Answer:
Question 1: A
Question 2: C
Step-by-step explanation:
The answer to question 1 is A. I know this is correct because Max needs to earn 108 dollars for the headphones he wants so the amount of money he earns per hour which is 15, times the amount of hours he needs to work which is x has to be greater than 108. So, the inequality equation has to be 15x > 108 which is answer A.
The answer to question 2 is C. I know this is correct because Felicia has 2 sisters which make 3 sisters in total to pay for the gift. They all pay evenly, so the first part of the equation would be 3x. The cost for the gift is less than 80 dollars, so we write the inequality equation like 3x < 80 which is answer C.
It will be 69 because 68 is wrong and 69 is right
Answer:
0.90
Step-by-step explanation:
I entered it onto my calculator, but if you'd like an explanation as to how just ask.
Subtract 5a from both sides
-3=3a+6
Subtract 6 from both sides
-9=3a
Divide by three
a= -9/3 (which is -3)
Remember what you do to one side you must do to the other
Answer:
168 cm³
Step-by-step explanation:
The base of the prism is a right triangle whose hypotenuse is 10 cm and one other side is 6 cm.
So, the third side of the triangle = 
cm.
{Since we have applied the Pythagoras theorem.}
Hence, the area of the base triangle is 
cm².
Therefore, the volume of the prism is = 
cm³ {Since volume of a prism is given by ( Area of the base triangle ) × ( Height of the prism )}
