The sum of 4 twelves and 7 sixteens
dolphi86 [110]

Answer: 160

Step-by-step explanation:

So here they are telling you that there are 4 twelves, a.k.a 4 groups of 12. Which means that you have to multiply 4 x 12 = 48

Then there are 7 sixteens, a.k.a 7 groups of 16.

Which also means that you have to multiply 7 x 16 = 112

Add both numbers and there you have your answer!

I hope you found my answer helpful! :)

Solve: -4x-8x+17=23<br> check solution
Sveta_85 [38]

Answer:

x = -1/2

Step-by-step explanation:

To solve the equation, we first need to combine like terms:

-12x+17=23

Simplify further:

-12x=6

Divide by -12 on both sides to get:

x = -\frac{1}{2}

To check  the solution, plug x back into the original equation and check if we get the correct answer:

-4(-\frac{1}{2})-8(-\frac{1}{2})+17=23

2+4+17= 23

23=23

Thus, it checks out and our answer is correct.
