7/8 = x/48
Cross multiply, which is: a/b = c/d ⇒ ad = bc
After cross multiplying, we get:
8x = 7(48)
8x = 336
Divide 8 on both sides
x = 42
Your final answer is B. 42<span>.</span>
Answer:
Step-by-step explanation:
To calculate the weighted moving average for period 13 with weights 0.4 and 0.3.
P13 = (30.7x 0.4) + (42.0x 0.3)
P13 = 12.28 + 12.60
P13 = 24.88
Answer: -10
Step-by-step explanation:
10 x 4 is 40 so with 2 negatives, it turns positive, and 40 plus 10 = 50
Brianna's thinking is incorrect.
Expessions A, and C. are equivalent.
For C, you add 5x and x together (because they have the same variable) to get 6x - 4.
For A, you subtract 9x and 3x (because they have the same variable) to get 6x- 4.
