-2(x - 3) = 5(2x + 3)
-2x + 6 = 10x + 15
6 = 10x + 15 + 2
6 = 12x + 15
6 - 15 = 12x
-9 = 12x
-9/12 = x
-3/4 = x or in decimal form; -0.75
hope this helps, God bless!
Answer:
The simplified equation is as follows 2x^5 -x^4 + 9x^2
Step-by-step explanation:
Remove the parentheses around each equation and pair like exponents together
4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2
Then combine the like terms
2x^5 - x^4 + 9x^2
It is in that order due to the proper form being to go from the highest to lowest exponents in an answer
Answer:
13.7 mph
Step-by-step explanation:
• d = st
Given:
- d = 32 miles
- t = 2 1/3 hr = 7/3 hr
Find the rate s:
- s = d/t
- s = 32-7/3 = 32 x 3/7 = 96/7 = 13.7 mph (rounded)
