Answer:
11
Step-by-step explanation:
1.80m + 0.6s = 12.00
[substitute the value of m into the equation]
1.80×(3) + 0.6s = 12
5.4 + 0.6s = 12
[make s the subject of the formula]
0.6s = 12 - 5.4
0.6s = 6.6
[divide both sides of the equation by 0.6]
0.6s / 0.6 = 6.6 / 0.6
s = 11
To prove that 11 is correct
[substitute the value of m and s into the equation]
1.80m + 0.6m = 12.00
1.80×(3) + 0.6×(11) = 12.00
5.4 + 6.6 = 12.00
12.00 = 12.00
Answer:
The first statement.
Step-by-step explanation:
Because when you look at the July graph you can see that the highest number of miles is 15 and the lowest number of miles is 1 so the range is 15 - 1 = 14.
When you look at the August graph you can see that the highest number of miles is 13 and the lowest number of miles is 5 so the range is 13 - 5 = 8
So the range of the July month is greater than the range of the August month
Answer:
6x - 15
Step-by-step explanation:
f(x) = 2x + 3 and g(x) = 3x - 9.
![f(g(x))=2(3x-9)+3\\f(g(x))=6x-18+3\\f(g(x))=6x-15](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D2%283x-9%29%2B3%5C%5Cf%28g%28x%29%29%3D6x-18%2B3%5C%5Cf%28g%28x%29%29%3D6x-15)
Answer:
7 feet
Step-by-step explanation:
If it is under .5 keep the whole number the same, if it is .5 or more round up. This is .3 so it is 7.
To subtract fractions, you need to obtain a common denominator. We can achieve this, in this case, by multiplying:
![(\frac{4}{4} * \frac{22}{13}) - (\frac{13}{13}*\frac{21}{4})](https://tex.z-dn.net/?f=%28%5Cfrac%7B4%7D%7B4%7D%20%2A%20%5Cfrac%7B22%7D%7B13%7D%29%20-%20%28%5Cfrac%7B13%7D%7B13%7D%2A%5Cfrac%7B21%7D%7B4%7D%29)
Simplify this:
![\frac{88}{52} - \frac{286}{52}](https://tex.z-dn.net/?f=%5Cfrac%7B88%7D%7B52%7D%20-%20%5Cfrac%7B286%7D%7B52%7D)
Now we have common denominators, so we can easily just subtract the numerators, and we have the answer:
![-\frac{198}{52}](https://tex.z-dn.net/?f=-%5Cfrac%7B198%7D%7B52%7D)
Notice that this is divisible by 2:
![-\frac{99}{26}](https://tex.z-dn.net/?f=-%5Cfrac%7B99%7D%7B26%7D)
That's your answer!
