Answer: $19x
Step-by-step explanation:
If she bought 2 racing cars,
= $5x +$5x = $10x (Because one car is 5x)
And if she bought 3 motor cycles,
= $3x + $3x $3x = $9x
Now we get our total amount = $10x + $9x = $19x
Hope I could help! :)
Answer:
there is no answer may you show it please so we can help you please thank you very much
Step-by-step explanation:
Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72
Hope this helped :)
Answer:
120
Step-by-step explanation:
As x goes from 1 to 2, y increases by 4 from 4 to 8
As x goes from 2 to 3, y increases by 4 from 8 to 12
We increase by 4 each time
The formula for an arithmetic sequence is
an = a1+d(n-1)
where a1 is the first term which is 4
d is the common difference or the number we add each time which is 4
n is the term we are looking for which is 30
a30 = 4 +4 (30-1)
a30 = 4+4(29)
= 4+116
= 120
8.992254284692088 is the radius I believe
