2(4 + 2x) ≥ 5x + 5

First, we will need to expand our problem. Expanding is basically removing the parentheses. To do this, we will look at the first part of the problem to begin with. 2(4 + 2x). Since parentheses usually mean multiplication, we can start with 2(4). So, 2 × 4 = 8. We'll do the same thing with 2(2), 2 × 2 = 4. 
8 + 4x \ge 5x + 5

Second, our next step is to subtract 4 from each side. We are trying to get the variable (x) on one side of the problem by itself. 
8 \ge 5x + 5 - 4

Third, we can now simplify (5x) + 5 - (4). I put parentheses around what we are going to focus on. Subtract 5x - 4 to get 1, which can be put as the variable (x). Now we have, x + 5.
8 \ge x + 5

Fourth, let's subtract 5 from each side now. This will set up 8 - 5 which equals 3. 
3 \ge x

Fifth, we can switch sides now to get the result of this problem.
x \le 3

Answer: x \le 3

Equation: -5 3/4- 3 1/2 Please help meh. ​
vampirchik [111]

Answer:

-9\frac{1}{4}

Step-by-step explanation:

-5\frac{3}{4}-3\frac{1}{2}

Step 1: Factor out the common term -1

=-\left(5\frac{3}{4}+3\frac{1}{2}\right)

Step 2: Add the whole numbers

5 + 3 = 8

Step 3: Combine the fractions:

\frac{3}{4}+\frac{1}{2} = \frac{5}{4}\\\\=-\left(8+\frac{5}{4}\right)

Step 4: Convert the improper fractions to mixed numbers

\frac{5}{4} = 1\frac{1}{4}\\\\=-\left(8+1\frac{1}{4}\right)

Step 5: Add the numbers

8 + 1 =9 \\\\=-9\frac{1}{4}

Therefore, the answer to the equation is -9\frac{1}{4} in fraction, and decimal; 9.25

Help? what should i choose
igomit [66]

Answer:

Step-by-step explanation:

Angles on a straight line add up to 180 so:

180-110 = 70

As this is an isosceles triangle,

y must be 70.

We know y is 70 and there are 2y and one x. A triangle also adds up to 180.

This means:

2y+x = 180

2(70)+x = 180

140+x = 180

x = 40

x = 40  y = 70

(2 x 106) x (0.00009) = ?
RSB [31]

I think you meant to write

(2 × 10⁶) × 0.00009

First, convert 0.00009 to scientific notation:

0.00009 = 9 × 10 ⁻⁵

Then

(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)

… = (2 × 9) × (10⁶ × 10 ⁻⁵)

… = 18 × 10¹

… = 1.8 × 10²
