a=a
a/a=1 where a=a


a. 3+3/3=3+1=4

b. 2+2/5+2+2/5=2+2+2/5+2/5=4+2/5+2/5=4+4/5=4 and 4/5


c. 3+3/8+1+5/8=3+1+3/8+5/8=4+3/8+5/8=4+8/8=5+1=6

2 1/3 + 1 2/3 = 3 3/3

2 1/3 + 1 2/3 = 4
2 + 1 = 3; 1/3 + 2/3 = 1
3 + 1 = 4

3 3/3 = 4
3 = 3; 3/3 = 1
3 + 1 = 4

Now, let's come up with a fraction that is equal to 4.

2 6/3

This answer works because we already have 2 as an integer, and 6/3 is 2.
2 + 2 = 4

Hope this helps!

Your brother is 1/3 your age. Your sister is 4 years older than your brother. Your sister is 9 years old. Write and solve an equ
kati45 [8]

Answer:

Your age(a) is 15 in this case.

If your brother is 1/3 of your age, that means multiply your brother's age by 3

Your sister is 9, and is 4 years older than your brother. In that case, we now know that your brother is 5

With that information, we can put this into a valid equation.

------------------------------------------------------------------------------------------------------------

<em>turn 1/3 into a flipped fraction, 3/1 which is equal to 3</em>

<em>your brother's age is 5, so the first value would be 5</em>

<em>5 times 3 is 15, so that means a is 15</em>

5 * 3/1 = 15

the area of 4 walls and ceiling of a room is 107 metre per square. if the room is 6m long and 5m wide, how high is the room?
lawyer [7]

Area of ceiling: 6 x 5 = 30 square meters:

Area of 4 walls = 107 - 30 = 77 square meters

2 walls = 6 + 6 = 12 meters long

2 walls = 5 + 5 = 10 meters long

12 + 10 = 22

77 square meters / 22 meters = 3.5 meters

The walls are 3.5 meters high.

We probably couldn't go to all the stars because they're too far away. It would take a long time to get there.
Dvinal [7]

Answer:

The correct answer is B. Contain generalizations and contractions.

Step-by-step explanation:

A generalization occurs when a specific idea is applied to a general category, in simple terms it occurs if a person states something always occur because this person saw it once. In this case, generalization occurs as this person affirms all stars are too far away and thus it will take a long time to get to those stars, however not all stars are as far away as this person believes and this does not mean it will take a long time to get there as new technology can be created, thus, this statement is not true and need revision. On the other hand, contractions refers to the process of shortening words by putting them together, this can be seen in "couldn't" ( could + not) and  "they're" (they + are), contradictions are not correct as they should not be used in formal language and be avoided, thus, contradictions also need to be revised.
