Eight less than 7.2 times a number is -29.6 wrote out in numbers

Answers

7.2x - 8 = -29.6 that is your answer wrote out in numbers.

Final answer:

To find the number, solve the equation: 7.2x - 8 = -29.6

Explanation:

To solve this problem, let's represent the unknown number as 'x'. The equation can be written as 7.2x - 8 = -29.6.

To isolate 'x', we can add 8 to both sides of the equation: 7.2x = -21.6.

Then, divide both sides of the equation by 7.2 to solve for 'x': x = -3.

B. 2/1

C. 1/2

D. 2/3

Answers

Answer: 1. B. 1:3

2. A. $(2)/(3)$

Step-by-step explanation:

The ratio of m to n is written as $(m)/(n)$

1. Given : Rachel has 6 pairs of black shoes and 2 pairs of red shoes.

Then, the ratio of pairs of red shoes to pairs of black shoes will be :_

$\frac{\text{No. of pairs of red shoes}}{\text{No. of pairs of black shoes}}\n\n=\dffrac{2}{6}=(1)/(3)$

Which is written as 1:3.

Hence, the ratio of pairs of red shoes to pairs of black shoes = 1:3

Thus , correct option : B. 1:3

2. Given : In a probability experiment, Eric flipped a coin 42 times. The coin landed on heads 28 times.

Then, the ratio of heads to tails in this experiment will be :-

$(28)/(42)=(2)/(3)$

Hence, the correct option is : A. $(2)/(3)$

the first one is A, because you divide both numbers by two, and make sure they are in the right order.

the answer to the second one is 2/3, because 28 divided by 42 is .66666

Which equation involves a prime quadratic and cannot be solved by factoring? A. x2 + 5x − 4 = 0 B. x2 − x − 6 = 0 C. x2 + 3x − 4 = 0 D. x2 + 6x + 9 = 0 Reset

Answers

Answer:

Option A

Step-by-step explanation:

We can try to factorize all the options one by one.

For A:

$x^(2) +5x-4\n=> x^(2)+4x+x-4\n=>x(x+4)+1(x-4)$

We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.

Moreover we can also note that all the other quadratic expressions can be factorized ..

Answer:

x2 + 5x − 4 = 0
