Which of the following sets shows all the numbers from the set {0, 0.5, 1, 2.5, 3} that make the inequality 2a + 3 ≥ 8 true?

{2.5, 3}
{1, 2.5, 3}
{0, 0.5, 1}
{0.5, 1}

Answers

Answer 1

Answer:

A

Step-by-step explanation:

it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)

Answer 2

Answer:

{2.5, 3}

Step-by-step explanation:

2a + 3 ≥ 8

2a + 3 - 3 ≥ 8 - 3

2a ≥ 5

[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]

a ≥ 2.5

From the expression above, a is equal to 2.5 and any number above 2.5

∴The answer is {2.5, 3}

Answers

Answer: 23°

Step-by-step explanation:

First, we need to find the missing angle to the left of x

Let's take what we are given

which is 130°, As you notice the angle of 130° is on a straight line

A straight line is supposed to equal 180°

So we can take 180°-130° which will equal 50°

Now we know that the missing angle next to x is 50°

Now we need to take 107° and add it to 50

Which will equal 157°

Now to get x, we need to take 180°-157°

Which will equal 23°

x=23°
