Answer:
x = 2.5
Step-by-step explanation:
4x-1/2 = x+7
4x-x = 7+0.5
3x = 7.5
x = 2.5
1 gal = 3.8 liters....so 65 gallons = 65 * 3.8 = 247 liters
just to clarify the engineering notation, E6 is just 1 and 6 zeros, or a million, thus, 107,000,000 is just 107E6.
B. Annually 2 years would equal 9%. 540/2=270.
3,000x9%=270.
Altogether would be 18%. But, if we’re solving it for each separate year, then it would be 9%.
10 x 200 is 2000
therefore there are 200 tens .
