3 + 10 = 13
2x + 5x = 7x
14 ÷ 2 = 7
3x = 12

Answers

I think the last one because a open statement contains at least one blank that becomes true or false when it’s filled in if you fill x with 4 you will get 3(4) 3*4=13 so if that blank was filled in with 4 it would be true

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

Answers

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:

{2.5, 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}

A baseball coach order hats for his team. Each hat cost $10. The shipping charger is $6. The total cost of the order must be less than $125. Which inequality can be used to solve?

Answers

The answer should be:

10h + 6 < 125

Answer:

10x + 6 < 125

Step-by-step explanation:

Hi,

10x is the cost per hat. 6 is the charging fee. 125 is the total cost of the order. We put x because we don't know how many hats they're going to buy. 6 is the amount they pay no matter what. And < is used because the total cost has to be less than 125, not less than or equal to, but LESS than.
