Answer:
Division Property of Equality
Step-by-step explanation:
→In Step 4, it is shown that the equation is:
3x = 30
→However, to solve for x, you must get it by itself. This means you need to get rid of the 3 that's being multiplied. So since the 3 is being multiplied to x, you must do the opposite of multiplication, which is division.
→As you can see, the total of 30 is decreased in Step 5, since it has been divided by 3, giving you a total of 10.
This shows that the property of equality that yields Step 5 is the <u>Division Property of Equality.</u>
Answer:
41/35
Step-by-step explanation:
Simplify the following:
4/7 + 3/5
Put 4/7 + 3/5 over the common denominator 35. 4/7 + 3/5 = (5×4)/35 + (7×3)/35:
(5×4)/35 + (7×3)/35
5×4 = 20:
20/35 + (7×3)/35
7×3 = 21:
20/35 + 21/35
20/35 + 21/35 = (20 + 21)/35:
(20 + 21)/35
