What value of x is in the solution set of 9(2x + 1) < 9x – 18?

1 answer:

7 0

To solve these kinds of problems, it is necessary to isolate x:

9(2x + 1) < 9x - 18

Distribute 9:
18x + 9 < 9x - 18

Subtracting 9 from both sides of the equation:
18x + 9 - 9 < 9x - 18 - 9
18x < 9x - 27

Subtracting 9x from both sides of the equation:
18x - 9x < 9x - 27 - 9x
9x < -27

x < -3

Therefore, values of x < -3 will satisfy the given equation.

A triangle has a perimeter of 33cm. If the three sides of the triangle are n, 3n−4, and 3n−5, what is the length of each side?

lara [203]

Just did this one.

The perimeter is the sum of the sides.

n + (3n - 4) + (3n - 5) = 33

7n - 9 = 33

7n = 42

n = 6

3n-4=18-4=14

3n-5=13

Check: 6+14+13=33, good

Answer: 6 cm, 14 cm, 13 cm

122 1/4

Step-by-step explanation:

Hope this helps! :)

(12x12) 12x $\frac{2}{3\\}$ x12) / (3/2 x3/2)

PEMDAS = parathesis exponents multiplictation division add subtract.

12x12=24

3/2x3/2=9/4

12x2/3=8x12=96

so 24+96=120

9/4 can be like 4x2=8 so i remaing

120+2=122 1/4?
