answer:
-2x + 9 or -2 which is what the question asks
step-by-step explanation:
- we have to combine like terms which means terms that are similar
- in this, only 5x and -7x are like terms since both have x with them
- 9 will stay the same since it does not have a like term
5x + 9 + (-7x) = __x + 9
-2x + 9
- therefore, -2 goes in the blank
Check the picture below, those are the x,y pairs or cosine, sine values pair.
now, this is from the Unit Circle, and therefore the hypotenuse or radius wil be 1.
so, just plug in those values... hmmm lemme do the tangent, so you see the division of two fractions.
$26g + $14m ≤ $220
g represents the number of video games bought
m represents the number of movies bought
Answer: 8 posters
Step-by-step explanation:
From the question, we are informed that Lincoln has 16 pins in one box and 17 pins in another box and that he uses 4 pins to hang each posters posted. The total number of posters he can hang with the pins goes thus:
We should first calculate the total number of pins he has.
= 16 + 17 = 33 pins
Since he uses 4 pins to hang a poster, we then divide 33 pins by 4.
= 33 ÷ 4
= 8.25
This means that he can hang 8 posters with the pin
Answer:
temperature on the 5th days was -3 degree Celsius
Step-by-step explanation:
Mean is the average of the numbers
As per the statement:
The mean temperature for the first 4 days in January was 7°C.
Sum of the first 4 days temperature =
It is also given that:
the mean temperature for the first 5 days in January was 5°C.
then;
Sum of the first 5 days temperature =
We have to find the temperature on the 5th days.
Substitute the given values we have;
Therefore, the temperature on the 5th days was -3 degree Celsius
