Answer: x ≥ [tex]\frac{-2}{5}[/tex]

Step-by-step explanation:

I cannot see what the student did wrong in your question, so I solved for x in the equation...

[tex]5x + 2[/tex] ≥ [tex]x + \frac{2}{5}[/tex]

1. subtract x from both sides

4x + 2 ≥ [tex]\frac{2}{5}[/tex]

2. subtract 2 from both sides to isolate 4x

4x ≥ [tex]\frac{-8}{5}[/tex]

3. divide both sides by 4

x ≥ [tex]\frac{-2}{5}[/tex]

First plot the points that you are given. If a point is below the x-axis, then it is considered negative.

I hope this helps. I’m not sure what points you are given.

Answer:

87 days

Step-by-step explanation:

First if she already made 304 cranes and she makes 8 a day. Simply divide 304 by 8. You would then get 38. Next divide 1,000 by 8. You would get 125. You would subtract the total from how many days you need; 125, to how many days you already spent; 38. 125 - 38 = 87. 87 days are needed to make paper cranes.

Answer:

Equation: 7x + 8x = 180

x = 12

∠CBA = 84

∠CFH = 96

Step-by-step explanation:

We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.

We know that the sums of two angles on a straight line are going to be equal to 180.

∠CBA = 7x

∠CFH = 8x

To find the value of x, we must do the following:

7x + 8x = 180

15x = 180

15x/15 = 180/15

x = 12

Now we just substitute to find the angle measures:

∠CBA = 7 · 12 = 84

∠ CFH = 8 · 12 = 96

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

8x + 4 = 28

subtract 4 from both sides

8x + 4 - 4 = 28 - 4

8x = 24

divided both sides by 8

8x / 8 = 24 / 8

x = 3

Step-by-step explanation:

to find the mean you add up all  of the numbers and then divide by the numbr of numbers there are. So to add them all up that will be 3+5+0+4+7+5+5+3=32

so then you divide 32 by 8 which equals 4.

Answer:

1.50x>2.25x+9.00

Step-by-step explanation:

Because the 1.50 has to go their because 2.25 is greater than 1.50, the 9.00 is at the end because their is not a variable. How to know were theh variables go is the each.

She purchased a new lemon squeezer for $9.00.

The cost of the ingredients for each serving of lemonade is $1.50.

She will be selling each serving of lemonade for $2.25.

The inequality that represents the minimum number of servings of lemonade is 1.50x>2.25x+9.00.

We have given that,

Malika is making lemonade to sell at a school fundraiser.

The total cost is the addition of all the costs.

Malika must sell for the money from her sales to exceed the total cost of making the lemonade.

Because the 1.50 has to go there because 2.25 is greater than 1.50, the 9.00 is at the end because there is not a variable.

How to know where variables go is the each.

She purchased a new lemon squeezer for $9.00.

The cost of the ingredients for each serving of lemonade is $1.50.

She will be selling each serving of lemonade for $2.25.

Therefore we get the inequality that represents the minimum number of servings of lemonade is 1.50x>2.25x+9.00.

Divide 2 on both sides

⇒ Option A

The two possible answers for the third side of the right triangle are 6 and 24.

The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

So, a difference of two sides <x< sum of two sides, will give you the possible length of a triangle.

Sarah said, "There is only one possible third side for a right triangle with two sides measuring 9 units and 15 units.'

The two possible answers for the third side of the right triangle are;

[tex]\rm 15-9 < x < 15+9\\\\6 < x < 24[/tex]

The possible length of the third side of a triangle.

For checking the possible length:

15 + 9 > 7 (a+b>c)

9 + 7 > 15 (b+c>a)

7+ 15 >9(a+c>b)

Which satisfy the triangle inequality theorem.

Hence, the two possible answers for the third side of the right triangle are 6 and 24.
