20. Identity property’s addition
Answer:
b=-11
Step-by-step explanation:
I assume you are looking to solve for the value of b.
<u>3(b+2)</u> x <u>2</u>= <u>4b-10</u>
2 2 4
<u>6(b+2)</u> = <u>4b-10</u>
4 4
x 4 x4
6(b+2) = 4b-10
6b+12=4b-10
-4b -4b
2b+12=-10
-12 -12
<u>2b</u>=<u>-22</u>
2 2
b=-11

Answer:
The answer is 7/24
Step-by-step explanation:
Rewriting our equation with parts separated
=2+16−1−78
Solving the whole number parts
2−1=1
Solving the fraction parts
16−78=?
Find the LCD of 1/6 and 7/8 and rewrite to solve with the equivalent fractions.
LCD = 24
424−2124=−1724
Combining the whole and fraction parts
1−1724=724
Solution by Formulas
converting mixed numbers to fractions, our initial equation becomes,
136−158
Applying the fractions formula for subtraction,
=(13×8)−(15×6)6×8
=104−9048
=1448
Simplifying 14/48, the answer is
=724
