Answer:
47°
Step-by-step explanation:
Since x and 133° are supplementary (meaning they add up to 180°), x + 133 = 180 so that means x = 47°.
Answer:
25 grams
Step-by-step explanation:
Good effort, but that's not quite right.
Let's call the daily amount of fiber needed x.
One serving of oatmeal provides 16% of the daily amount, or 0.16 x.
The rest of the daily amount is 21 grams.
Together, they add up to the total daily fiber:
0.16 x + 21 = x
Solving for x:
21 = 0.84 x
x = 25
You need 25 grams of fiber daily.
Let's check our answer. 16% of 25 is 4. 4 plus 21 equals 25. So it checks out.
The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2
C. 5 . The greatest common factor is the number that both numbers, 15 and 25, can have a number multiplied into.
For 15, it would be 5x3=15
For 25 it would be 5x5=25
1 isn’t the greatest, 3 isn’t the greatest, 15 cannot go into 25.
