8 and 3times a number is 128

mel-nik [20]

You must first set up an equation for this problem. Your equation is 8+3x=128. If we subtract 8 from each side we get 3x=120. If we then divide both sides by 3 we get x=40. Therefore your number is 40 because 8+3*40=128.

Solve the quadratic equation using any method. Round to the nearest tenth if neccessary. Any Help Is Appreciated

Answer:

$x = -0.8\ or\ x = 0.5$

Step-by-step explanation:

Given [Missing from the question]

$6x^2 + 2x - 2.5 = 0$

Required

Solve

Using factorization, we have:

$6x^2 + 2x - 2.5 = 0$

Expand 2x

$6x^2 - 3x+5x - 2.5 = 0$

Factorize

$3x(2x - 1)+2.5(2x - 1) = 0$

Factor out 2x - 1

$(3x +2.5)(2x - 1) = 0$

Split:

$(3x +2.5) = 0\ or\ (2x - 1) = 0$

In both cases, solve for x

$3x = -2.5\ or\ 2x = 1$

$x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}$

$x = -0.8\ or\ x = 0.5$ --- approximated

Computing the ratio of raisins to ounces, it is found that due to the higher computed ratio, brand B advertises the greatest ratio of raisins per ounce.

---------------------------

For brand A, there are 60 raisins in the 24-ounces box, thus the ratio is of $\frac{60}{24} = 2.5$ , that is, 2.5 raisins per ounce.
For brand B, there are 18 raisins in the 6-ounce box, 36 in the 12-ounce, and it follows this ratio, thus $\frac{36}{12} = \frac{18}{6} = 3$ , thus, 3 raisins per ounce.
For brand C, there are 20 raisins in the 10-ounce box, 30 in the 15-ounce, and so on, thus $\frac{20}{10} = \frac{30}{15} = 2$ , thus, 2 raisins per ounce.
Due to the higher computed ratio, brand B advertises the greatest ratio of raisins per ounce.
