Answer:
Step-by-step explanation:
The triangles are all similar, so corresponding sides are proportional.
__
<h3>x</h3>
long side/short side = x/6 = 12/x
x² = 72 . . . . . . . multiply by 6x
x = 6√2 . . . . . . take the square root
__
<h3>y</h3>
hypotenuse/long side = y/12 = (12+6)/y
y² = 216 . . . . . multiply by 12y
y = 6√6 . . . . . take the square root
C because it simplifies to 0=0 which proves that it has infinite solutions!
Answer:
3 /4 x+ 1 /2 one-half more than three-fourths of a number
3/ 4 − 1 /2 x three-fourths minus one-half of a number
3/ 4 −(x+ 1/ 2 ) three-fourths minus the sum of a number and one-half

Answer:
39 mg
Step-by-step explanation:
To get the number of milligrams, all we have to do is to find 130% of the RDA
mathematically, we have this as;
130% of 30
= 130/100 * 30 = 39 mg
