Answer:
x=6
Step-by-step explanation:
Line ZW and YX are parallel, which means they have the same measurements.
Therefore:
3x+2=20
subtract two from both sides
3x=18
divide by 3
3x/3=18/3
x=6
hope this helps =D
I think its b
Heres my work:
i divided -2 by 2 and got -1
i then subtracted -2 and 2 and got -4
then i added 3 to -4 and got -1
resulting with b
Answer:
Step-by-step explanation:
Let the 10s digit = x
Let the units digit = y
x +y = 11 Sum of the digits = 11
10x + y + 45 = 10y + x Reversed number is 45 more than original #
10x - x + y + 45 = 10y We subtracted x from both sides.
9x + y + 45 = 10y Subtract y from both sides.
9x + 45 = 10y - y Combine the right
9x + 45 = 9y
Put x + y = 11 into the equation just found.
9x + 45 = 9(11 - x) divide through by 9
x + 45/9 = 11 - x add x to both sides
2x + 5 = 11 Subtract 5 from both sides
2x = 11 - 5
2x = 6 Divide by 2
x = 6/2
x = 3
x + y = 11
3 + y = 11
y = 11 - 3
y = 8
Now check it out.
the original number is 38
the new number is 83 which the digits are reversed.
83 - 38 = 45 just as it should.
Answer:
15 times
Step-by-step explanation:
By spinning once, the probability of landing on 2 is 1/8
The probability of landing on 5 is 1/8
The probability of landing on 2 or 5 is 1/8 + 1/8 = 2/8 = 1/4
So spinning 60 times, the number of times we expect a landing on 2 or 5 will be ;
1/4 * 60 = 15 times
