LCD means Least Common Denominator. To find the LCD of 3/4, 7/16, & 5/8, we will first get the multiple of each denominator until we get the same multiple of the three denominator
Multiple of
i. 4 are 4, 8, 12, 16
ii. 16 are 16
iii. 8 are 8, 16
16 is the multiple of 4, 16 and 8. So we will use it now as the LCD of the three given fractions.
We can now express the given fractions with the LCD
3/4 = 12/16
7/16 = 7/16
5/8 = 10/16
Answer:
x = 40
Step-by-step explanation:
Given 2 secants to a circle from an external point, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20) ← distribute parenthesis on both sides
64 + 8x = 12 × 32 = 384 ( subtract 64 from both sides )
8x = 320 ( divide both sides by 8 )
x = 40
The corret anwser is actually going to be false! Your math teacher is wrong!
7×3=21 so he has 7 more lawns or 2 1/3 months
The answer to this question would be C, 9. The reason for is cause you remove the parentheses then add the numbers 1.2 + 7.8=9.
