A.11/8
B.19/8
C.28/8
D.39/8
To find the number, solve the equation: 7.2x - 8 = -29.6
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.

2. In a probability experiment, Eric flipped a coin 42 times. The coin landed on heads 28 times. What is the ratio of heads to tails in this experiment?
A. 2/3
B. 2/1
C. 1/2
D. 2/3
Answer: 1. B. 1:3
2. A.
Step-by-step explanation:
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 :_
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 :-
Hence, the correct option is : A.
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
Answer:
Option A
Step-by-step explanation:
We can try to factorize all the options one by one.
For A:
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 ..
