5a - (-2a) + 9

When you subtract a negative number, you can replace the 'double negative' with a positive, or addition. So, instead of subtracting -2a, you can add 2a.

5a + 2a + 9 Combine like-terms

7a + 9

Negative times negative is positive so it makes it 7a +9 since it’s out of the parentheses

An old coin is sold for $2 and its value increases by 8% each year after it is sold. What is the value of the coin, in dollars,

spayn [35]

Principal=P=$2
Rate of interest=8%=R
Time=T=10years

Interest be I

$\\ \sf\Rrightarrow I=\dfrac{PRT}{100}$

$\\ \sf\Rrightarrow I=\dfrac{2(8)(10)}{100}$

$\\ \sf\Rrightarrow I=\dfrac{280}{100}$

$\\ \sf\Rrightarrow I=2.8\$$

Now

Value of coin after 10years =2+2.8=4.8$

Choose the set of equivalent fractions that correctly uses the LCD for these fractions: 2/9 and 5/12

Svetradugi [14.3K]

Step-by-step explanation:

the lowest common denominator (LCD) is the lowest common multiple (LCM) of the denominator numbers (the ones at the bottom of the fractions).

finding the LCM of 9 and 12 using the prime factor method :

9 = 3×3

12 = 2×2×3

the LCM is the combination of the longest chains per prime factor. which means we have 2×2 and 3×3 as longest chains for 2 and 3.

LCD = LCM = 2×2×3×3 = 36

2/9 turns into x/36 by multiplying by 4/4 :

2/9 × 4/4 = 8/36

5/12 turns into x/36 by multiplying by 3/3 :

5/12 × 3/3 = 15/36

so, the third answer option is correct.
