If sandy has 8 and alex has 6 fewer than alex has 2. Since Jill has 2 then you add 8 plus 2 plus 2 which equals 12. So there is 12 all together

Help me please give brainiest
Eva8 [605]

5. If a = b, and b = c then a = c is the transitive property.

6. The converse is switching the order of the statement.

The answer would be If A <15, then a <10: true

7. You have RS + ST = RT

Using subtraction property  solve for RS by subtracting ST from both sides to get: RS = RT-ST

8. The addition property would be adding the same thing to both sides:

So. If p=q, then p+s = q+s

9. Vertical angles are the same:

6x-22 = 4x+2

Subtract 4x from both sides:

2x-22 = 2

Add 22 to both sides:

2x = 24

Divide both sides by 2:

x = 12

If the area of a rectangle is 12cm2 what could its length be and its width?
lawyer [7]
Hello, 

We know that th formula for the area of a rectangle is: A=b*h
Now, the problem in this excercise is that there is no restriction on the values that b and h can take, so, they can take any value provided that it meets:  b*h=12 cm^{2}
for example:
lenght=  \frac{12}{3}cm \,\,\,\,\,\,and\,\,\,\,width= 3 cm \\  \\ A=\frac{12}{3}cm*3cm \\ A=12 cm^{2}

But if they can only take intenger values, what we have to do is to descompose 12, and then we can analyze the possible solutions.

12   |  2
  6   |  2
  3   |  3
  1

12= 2 *2*3

first option:
12=4*3

Answer: lenght= 4cm   and   width= 3cm  or vice versa

second option:
12=2*6

Answer: lenght= 6cm   and   width= 2cm  <span>or vice versa</span>

Find the midpoint of diagonal AC of ABCD
Vladimir79 [104]

Answer:

M= (1, 3)

Step-by-step explanation:

we have from the picture:

A = (-3,5)

C = (5, 1)

M = Midpoint

M =((x1+x2)/2), ((y1+y2)/2)

so we have:

x1= -3     y1 = 5

x2= 5     y2= 1

M= ((-3+5)/2) , ((5+1)/2)

M = ((2/2) , (6/2))

M= (1, 3)

2) There are 40 boys and 60 girls in a class of students. What is the ratio of girls to students
ra1l [238]

Answer:

60:100, 6/10, 3/5, 6 to 10, etc.

Step-by-step explanation:

You take the number of girls over total students which is boys + girls. Since there's 40 boys and 60 girls, it's 60 girls to 100 students which can be written in several ways.
