<h3>
2 Answers: B and D</h3>
===================================================
Explanation:
Choice B is one answer because -2 and 2 are additive inverses that add to -2+2 = 0
Choice D is a similar story. We have -5+5 = 0
In general, if x is some number then -x is its additive inverse. So we can say x+(-x) = 0 or -x+x = 0. In short, additive inverses add to 0.
Use division or long division (ignore the decimal point)
Then put the decimal in the same spot as the dividend (the number being divided)
1 person make 3 cakes.
40 people make 40 x 3 = 120 cakes.
15% were chocolate = 15% x 120 = 0.15 x 120 = 18
Answer: There were 18 chocolate cakes made for bake sale.
Answer:
105
Step-by-step explanation:
55+50+x=180
x=75 this is the other inside angle. to find b, you need to take 75 and subtract it from 180. this is because a straight line is equal to 180 degrees
Perimeter= 2l+2w
126= 2l+2w
l=2w
Substitute the value for l
126= 2(2w)+2w
126= 4w+2w
126=6w
21=w
Plug the value for w in to find l
l=2(21)
l=42
Final answer: Length-42 ft, Width-21 ft
