23.55 - 20.65 = 2.9
2.9 / 20.65 = 0.140436
0.140436 x 100 = 14.0436
Therefore that to the nearest tenth of a percent would be:
14% increase
The answer to this is 9 162 divided by 18 is 9
Step-by-step explanation:
multiplying expressions.
remember every term of one expression has to be multiplied with every term of the other expression, and the results are added up (while considering their individual signs, of course).
1.
(-3×3 + 2x - 4)(3x - 2)
(-9 + 2x - 4)(3x - 2)
(-13 + 2x)(3x - 2) = -13×3x + -13×-2 + 2x×3x + 2x×-2 =
= -39x + 26 + 6x² - 4x = 6x² - 43x + 26
2.
let's do the other multiplication and compare the result with the result of 1 :
(-13 + 2x)(2x - 3) = -13×2x + -13×-3 + 2x×2x + 2x×-3 =
= -26x + 39 + 4x² - 6x = 4x² - 32x + 39
no, this product is not the same as in 1.
The answer is letter b.
$4.20 / 60 ounce is the rate for the glass bottle while $3.06 / 51 ounces is the rate for the plastic one.
Simplified, the glass bottle is $0.07 / ounce while the plastic bottle is $0.06 / ounce.
Ergo, the plastic bottle is cheaper by a cent per ounce.
