On the left side of the equation we have like terms so: -3.5x + 3.2 = -1.2x + 7.7
Add 3.5 to each side: 3.2 = 2.3x + 7.7
Subtract 7.7 from each side: -4.5 = 2.3x
Divide both sides by 2.3: -1.95652174 = x
Answer: -1.95652174
Answer:
9/4 gallons
Step-by-step explanation:
If the rate is 3/4 gallon per 1/3 of an hour, we need to figure out how to make the 1/3 into 1 hour.
Since it's 1/3, you have to multiply it by 3 to get 1. So, multiply 1/3 and 3/4 by 3:
The rate will be 3(3/4) gallons per 3(1/3) hour
The rate will be 9/4 gallons per 1 hour
Hope that helps! :D
Answer:
3 years
Step-by-step explanation:
set two equations in inches and equate
Answer:
-1 and 0
Step-by-step explanation:
X ^4+x = 0;
x*(x^3+1)=0;
x*[(x^3-x)+(x+1)]=0;
x*[x(x-1)(x+1)+(x+1)]=0;
x*(x+1)(x^2-x+1)=0;
Since x^2-x+1=0 has no intersection with the X-axis, there is no x value such that y=0
x=0 or -1
204/68=3, 207/69=3, 210/10=3, 213/71=3, 216/72=3, 219/73=3
