The number line below models an integer problem. Which equation best represents the model?

A. -3+7=10

B. 7+(-3)=4

C. 7+(-10)=3

D. 10+(-3)=7

Note that the result is negative, and not positive. I'm assuming your teacher made a typo.

The negative 3 is because the upper arrow is in the negative region, to the left of the 0.

The lower arrow represents 7 since we start at 0 and move 7 units to the right.

The upper arrow represents -10 to indicate we move 10 units to the left.

We can think of 7+(-10) as 7-10 and that is the same as -10+7. To evaluate this without a number line, we can subtract 10-7 to get 3, but the result is negative because the 10 is larger and it is negative. It's like having 10 iou's and you pay off 7 dollars of debt. That means you're still 3 dollars in debt, which is represented by -3.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
