Which number line represents the solution set for the inequality -4(x + 3) 3-2-2x? -7 -6 -5 -4 -3 -2 -1 0 1 G 4 4 4 6 OT 7 -7 -6
Ksenya-84 [330]

Answer:

Option (1)

Step-by-step explanation:

Given inequality is,

-4(x + 3) ≤ -2 - 2x

Further solve this inequality,

-4x - 12 ≤ -2 - 2x

-4x + 2x - 12 ≤ -2 - 2x + 2x

-2x - 12 ≤ -2

-2x - 12 + 12 ≤ -2 + 12

-2x ≤ 10

-x ≤ 5

x ≥ -5

Therefore, on a number line draw an arrow starting with a solid circle (because of equal to sign) and moving towards the numbers greater than -5.

Option (1) is the answer.

(11x - 1)<br> (20x – 3)<br> 151°
IgorC [24]

Answer:

x= 1.6 degrees

Step-by-step explanation:

to find the missing angle 180 degrees - 151 degrees

29° is the missing angle at the bottom ryt of the triangle.

all angles in triangle add upto 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x= 1.6°

What is the quotient of 42/3 divided by 4 1/5
Nutka1998 [239]

Answer:

\large\boxed{4\dfrac{2}{3}\div4\dfrac{1}{5}=1\dfrac{1}{9}}

Step-by-step explanation:

First step:

Convert the mixed numbers to the improper fractions:

4\dfrac{2}{3}=\dfrac{4\cdot3+2}{3}=\dfrac{14}{3}\\\\4\dfrac{1}{5}=\dfrac{4\cdot5+1}{5}=\dfrac{21}{5}

Divide by a fraction is the same as multiply by the reciprocal of this fraction.

Therefore:

4\dfrac{2}{3}\div4\dfrac{1}{5}=\dfrac{14}{3}\div\dfrac{21}{5}=\dfrac{14\!\!\!\!\!\diagup^2}{3}\cdot\dfrac{5}{21\!\!\!\!\!\diagup_3}=\dfrac{2\cdot5}{3\cdot3}=\dfrac{10}{9}=1\dfrac{1}{9}
