Answer:
c) 2 + 3 = 5 TRUE
d) 2 + (–3) = -1 True
Step-by-step explanation:
When adding integers (positive and negative whole numbers), there are three cases:
- Positive and positive increases and sum is positive. Ex. 4 + 6 = 10
- Positive and negative where you subtract and take the sign of the larger number. Ex. 3 + -8 = -5 or -3 + 8 = 5
- Negative and negative decrease and the sum if negative. Ex. -4 + -6 = -10.
Use these rules to simplify each expression.
a) 2 + (–3) = -1 not 1 FALSE
b) –3 + 2 = -1 not 5 FALSE
c) 2 + 3 = 5 TRUE
d) 2 + (–3) = -1 True
Well hmmm let's say you take the car and go in the city for 60 miles with it, well, the car can do 60 miles per gallon, since you just drove it for 60 miles, you only spent 1 gallon of gasoline then.
that only happens if you drive it for 60 miles, what if you drive it for more, let's do a quick table on that,

and so on, now let's check if you less than 60 miles,

so, if you divide the amount of miles driven, by 60, when you have driven it for 120 miles, 120/60 is just 2, and the cost is for 2 gallons, or 3.6 * 2, which is 7.2 bucks, for 180 miles is 180/60 or 3 gallons for 3.6 * 3 bucks, and so on.
now, what if you drive it instead for "m" miles?
For 64 it’s A. , C. , D. and for 3 it’s D. and F
Answer for 11-13: m<2: 150, m<6: 150, m<7: 150
Step-by-step explanation:
There is 180 degrees in a straight line. If one part of the line (angle) is 30 degrees, then the other part is 150. If you look at the image, you would see that m<2 is congruent to m<6 ,which means same, and m<7 is congruent to m<3.
Answer for 14-16: m<EBG: 150, m<AGH: 150, m<DHF: 30.
Step-by-step explanation:
4x = 150 2x + 50 = 150
x = 37.5 2x = 150 - 50
4(37.5) = 150 2x = 100
x = 50
2(50) + 50 =
100 + 50 = 150
