25 meters = 25 x 100 = 2500
25 meters = 2500 cm
Answer:
996
Step-by-step explanation:
the three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8
x = 9
x = y = 9
z = 1/3(18)
z = 6
Answer:
<ZXY <YXZ and <X
Step-by-step explanation:
don't forget to put the angle sign. it's the blue button all the way on the left in the picture. I used the less then sign in my answe above.
Answer:
(8)(21) = 12x
Step-by-step explanation:
(8)(12) = 21x
(8)(21) = 12x
(12)(8) = 12x
(12)(21) = 8x
Opposite : Adjacent
12 in : 21 in
Opposite : Adjacent
8 in : x in
Equate both ratios to solve for x
12 : 21 = 8 : x
12 / 21 = 8 / x
Cross product
(12)(x) = (21)(8)
12x = 168
x = 168 / 12
= 14
x = 14
Let's look at an example.
We'll add the fractions 1/6 and 1/8
Before we can add, the denominators must be the same.
To get the denominators to be the same, we can...
- multiply top and bottom of 1/6 by 8 to get 8/48
- multiply top and bottom of 1/8 by 6 to get 6/48
At this point, both fractions involve the denominator 48. We can add the fractions like so
8/48 + 6/48 = (8+6)/48 = 14/48
Add the numerators while keeping the denominator the same the entire time.
The last step is to reduce if possible. In this case, we can reduce. This is because 14 and 48 have the factor 2 in common. Divide each part by 2.
The fraction 14/48 reduces to 7/24
Overall, 1/6 + 1/8 = 7/24
