelled from both sides

x < 5

i hope it will help You!

The football team ordered 2 pizzas, they didn't eat 1/12 of one pizza and 2/4 of the other. How much pizza was left?
kodGreya [7K]
To equally divide the pizzas, let's use a similar point to base on the remaining pizzas. On the first pizza 1/12 was not eaten an the other was 2/4. Use 12 as the base parts. 1/12 +2/4. 2/4 is equal to 1/2, so let's used 6/12 (also 1/2) to replace 2/4 to add both fractions. 1/12+6/12=7/12.

The sum of two numbers is 30 and their difference is 6
Studentka2010 [4]

I'm going to assume that you are trying to find the two numbers. Based on the information in the problem, we can create the following equations (where a and b are the two numbers):

a + b = 30

a - b = 6


We have a systems of equations. In this case, it would be easier to use elimination by adding vertically. This produces the result:

2a = 36

a = 18


To find b, substitute the value for a into one of the earlier equations:

18 + b = 30

b = 12


The two numbers are 12 and 18.

Answer:

75 cheeseburgers and 86 french fries

Step-by-step explanation:

This is a guessing math problem so do a random amount and change amount of items to get closer to the answer

81 x 3 = $243

80 x 1.50 = $120

243 + 120 = 363 -354 = 9 dollars

we need nine less dollars so 9/1.5 = 6 so six more fries

86 x 1.5 = 129

75 x 3 = 225

129 + 225 = $354

Solve the following system of linear equations. 3x + 2y = 10 2x + 3y = 15/2 No solution y = (-3/2)x + 5 x = 3, y = -1/2 x = 3, y
frutty [35]
3x + 2y = 10 .....multiply by -2
2x + 3y = 15/2...multiply by 3
------------------
-6x - 4y = -20 (result of multiplying by -2)
6x + 9y = 22.5 (result of multiplying by 3)
-----------------add
5y = 2.5
y = 2.5/5
y = 1/2

3x + 2y = 10
3x + 2(1/2) = 10
3x + 1 = 10
3x = 10 - 1
3x = 9
x = 9/3
x = 3

solution is (3,-1/2)
