Okay so this is going to be confusing but work from right to left. since you can’t do 0-5, borrow from the one next to the zero on the top, cross out the one and put zero and add a one on top of the zero which makes it 10. now you can do 10-5 to get 5. put the five down below the line. next solve the second column of numbers ( second to the right). since you cannot do 0- 3, like the last one, you have to borrow from the 7 over to the left. take one from there and cross the seven out and put a six. now you have 10-3 which is 7. put the 7 down. now do move to the next column and do 6-2 to get 4. put the four down below the line. move to the next column and do 2-2 to get 0. put the zero down below the line. lastly, we know the answer has to be negative so we are going to do 2-7 to get -5. put -5 down below the line and together to get the answer -502,275. i know that was very confusing but i hope it helped a little bit. i added a picture to clarify a little

Answer:
D.120
Step-by-step explanation:
The sides AB and AC are equal and thus the angles they form with BC should be equal . Since now angle ABC is 30 then application of sum of angles in a triangle as a constant(180 degrees) we can subtract 60 degrees from it which gives 120
Answer:
7
Step-by-step explanation:
35 / 7 = 5
49 /7 = 7
Answer:
Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
Step-by-step explanation:
Since either job takes 2 hours to complete, the total number of jobs that Kevin can complete working 54 hours a week is:
Since replacing shocks gives him a greater income, he should aim to do as little break replacements as possible and as many shock replacements as possible in order to maximize income.
If he has to complete at least 6 break replacements out of the 27 jobs possible, the number of shock replacements he should do is:
Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
