Answer:
A) x=3 or x=6
Step-by-step explanation:
Factor out the GCF : 2(x^2-9x+18)
Then, set to zero.
2(x^2-9x+18)=0
2(x-3)(x-6)=0
x=3 or x=6
Answer:
45°
Step-by-step explanation:
in straight lines that intersect like this, if one angle is 55°, the one opposite to it will be equivalent. this means (x+10)° equals 55°. then you work out what x is. so x+10=55 so we can subtract 10 from both sides to get x=45°
Answer:
n = 6 is closest to the correct value.
Step-by-step explanation:
For the terminal side to fall on the y-axis, the angle must be a multiple of 90 degrees. Setting (525n)° = (90)°, or n = 525/90 = 5 5/6.
The answer n = 6 is closest to this result.
Answer:
35 Quarters and 36 Dimes
Step-by-step explanation:
d + q = 71
10 + 25 = 1235
10 x 36 = 360
25 x 35 = 875
360 + 875 = 1235
Step-by-step explanation:
22/40 = 11/20 = (11 * 5)/(20 * 5) = 55/100.
