Answer:
x=6 y=-3
Step-by-step explanation:
A. 1/20 x 200
D.10
To figure out what 5% of 200 is, you would multiply 200 by .05.
To figure out if 1/20 of 200 is 10, simply divide 200 by 20.
Hope that helps!
X=number of hours, when Ori drove at 55 mph
y=number of hours, when Ori drove at 40 mph
We can suggest the next system of equations:
x+y=4.25
55x+40y=203.75
We solve this system of equation by substitution method.
x+y=4.25 ⇒y=(4.25-x)
55x+40(4.25-x)=203.75
55x+170-40x=203.75
15x=203.75-170
15x=33.75
x=33.75/15=2.25
y=(4.25-x)=4.25-2.25=2
Answer: Ori drove 2.25 hours at 55 mph and 2hours at 40 mph.
Answer: The number is =5
Step-by-step explanation:
21 + 3X = ("Difference means subtract.) 2X
Twenty-one more than three times a number is equal to the difference between 46 and twice the number
Then write the proper equation: 21+3x= 46-2x.
Next get rid of the smaller "x" so 3x+2x=46-25
solve X
5x=25
x=5
Thank you
