Answer:
Step-by-step explanation:
let x be the number
2(x+8)=-4x+4
2x+16=-4x+4
6x=-12
x=-2
when you dive the fractions
2/3 = 0.666666
6/10=0.6000
4/5 = 0.80
6/5 = 1.2
so the answer would be 2/3
Answer:
The equation that would be used for the zero product property on will be (x-5)(x-10)=0
Option B is correct.
Step-by-step explanation:
We need to solve the equation 
Solving the equation:
Now, we would factorise to find value of x
So, the equation that would be used for the zero product property on will be (x-5)(x-10)=0
Option B is correct.
Answer:
b. 67
Step-by-step explanation:
In order for the average to be 62, the total of differences from 62 must be zero. The two given numbers have differences of -4 and -1, for a total of -5. In order for the total of differences to be zero, the third number must have a difference from 62 of +5. It must be 62+5 = 67.
Jon's height at his third checkup was 67 inches.
Miko walked a distance of 1.60 km in 30 min. Find her average speed in m/s.
Distance travelled = 1.6km = 1600m
Time taken = 30min = 30*60 = 1800s.
speed = distance/time = 1600/1800 = <u>0.89m/s</u>
