What addition statement does this show?
What addition statement does this show? A. 5 + 6 - 1

Answers

Answer 1
Answer:

Answer:

B) 5 + (-6) = -1

Step-by-step explanation:

First, take a look at the blue arrow on the bottom. It travels forwards 5 spaces, giving us +5. Because this arrow starts at 0, 5 will be the start of our equation. Next, take a look at the red arrow on the top. This arrow travels backwards 6 spaces, giving us -6. Here is what our equation should look like now:

5 + (-6) =

Now, solve for the answer. Follow the blue line forwards 5 spaces, then follow the red arrow backwards 6 spaces. The red arrow stops at -1, making our answer 5 + (-6) = -1.

A wrestler is trying to gain weight for an upcoming match. His current weight is 105. In the formula shown, W = weight, p = pounds and t = time(weeks). He has 6 weeks before his match and has a goal weight of 123 pounds. Determine the minimum number of pounds he must gain per week to meet his goal. A) 1 pound B) 2 pounds C) 3 pounds D) 4 pounds

Answers

Answer:

Option C) 3 pounds.

Step-by-step explanation:

A wrestler is trying to gain weight for an upcoming match.

He has a goal weight = 123 pounds

His current weight = 105 pounds.

How much weight he must gain for his goal = 123 - 105 = 18 pounds

He has only 6 weeks to achieve his goal, therefore we divide is goal (to gain 18 pound) to 6 weeks to get what weight he must gain per week.

= 18 pounds ÷ 6 weeks = 3 pounds per week

He must achieve 3 pounds per week to achieve his goal of 123 pounds.
answer is c) 3 pounds

when the whole is the same why does it take 4 copies of one tenth to equal 2 copies of one fifth draw a model to support your answer

Answers

well 4 copies of one tenth will equal 4 tenths. so when u simplify 4 over ten (4/10 )and divide the top and bottom by the common factor which is 2 then you will get 2 fifths  because 4 divided by 2 is 2 and 10 divided by 2 is 5.

3 + j / 11 = 2


j =__________

Answers

j would equal -11
first subtract 3 so 2 is -1
then divide -1 by 11
so j=-11

This is how you solve it:

3 + j / 11 = 2

3 + j = 2 × 11

3 + j = 22

j = 22 - 3

j = 19

Now you could check your answer by substituting the value of j :

3 + j / 11 = 2

3 + 19 / 11 = 2

22/11 = 2

2 = 2

What is the standard form of x/4 - y/3 =1 and 5/x - 2/y=7.

Answers

You can multiply both sides by a number that will get rid of the denominators. For ex. you can multiply the first equation by 12 because 4 and 3 both go into 12 evenly. MAKE SURE YOU MULTIPLY THE OTHER SIDE BY 12 AS WELL! Therefore, 12(x/4) - 12(y/3) = 12(1), or 3x - 4y = 12
