B
Step-by-step explanation:
A number increased by 7 means, 7 was added to the number and the result is 15
it takes mrs. jordan 24 minutes to complete 12 questions.
if she completes each question in 1/2 a minute, then:
1/2 / 12 questions = 24 minutes.
Answer:
9 (2 a - 3)^2
Step-by-step explanation:
Simplify the following:
(6 a - 9)^2
Hint: | Factor out the greatest common divisor of the coefficients of 6 a - 9.
Factor 3 out of 6 a - 9:
(3 (2 a - 3))^2
Hint: | Distribute exponents over products in (3 (2 a - 3))^2.
Multiply each exponent in 3 (2 a - 3) by 2:
3^2 (2 a - 3)^2
Hint: | Evaluate 3^2.
3^2 = 9:
Answer: 9 (2 a - 3)^2
Probability of an event= number of ways an event can occur / total number of possible outcomes.
Probability = 6/12 = 0.5
Answer:
She used the addition property of equality:
p2 + 5 = 8p - 7
+7 +7
p2 + 12 = 8p
