Answer:
x = - 5
Step-by-step explanation:
Given
5x + 7 = 2x - 8 ( subtract 2x from both sides )
3x + 7 = - 8 ( subtract 7 from both sides )
3x = - 15 ( divide both sides by 3 )
x = - 5
-3.2b + 9
by adding like terms together.
Answer:
A. 2.25
Step-by-step explanation:
-3x + 10 = 5x - 8 (Given)
10 = 8x - 8 (Added 3x on both sides)
18 = 8x (Added 8 on both sides)
2.25 = x (Divided 8 on both sides)
First you divide 380 by 100 to get what 1% is, (3.8) and then you multiply by 18 to give you 18%. The answer is 68.4, so add that to 380 and you'll have the final answer of 448.4.
