It takes 26.4 days to reach 2 gm.
I’m pretty sure the first one is y = 3x + 2 and the second one is y = -x + 4
When we say "5 is the third part of 15," we do not imply a sequence: the first part, the second part, the third, and so on. When we speak of the third part, that is a different meaning for the word "third." It means each one of three equal parts that together make up the whole
Answer: 78°
Step-by-step explanation:
Looking at the picture, we can tell that ∠ACD and ∠DCB are supplementary angles. This means, they are equal to 180°. With that, we can find x and plug it into ∠DCB.
4x+2+3x+3=180 [combine like terms]
7x+5=180 [subtract both sides by 5]
7x=175 [divide both sides by 7]
x=25
Now that we know x=25, we can plug it in to find ∠DCB.
3(25)+3 [multiply]
75+3 [add]
78
Now, we know ∠DCB is 78°.
