Answer:
x = -64
Step-by-step explanation:
Step 1: Write out equation
9 - 3/4x = 57
Step 2: Subtract 9 on both sides
-3/4x = 48
Step 3: Multiply both sides by -4/3
x = -64
Answer: k(0) = 4; k (2x - 7) = 2x -3
Step-by-step explanation:
If k(a) = a + 4
K(0) will be 0 + 4
K(0)= 4
Then, k (2x - 7) = 2x -7 +4
K (2x - 7) = 2x - 3
Answer:
=2.4 cm
Step-by-step explanation:
In similar plane figures, the ratio of corresponding sides is a constant.
This constant is the linear scale factor.
In the provided example, 1.2cm corresponds to 0.96 while 3.0 corresponds to x
Thus, 1.2 cm/0.96 cm=3.0 cm/x
x=(3.0 cm×0.96 cm)/1.2 cm
=2.4 cm.
The answer to the math probability question you are presenting above would be .475 or (47.5%). The value of 3 years multiplied by 1000 would equal to 3000, thus the person will listen to music 3000 hours a year - which is two standard deviations than the mean. Following the empirical rule, the answer would be .475.
The first thing you would do is square 17,000, which is 298,000,000. Then you would multiply 298,000,000 by 0.10. (or divide the number by 10)
This would get you 28,900,000.
