So there are x girls and x-4 boys and together they make 28:
x+x-4=28
2x-4=28
2x=32
x=16
so there are 16 girls and 12 boys.
the ratio is then 16:12, or we can simplify (by dividing both sides by 4): 4:3
so the best answer is 4:3.
Okay first off. You want to combine like terms.
2.75-1.5=1.25j
2.25+3=5.25
Now you just fit those two answers into the final answer and you have:
1.25j+5.25.
Answer:
Step-by-step explanation:
<h3>Given </h3>
- Points A(-1,7) and B (11,-1)
<h3>To find</h3>
<h3>Solution</h3>
<u>Using midpoint formula</u>
- x = (-1 + 11)/2 = 10/2 = 5
- y = (7 -1)/2 = 6/2 = 3
Midpoint is (5, 3)
You can think of this equation as

and thus apply the transformations to it as such



1) D = 2, C = +3
2) D = -12, C = -2
3) C = +6, D = 3
4) C = -7, D = -7
