Answers

Answer 1

Answer:

Answer:

Option B is the correct answer.

Step-by-step explanation:

A. Jane collects 12 seashells and then loses 12. This combines to become 0. as first Jane gets 12 shells and then loses same 12 totaling to 0.

B. Sharon lost 8 pounds and then gained 10 pounds. This does not combine to become 0. As Sharon lost 8 pounds then gained 10 making it a total of $10-8=2$ pounds.

C. A business's profit if its income is equal to its expenses. When the income and expense are equal, the profit is 0. Like you earned $100 and you spent $100, so you have basically 0.

D. Frank wins five dollars and pays back a $5 debt to a friend. This also combines to get 0. Frank gets $5 and then loses it by paying debt, so he is left with 0.

Therefore, option B is the only correct answer.

Okay. You have seven of her hands, and they are all 5/12 of a foot long.
There are two ways to do this: multiply or add, which ever you have been doing in class.
Adding way: 5/12 + 5/12 +5/12 + 5/12 + 5/12 + 5/12 + 5/12 = 35/12 You would need to turn it into a mixed number, which would be 2 11/12
Multiplication way: 7/1 x 5/12 = 35/12, same as 2 11/12.

Hi!

$(2)/(3)=(x)/(12)$

$(x)/(12)=(2)/(3)$

$(12x)/(12)=(2*12)/(3)$

$(12x)/(12)=x$

$(2*12)/(3)=8$

$Answer---->x=8$

Explanation: First you had to switch sides to the problem. Then multiply by 12 from both sides. And simplify by 12x/12=8 or 2*12/3=8. And the answer should be x=8 is the right answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie

Answer:

$(a)/(c)=(b)/(d)\ \Leftrightarrow\ (a)/(b)=(c)/(d)$

Step-by-step explanation:

The cross products related to the proportions shown here are ...

$(a)/(d)=(c)/(b)\ \Rightarrow\ ab=cd\n\n(a)/(c)=(b)/(d)\ \Rightarrow\ ad=bc\qquad\text{same as the fourth one}\n\n(d)/(a)=(c)/(b)\ \Rightarrow\ bd=ac\n\n(a)/(b)=(c)/(d)\ \Rightarrow\ ad=bc\qquad\text{same as the second one}$

If 3b+2-6b=32+5b-2b, find b

Answers

I believe the answer is b= -5

Answer:

b=-5

Step-by-step explanation:

3b+2-6b=32+5b-2b(first you should collect like terms on each side.) so

3b-6b+2=32+5b-2b (lessen thing by both sides.)

-3b+2=32+3b (then you collect terms to one side)

-3b-3b=32-2

-6b=30 (you divide both sides by 6)

-b=5 (since b cannot be a negative u divide both sides by -1)

so..b=-5
