Set it up like a regular equation. I used:

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
Answer:
16 oranges
Step-by-step explanation:
The ratio of oranges to apples is 4:3 which means that for every four oranges, there are 3 apples.
Since there are 12 apples in the basket, to find the number of oranges, set up a ratio.
4/3 = x/12 (x represents the number of oranges)
Cross multiply.
48 = 3x
Divide by 3.
x = 16
There are 16 oranges in the basket.
Hope that helps.
Answer:
They are both correct but they rounded to different places. Scrooge rounded to the nearest whole number while Bon rounded to the nearest tenth.
Step-by-step explanation:
Scrooge rounded up to the next whole number which was three because the tenth place value was 5 or greater.
While Bob on the other hand rounded to the nearest tenth. Which resulted in the number going down because the number in the hundredth place value was less than 5.
Answer:
g = 12.7 cm
Step-by-step explanation:
Here, we want to find the length of the side g
To do this, we shall employ the use of the cosine rule
Mathematically, by using the general form of the rule, we have it that ;
g^2 = e^2 + f^2 -2efCosG
So we have;
g^2 = (9.8)^2 + (3)^2 - 2(9.8)(3) cos 167
g^2 = 162.33
g = √162.33
g = 12.7
