The answer is 2
Step-by-step explanation:
Y2-Y1/X2-X1
4-2/2-1
4-2 ( 2 )
2-1 ( 1 )
2/1 ( 2 )
<span>x+0.1(6) = 0.3(x+6) Simplify and solve for x.
x+0.6 = 0.3x+1.8 Subtract 0.3x from both sides.
0.7x+0.6 = 1.8 Subtract 0.6 from both sides.
0.7x = 1.2 Finally, divide both sides by 0.7
x = 1.71429
So you'll need to add 1.71429 quarts of pure antifreeze to the 6 quarts of 10% antifreeze solution to obtain 7.71429 (6+1.71429) quarts of 30% antifreze solution.</span>
It’s the first option, the fractions added is 1 1/30 making it less than 1.5 gallons
Answer:
10^3
Step-by-step explanation:
10 raised to the third would be the correct power of ten to equal 0.038 if 38 was the numerator.
1.
PP: C=6.80 + (0.90t)
GP: C= 7.30+ (0.65t)
t= 2
(If you set this up in a table of values, the answer will become clear)
2. Let c represent the number of CDs sold today
tot CD's= yesterday + today
110= (3c + 6) + c
110= 4c +6
104 = 4c
c=26
