D) (10 x 55) + (10 x 55) + (10 x 55) + (10 x 55)
use distributive rule to factor out 55:
55 (10+10+10+10) = 55×40
Answer:
soory i need more points
Step-by-step explanation:
Answer:
I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:
5(-2)(2) = ?
-10 x 2 = ?
? = -20
-20 ≠ 20
Step-by-step explanation:
Justificaiton:
5(x)(2) = 20
10(x) = 20
10/10(x) = 20/10
x = 2
Second Justification:
5(x)(2) = 20
5/5(x)(2) = 20/5
2x = 4
2x/2 = 4/2
x = 2
Answer:
incorrect
Step-by-step explanation:
this is because it would be 1/2 and 1/6. you would have to multiply the bases for a probability of 1/12
The best answer would be C
