Answer:
40 gallons of water and 140 gallons premium antifreeze
Step-by-step explanation:
Let p represent the number of gallons of premium antifreeze in the mix. Then 180-p is the number gallons of water. The amount of pure antifreeze in the mix is then ...
0.90p + 0·(180 -p) = 0.70·180
p = 0.70·180/0.90 = 140 . . . . divide by the coefficient of p
180-p = 40 . . . . . find the water content
40 gallons of water and 140 gallons of premium antifreeze are in the mix.
Answer:
- x² + x + 1 and remainder 2
Step-by-step explanation:
<u>Given</u>
Without using a synthetic division, we can use easier method to find the quotient.
<u>We know the formula:</u>
- x³ - 1 = (x - 1)(x² + x + 1)
<u>Rewrite the given as:</u>
- x³ + 1 =
- x³ - 1 + 2 =
- (x - 1)(x² + x + 1) + 2
This expression, when divided by (x - 1) leave the quotient (x² + x + 1) and a remainder of 2
Answer:
Step-by-step explanation:
property of equality for multiplication, property of equality for multiplication says that if a=b then axc=bxc. If you multiply the same number to both sides of an equation, the equation is still true.
