Given b equals -3, determine if it is a solution to 4b - 6 = - 18.
So, we have our given which is b = -3, and we are asked to determine if it a solution to the above equation.
To do this, we can plug -3 in for b and see if it works out.
Work:
Plug in -3 for b.
4(-3) - 6 = - 18
-12 - 6 = -18
-12 - 6 = - 18
Thus, b = -3 is a viable solution for the equation of 4b - 6 = -18.
Answer:
Tacos for adults: 13*3
Tacos for children: 17*1
Total: 39+17
=56
And in each package there will be 8 tacos
So, 56/8 = 7 = No. of tacos needed.
So the corrrect answer is<u> A 7, because (13 x 3 + 17) + 8 = 7</u>
The sum of the two smallest numbers has to equal a number greater that the largest one. Or, how some people prefer it, the sum of any two numbers of the set has to be a greater number than the third one.
So, the set of sides 7,9,17 does not form a triangle.
because 7+9= 16, which is less than the greatest number, 17.
