The first three are true

Answer:

12 girls to 27 students

5 boys to 9 students

15 boys to 12 girls

Step-by-step explanation:

The first thing we have to know is that the total number of students is 27 .

- 12 girls to 27 students  is correct because there are 12 girls out of a total of 27 estudiantes

- 5 boys to 9 students is correct because it uses a common denominator that is 3  (boys: 15 / 3 = 5 and students: 27 /3 = 9)

- 15 boys to 12 girls is saying the same of the statement

The last one 3 girls to 5 boys does not have a common denominator for both factors so this last option is false .

The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A
Hope this made sense!!

Answer:

|x + 12|

Step-by-step explanation:

The question I took form you I assume looks like this...

|x - (-12)|

Therefore, if we simplify this, the answer is |x + 12|

This is the answer because you would multiply -1 by -12

seropon [69]
12 ounces will be left in the bottle

Turn the 1/4 into a decimal which is 0.25 and times that by 20 and you’ll get 5, 5 is the amount of ounces you poured for your friend. Subtract 20 ounces by 5 ounces and you’ll get 15 ounces, then subtract 15 by 3 which is the amount of juice you poured for yourself and you’ll be left with 12 ounces in the bottle.
