Suppose the number is x, its reciprocal is 1/x
x+1/x=13/6
(x^2+1)/x=13/6
6(x^2+1)=13x
6x^2-13x+6=0
(3x-2)(2x-3)=0
x=2/3 or x=3/2
Answer:
36
Step-by-step explanation:
3(15.9 - 3.9)
3 · (15.9 - 3.9)
3(15.9) - 3(3.9)
47.7 - 3(3.9)
47.7 - 11.7
36
Answer:
y is equal to 4.
Step-by-step explanation:
To find this, cross multiply and then divide.
10*2 = y*5
20 = 5y
4 = y
Answer:
/2=1.41
/5=2.24
(a)^2+(b)^2=(c)^2
(1.41)^2+(b)^2=(2.24)^2
2+(b)^2=5
(b)^2=5-2
(b)^2=3
b=/3 or 1.73
Step-by-step explanation:
for a triangle, a missing value of the side can be found using pythagorean theorem which is (a)^2+(b)^2=(c)^2
replace it with the given value.
*note:(c)^2 should be the hypotenuse
inverse of +ve is -ve
inverse of square is square root
<h3>x = 21/5</h3>
Step-by-step explanation:
<h3>___________________________</h3>
<h3>Given →</h3>
5x:9 = 7:3
<h3>So,</h3>
→ 5x/9 = 7/3
→ x = (7 × 9)/(3 × 5)
→ x = 21/5
