Answer:
Step-by-step explanation:
So basically what you want to do is start with the distributive property.
-0.5(x+0.3) = 1.6x+0.9(x+4.8) would then equal -0.5x-0.15 = 1.6x+0.9x+4.32.
Then, add the matching terms on the right side (the x values) 1.6x+0.9x =2.5x
Your equation should the look like -0.5x-0.15 = 2.5x+4.32.
Next, add -0.5x to 2.5x giving you 3x
The equation will look like -0.15 = 3x+4.32
After that subtract 4.32 from -0.15 leaving you with -4.47=3x
Divide 3x from both sides
Your answer should be x= -1.49.
I hope this was helpful and not super confusing! Also if anything is incorrect let me know! :)
X(x+2)=224x2+2x-224=0(x+16)(x-14) =0x= 16 or 14
the answer is 16 and 14
Answer:
y=-x-3
Step-by-step explanation:
Slope intercept form is y=, and so we had to get the x to the other side. To do that you would subtract x from each side and then you get your answer.

Answer:
5 ham sandwiches
Step-by-step explanation:
To find the number of ham sandwiches sold, we should find the pair of numbers that have a difference of 6 and add to 16.
- 1 ham sandwich, 7 turkey sandwiches = 8 sandwiches
- 2 ham sandwiches, 8 turkey sandwiches = 10 sandwiches
- 3 ham sandwiches, 9 turkey sandwiches = 12 sandwiches
- 4 ham sandwiches, 10 turkey sandwiches = 14 sandwiches
- 5 ham sandwiches, 11 turkey sandwiches = 16 sandwiches
While this method isn't always very efficient, it worked pretty well for this case!
Therefore, the answer is 5 ham sandwiches.
