Which number is missing from the final triangle?

Answer is 48.
The way to solve this is on the left hand side of the triangle you would add the top and the very left number. In this case 6+2=8. Next you will multiply the number you just found from the two left numbers to the very right number. So now you have 8x6=48.
Just use your problem solving skills with guessing and checking. For example in the first one you will know that 8x4 is already too big of a number so you need to make a smaller number. Then try adding and subtracting.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
